Who Are the Best Baseball Players of All Time?

Why the Debate Persists

Every season, new players emerge and old legends are revisited, keeping the question alive: who are the best baseball players of all time? The conversation spans generations, mixing nostalgia with data-driven analysis.

Fans lean on iconic moments, while analysts dive into advanced metrics. This blend of emotion and calculation fuels endless debate.

Key Factors That Shape Rankings

To answer the question objectively, you must weigh several criteria. Each factor tells a different part of a player’s story.

Offensive Production: Traditional stats like HR, RBI, and batting average are complemented by OPS and OPS+.
Pitching Dominance: WAR, ERA+, and strikeout totals gauge a pitcher’s impact.
Era Adjustment: Metrics such as OPS+ normalize performance across ballpark, equipment, and competition differences.
Defense & Fielding: Defensive Runs Saved (DRS) and Ultimate Zone Rating (UZR) highlight glove work.
Clutch & Postseason: 5-game and 10-game postseason stats capture performance under high pressure.

Example: Comparing Ruth and Trout

Take Babe Ruth and Mike Trout. Ruth’s raw numbers: 714 HR, 2.94 OBP, 1.23 OPS. Trout’s: 600+ HR, 0.330 OBP, 0.975 OPS. At first glance, Ruth seems superior.

But when adjusted for era, Trout’s OPS+ is 170, while Ruth’s is 138. This shows Trout’s performance relative to his peers is higher.

Thus, era adjustment flips the narrative for the modern era.

Actionable Tools for Your Own Ranking

Want to create your own all‑time list? Follow these steps.

Collect WAR data from Baseball‑Reference or FanGraphs. Focus on career WAR for a holistic view.
Normalize offensive stats with OPS+; for pitchers, use ERA+.
Include defensive metrics like DRS or UZR to capture complete impact.
Factor in postseason performance by adding a weighted bonus (e.g., +0.5 WAR per postseason win).
Rank players by a composite score: Composite = WAR + (OPS+–100)/10 + (ERA+–100)/10 + DRS/20 + Postseason Bonus.

Run this calculation on a spreadsheet for quick visualization.

Data Spotlight: Top 5 Players by Composite Score

Applying the composite method yields the following leaders (values are illustrative).

Rank	Player	Composite Score
1	Mike Trout	102.5
2	Babe Ruth	98.3

1. Key Criteria for Ranking the Greatest Baseball Players

When you ask who are the best baseball players of all time, the answer hinges on a mix of raw numbers and context. Let’s break it down into four actionable categories that every analyst, fan, and trivia night champion should master.

On‑Base Plus Slugging (OPS) as a Benchmark

OPS blends on‑base percentage (OBP) and slugging percentage (SLG) into one figure that reflects both plate discipline and power.

Top hitters regularly post OPS > .950; Babe Ruth’s career OPS was an astonishing .927.
Mike Trout’s 2023 OPS of 1.147 tops the all‑time current‑era record.
Use OPS+ (league‑adjusted) to compare players like Hank Aaron (OPS+ 134) against modern power rushes.

Action: Build a simple spreadsheet that pulls OPS, OPS+, and average per season. Flag players whose OPS+ > 120 over at least ten seasons.

ERA and Wins for Pitching: The Equivalent of OPS for Arms

Just as batting metrics quantify offense, ERA and WHIP gauge pitching dominance.

Cy Young’s career ERA of 2.63 remains the lowest among pitchers with over 4000 innings.
Roger Clemens’ 2.56 ERA in 2004 still ranks in the top ten all‑time.
Combine ERA+ (league‑adjusted) with WAR to spot era‑specific excellence.

Action: Create a “Pitcher Power Index” by averaging ERA+ and WAR. A player with an ERA+ > 130 and WAR > 80 is a likely contender for the all‑time list.

Era Adjustments and Advanced Analytics

Baseball’s landscape changes every decade. Sabermetrics level the playing field.

WAR (Wins Above Replacement) aggregates offense, defense, and baserunning. Babe Ruth’s WAR of 110.6 dwarfs modern stars.
OPS+ and ERA+ normalize for park and league factors, turning raw numbers into relative performance.
Use OPS‑ERA+ ratio to evaluate balanced skill—players with high numbers in both categories are rare.

Action: Run a “normalized greatness” test by calculating each player’s OPS+ * 0.5 + ERA+ * 0.5. Rank the top 10 by this metric.

Intangible Contributions: The Qualitative Edge

Stats can’t capture everything, but leadership, clutch moments, and defensive brilliance shape a legacy.

Clutch hitting: Calculate clutch OPS (OPS in the 8th inning or later, with the game in the balance) to spot true game‑changers.
Defense: Fielding Independent Pitching (FIP) removes defensive influence, while Defensive Runs Saved (DRS) highlights outfielders like Willie Mays.
Leadership: Qualitative analysis—team championships, MVP awards, and anecdotal accounts of locker‑room presence.

Action: Create a “Legacy Score” by adding one point for each championship, MVP, and Hall of Fame induction. Players above 15 points merit deeper consideration.

Putting It All Together: A Quick Ranking Formula

Combine the quantitative and qualitative tools into a single score:

Weighted OPS+ (35%)
Weighted ERA+ (35%)
WAR (20%)
Legacy Score (10%)

Run this formula on your dataset. The top five will answer the question, “who are the best baseball players of all time?” with data-backed confidence.

Unlocking the Data: How to Spot the Best Baseball Players of All Time

Start with the Core Metrics

Begin your deep dive by comparing OPS and WAR, the two foundations for evaluating greatness. OPS blends on‑base ability with slugging, while WAR quantifies overall value to a team. A player with an OPS above .900 and a WAR exceeding 70 is likely in the conversation for the best baseball players of all time.

Normalize Across Eras with OPS+ and WAR+

Raw numbers can mislead when eras differ. OPS+ and WAR+ adjust for ballpark factors and league averages. For example, Babe Ruth’s 200+ OPS+ in the 1920s eclipses modern hitters with a 180+ OPS+ despite lower raw totals, underscoring his dominance.

Pinpoint Peak Performance Periods

Identify stretches where players ran their best numbers. A player’s prime years—often 5–7 seasons—can be a decisive factor. Mike Trout’s 2019 season, with a 1.216 OPS+ and 1.023 WAR+, is a textbook example of elite peak performance.

Factor in Postseason Impact

Track postseason stats separately; a player’s ability to elevate in high‑stakes games matters.
Take the 2019 World Series MVP, Pete Alonso, who hit 8 home runs, 29 RBIs, and maintained a .557 OBP.
Compare postseason WAR to regular‑season WAR for a fuller picture.

Balance Off‑Field Influence with On‑Field Numbers

Greatness isn’t purely statistical. Leadership, clutch hitting, and cultural impact enrich a player’s legacy. Willie Mays led the 1958 World Series with a 1.000 batting average, cementing his status beyond raw numbers.

Leverage Advanced Defensive Metrics

Modern analytics like Defensive Runs Saved (DRS) and Ultimate Zone Rating (UZR) bring defense into the conversation. Ichiro Suzuki’s 61 DRS in 2005 illustrates how a player can dominate both offensively and defensively, crucial for any best‑all‑time list.

Create a Multi‑Layered Scoring System

Statistical Tier (40%) – OPS, WAR, OPS+, WAR+.
Era Adjustment (20%) – Adjusted per league average.
Clutch Factor (15%) – Postseason WAR and game‑winning hits.
Intangible Qualities (15%) – Leadership, influence, and legacy.
Longevity (10%) – Career length and durability.

Assign each player a score per category, then sum for a composite ranking. This transparent method shows why Babe Ruth tops most lists with a composite score of 95/100.

Use Visualization Tools to Spot Trends

Graphs can reveal patterns that raw tables hide. Plot a player’s OPS+ over time to see consistency. A line graph of Hank Aaron’s OPS+ demonstrates a steady decline after 1970, explaining why his early dominance outweighs later years in many rankings.

3. Pitching Greats Who Dominated the Mound

Pitchers shape the rhythm of baseball, turning simple tosses into legendary moments. Their mastery of velocity, command, and strategy has defined eras and inspired generations of teams and fans.

Walter Johnson: The Big Nose

Walter Johnson’s career, spanning 1914‑1930, redefined what a pitcher could achieve with pure arm strength.

He posted a career ERA of 2.17, the lowest for a pitcher with over 4,000 innings pitched, while compiling 3,509 strikeouts.

Johnson’s fastball was legendary; contemporary accounts describe it as “a baseball traveling at 100 miles per hour.”

He led the American League in strikeouts eight times and captured the AL MVP award in 1918.

Modern sabermetricians credit Johnson with an estimated ERA+ of 151, placing him firmly in the top 10 all‑time pitchers.

Cy Young: The Marathon Master

Cy Young’s 20‑season career (1901‑1921) yielded 511 victories, a record still unbroken.

He amassed 7,356 strikeouts, a total that remained a benchmark until Nolan Ryan surpassed it in 1988.

Young’s durability is evident in his 7,356 innings pitched, translating to an ERA of 2.63.

In 1913, he posted a 1.20 ERA, the lowest in a single season over 15 years of play.

His 1946 post‑season interview illustrated his mental toughness: “I never let the ball get me; I let the ball get me.”

Roger Clemens: The Modern Dominator

Roger Clemens’ career (1984‑2007) showcases a blend of power, precision, and adaptability.

He recorded 4,672 strikeouts, ranking him seventh on the all‑time list, while maintaining a 3.12 ERA.

Clemens earned seven Cy Young Awards, a testament to his sustained excellence across four decades.

His 1991 season remains one of the most dominant pitching campaigns, with an ERA of 1.70 and a 1.89 WHIP.

Advanced metrics award Clemens a career WAR of 107.6, underscoring his impact beyond traditional stats.

How to Apply These Pitching Legends to Your Own Analysis

When evaluating contemporary pitchers, compare their ERA+ and WAR to these historical benchmarks.

Use ERA+ to normalize ERA across different ballpark and era conditions.

Consider strikeout-to-walk ratios (K/BB) to gauge command and control.

Example: A modern pitcher with a 3.00 ERA+ and 5.2 K/BB matches Clemens’ dominance in efficiency.
Example: A pitcher with a 2.50 ERA+ but 2.0 K/BB may struggle with control, limiting their legacy.

Incorporate advanced fielding metrics (FIP, DRS) to assess how much defense influences your pitcher’s success.

Finally, evaluate postseason performance; a pitcher who excels under playoff pressure often elevates their career legacy.

4. All‑Around Stars Who Excelled Off the Field and On It

When debating who are the best baseball players of all time, it’s essential to look beyond raw power numbers. The most enduring legends combine hitting, defense, base‑running, and leadership into a single package that reshapes the game across generations.

Albert Pujols: Consistency and Longevity

Albert Pujols’ career is a masterclass in sustained excellence, spanning 20 seasons with the St. Louis Cardinals, Los Angeles Angels, and Los Angeles Dodgers.

He amassed 3,060 hits, 1,024 RBIs, and 5,093 total bases—figures that place him in the top five of each category among all‑time MLB leaders.

His 2004 season remains a benchmark: a .331 batting average, 39 home runs, and 139 RBIs with a .981 OPS+, the highest single‑season OPS+ in modern history.

Actionable insight: When compiling your own list of best baseball players, use Pujols’ career WAR (173.4) as a yardstick for long‑term value beyond peak performance.

Beyond the numbers, Pujols’ leadership off the field—coaching youth clinics, serving on the MLB Players Association, and championing mental health—show how character amplifies on‑field greatness.

Mike Trout: The New‑Era Phenomenon

Mike Trout has redefined what a modern superstar can look like, blending raw power with elite speed and field‑covering range.

Since debuting in 2011, Trout has recorded a career OPS of 1.119 and an OPS+ of 172, a level of offensive production rarely seen since the 1970s.

Defensively, he has won three Gold Gloves at center field, demonstrating that elite fielding can coexist with peak batting.

Actionable insight: To evaluate contemporary players, compare Trout’s 100+ WAR seasons against historical greats—his 2015 season (WAR 12.8) ranks among the top 10 single‑season WAR totals in MLB history.

Trout’s discipline—maintaining a 32% strikeout rate and 29% walk rate in the 2023 season—illustrates how plate discipline fuels sustained productivity.

Ichiro Suzuki: The Speedster Icon

Ichiro Suzuki’s arrival in MLB in 2001 introduced a new era of contact hitting and base‑running acumen.

He logged 3,089 hits, the most in MLB history until surpassing Pete Rose in 2022, and led the league in hits four times.

Ichiro’s 2004 season produced a .372 batting average, 25 home runs, and 116 RBIs—highlighting that power and contact can coexist.

5. Comparison Table of the Top 10 Baseball Players

The table below offers a quick snapshot of the “best baseball players of all time,” but to truly understand why these names dominate the conversation, you need to dive deeper. Below, we unpack each metric, compare the players side‑by‑side, and give you actionable take‑aways for crafting your own all‑time rankings.

Rank	Player	Era	Career OPS	WAR	Hall of Fame
1	Babe Ruth	1919‑1935	0.927	110.6	✔️
2	Hank Aaron	1954‑1976	0.743	86.5	✔️
3	Willie Mays	1951‑1973	0.716	84.0	✔️

Why OPS and WAR Matter in the Great‑ness Debate

On‑Base Plus Slugging (OPS) measures a player’s ability to get on base and hit for power, a key indicator of offensive value. WAR (Wins Above Replacement) aggregates offense, defense, and baserunning into a single figure.

For example, Babe Ruth’s OPS of 0.927 ranks in the top 10 all‑time, while his WAR of 110.6 reflects unmatched contributions across every facet of the game.

Comparing the Top Three: Key Take‑aways

Babe Ruth – Dominated the dead‑ball era and set a new standard for power hitters. His 714 home runs (a record until 2007) and 1,776 RBIs illustrate raw output.
Hank Aaron – Surpassed Ruth’s home‑run record with 755 homers, showcasing consistency over 22 seasons. Aaron’s 2,297 RBIs rank #2 all‑time.
Willie Mays – A complete player with 660 home runs, 2,190 RBIs, and an All‑Star Rookie of the Year award. Mays’ defensive brilliance earned him 12 Gold Gloves.

How to Use the Table for Your Own Rankings

Normalize Across Eras – Adjust OPS and WAR using era‑adjusted metrics like OPS+ and WAR+. For instance, a 100 OPS+ indicates league average; Ruth’s OPS+ was 182, showing he was 82% better than the league average.
Weight Postseason Performance – Add a “ postseason WAR” column if you value clutch play. Mike Trout’s postseason WAR in 2019 was 1.8, a career‑high.
Consider Longevity vs. Peak – Players like Albert Pujols (6,400+ plate appearances) demonstrate durability. Compare his 7.9 WAR per season to Ruth’s 5.3.
Include Intangibles – Leadership and influence can be quantified through contemporary accounts or Hall of Fame voting trends. Ruth’s 10 MVP awards (though unofficial in his era) attest to his impact.

Expanding the Table: Add These Columns for Depth

OPS+ (Era‑Adjusted) – Allows fair comparison between eras.
Defensive Runs Saved (DRS) – Highlights defensive contributions.
Postseason OPS/ERA – Measures clutch performance.
Career Wins (for pitchers) – Essential for evaluating the “best pitchers” sub‑list.

By layering these additional data points, you transform a static table into a dynamic decision‑making tool. Whether you’re a blogger compiling a list for your readers or a data scientist testing new sabermetric models, this enhanced framework will help you rank the best baseball players of all time with clarity and confidence.

6. Expert Tips: How to Evaluate Baseball Greats for Your Own List

Crafting a personal ranking of the best baseball players of all time requires more than just eye‑balling stats. Below are concrete, data‑driven steps that will help you build a balanced, evidence‑based list.

1. Start with Era‑Neutral Metrics

Traditional numbers like home runs or RBIs can be misleading when comparing eras with different ballparks, pitching quality, and game speed. Use WAR (Wins Above Replacement) to gauge overall value relative to a replacement player.

For example, Babe Ruth’s career WAR of 110.6 ranks third all‑time, while Mike Trout’s current WAR of ~38 already places him in the top 10 of modern players.

Complement WAR with OPS+ (On‑Base Plus Slugging Plus) and ERA+ (Earned Run Average Plus), which adjust for league and park factors. A player with an OPS+ above 150 performed 50% better than the league average hitter.

2. Incorporate Advanced Defensive Statistics

Defense is often overlooked but can swing a player’s ranking. Fielding metrics such as UZR (Ultimate Zone Rating) and DWARF (Defensive Wins Above Replacement) quantify a player’s impact in the field.

Take Willie Mays: his career UZR of 194 and WAR of 84 underscore his defensive dominance in addition to his offensive firepower.

Similarly, Pedro Martinez’s 436 UZR contributed substantially to his 131 WAR as a pitcher, proving defense matters across positions.

3. Factor in Durability and Peak Performance

Durability can differentiate greats from great‑gunners. Track Games Played (G) and Plate Appearances (PA) per season to assess consistency.

Albert Pujols played 1,856 games over his first 20 seasons, averaging 1,100 PA per year—a benchmark for longevity.

Contrast this with a short‑career superstar like Edgar Martínez, whose 1,587 games still rank him 54th in all‑time games, but his peak WAR of 20 in 1992 remains unmatched.

4. Analyze Postseason Impact

A player’s clutch performance in the playoffs can cement their legacy. Look at Postseason WAR and clutch hitting metrics such as VORP (Value Over Replacement Player) in Game 7.

Jackie Robinson’s postseason WAR of 1.3 during the 1947 Giants run showcases his big‑stage contribution.

Modern icons like Shohei Ohtani have already posted 3.5 postseason WAR in a single season, a rarity among active players.

5. Weigh Intangibles with Qualitative Data

Leadership, sportsmanship, and influence on the game add depth to a ranking. Use primary sources such as Hall of Fame speeches, newspaper articles, and player interviews.

Consider how George Brett’s calm demeanor under pressure earned him the nickname “The Wizard,” while Barry Bonds’ controversial conduct remains a caveat in many all‑time discussions.

Assign a small “intangible score” (e.g., 0–10) to each player to quantify these softer attributes.

6. Create a Weighted Scoring Model

Assign weights to each metric—WAR (30%), OPS+ (20%), ERA+ (20%), UZR (10%), durability (10%), postseason impact (5%), intangibles (5%).

Multiply each player’s normalized score by the weight and sum the totals to produce an overall ranking score.

Test your model by checking if it places recognized legends like Babe Ruth, Hank Aaron, and Mike Trout near the top, ensuring the system’s validity.

7. Continuously Update and Re‑rank

Active players’ stats evolve each season. Schedule quarterly reviews to incorporate new data and adjust rankings accordingly.

Use tools like Baseball‑Reference and Fangraphs for up‑to‑date stats.

Remember, the goal is an informed, transparent list that others can scrutinize and debate.

Frequently Asked Questions

1. What is the most important stat to determine the best baseball players?

While many debates spotlight OPS and WAR as top picks, a holistic assessment incorporates OPS+ and ERA+ to normalize performance across eras.

Defensive contributions, captured by metrics like UZ (Ultimate Zone Rating) or DRS (Defensive Runs Saved), often tip the scales for players with comparable offensive output.

Actionable tip: When building a list, calculate a composite score: 0.4 × OPS+ + 0.3 × WAR + 0.3 × Defensive Metric. This weighted approach balances offense, defense, and longevity.

2. Did Babe Ruth play in the same era as modern players?

No. Ruth’s prime (1919‑1925) featured smaller ballparks and a “dead‑ball” era that produced lower ERAs.

Modern players face larger stadiums and advanced pitching staffs, so direct comparisons can mislead.

To adjust, use ERA+ = 100 × (League ERA ÷ Player ERA); Ruth’s ERA+ was 139, while a modern legend like Mike Trout hovers around 125 in recent seasons.

Actionable insight: Apply ERA+ or OPS+ when juxtaposing eras; ignore raw counts alone.

3. How many home runs did Hank Aaron hit?

Aaron’s career total is 755, a record that stood until 2007.

He finished 12th on the all‑time list as of 2026, having posted 44 home runs in his final season, 2021.

Comparatively, Aaron’s home run rate of 0.65 per plate appearance outpaces modern sluggers like Aaron Judge (0.66) and still ranks in the top five.

Actionable tip: Benchmark HR per plate appearance to account for career length differences.

4. Are there any current players who might join the all‑time greats list?

Mike Trout’s 1,300+ career hits and 4,500+ BABIP (Batting Average on Balls In Play) place him a few steps shy of the Hall of Fame threshold.

Shohei Ohtani’s dual role as pitcher and hitter, with a combined 45 WAR in 2023, showcases a rare modern versatility.

Other rising stars include Fernando Tatis Jr. (2024 WAR 8.0) and Trea Turner (2024 OPS 1.120).

Actionable insight: Track annual WAR and age‑adjusted performance curves for emerging players to forecast future rankings.

5. Does the Hall of Fame guarantee a player is among the best?

Induction signals a high career standard, yet some Hall members (e.g., Stan Musial) remain debated for “greatness” versus “greatness‑like.”

Conversely, players like Randy Johnson (Hall of Famer) rank lower in certain advanced metrics compared to non‑inducted peers.

Hall status reflects a consensus at the time, not an absolute measure of legacy.

Actionable tip: Use the Hall of Fame as a baseline, then layer in modern analytics for refined rankings.

6. What role does defense play in evaluating greatness?

Defensive excellence can add 10–15 runs per season, comparable to a full-time starter’s offensive contribution.

Players such as Brooks Robinson (DRS 436) and Ozzie Smith (DRS 286) showcase how defense can sustain a career’s overall value.

Fielding percentage alone is misleading; a range factor > 10.0 in the outfield often correlates with elite defensive range.

Actionable insight: Include a defensive weighting factor when constructing an all‑time list.

7. How does the introduction of sabermetrics affect classic player comparisons?

Sabermetrics normalizes for era, ballpark, and lineup protection, giving players like Jimmie Foxx (WAR 8.0) a clearer context versus modern sluggers.

Metrics such as wOBA (weighted On‑Base Average) account for run creation efficiency, allowing direct comparison of offensive output across decades.

Advanced defense metrics (e.g., Defensive Runs Saved) expose hidden value in players previously undervalued by traditional stats.

Actionable tip: Apply ERA+ and OPS+ when juxtaposing classic and modern players to avoid era bias.

8. Should postseason performance influence the greatest players list?

Postseason stats amplify a player’s legacy; Fred Lynn’s 15 postseason WAR in the 1980s remains unmatched.

A player’s clutch metrics—Runs Created (RC) in late‑game situations—can be a decisive factor in all‑time discussions.

Teams with consistent playoff success often built around such leaders, reinforcing the importance of postseason contributions.

Actionable insight: Track postseason WAR as a separate column; players above 10 postseason WAR should receive additional weighting in rankings.

Conclusion: Crafting Your Own All‑Time Baseball Ranking

1. Start with the Core Metrics

Begin by pulling the most widely accepted advanced stats for every era you’re considering.

WAR (Wins Above Replacement) – captures overall value; compare league averages of 2.0 in the 1920s to 4.5 in the 2000s.
OPS+ – normalizes on‑base plus slugging to league; 100 is league average.
ERA+ – for pitchers, a 140 indicates a dominant career.

Make a spreadsheet that lists these numbers side by side for your top candidates.

2. Apply Era Adjustments for Fairness

Ballparks, rules, and equipment have changed the game dramatically. Use League-Adjusted metrics to level the field.

Example: Babe Ruth’s raw 2.96 ERA actually translates to an ERA+ of 125 in the “Live‑Ball Era.”
Cy Young’s 3.25 career ERA becomes an ERA+ of 140 when adjusted to modern ballpark factors.

Don’t forget to factor in era-adjusted OPS when comparing hitters like Hank Aaron to Mike Trout.

3. Weigh Intangibles with Quantitative Proxies

Leadership, clutch performance, and defensive excellence can be quantified.

Use Clutch Hitting Index (CHI) – measures performance in high‑pressure moments.
Consider Defensive Runs Saved (DRS) or Ultimate Zone Rating (UZR) for outfielders and infielders.
Count postseason appearances and key moments (e.g., Ruth’s 1927 World Series home runs).

These proxies give you a data‑backed way to weigh intangible contributions.

4. Build a Personalized Ranking Framework

Create tiers that reflect your personal weighting of offense, defense, and legacy.

Tier A (1–5) – Players who dominate all three categories.
Tier B (6–10) – Players with peak offensive stats but moderate defense.
Tier C (11–15) – Players who excel in one area but fall short elsewhere.

Assign point values to each metric (e.g., WAR × 20, OPS+ × 1.5) and sum them to rank your players.

5. Validate Against Historical Consensus

Cross‑reference your list with established rankings: Hall of Fame selections, All‑Time Teams, and expert polls.

Check the National Baseball Hall of Fame roster for consistency.
Compare your top 10 to the Baseball-Reference All‑Time Team.

Discrepancies can spark deeper research into overlooked players.

6. Share, Debate, and Iterate

Upload your ranked list to a community forum or blog and invite feedback.

Use social media threads (Twitter, Reddit’s r/baseball) to spark discussion.
Solicit data points from other analysts to refine your methodology.

Remember, the goal is a living conversation, not a final verdict.

7. Keep Learning with Updated Analytics

New tools like Fangraphs’ Statcast and MLB’s Statcast Data emerge every season.

Track Exit Velocity and Hard Hit % for modern players.
Review Pitch Type and Velocity Logs for pitchers like Max Scherzer.

Incorporate these insights annually to keep your ranking current.

8. Final Thought: Your Ranking, Your Legacy

Deciding who are the best baseball players of all time is ultimately a blend of data, history, and personal passion.

Use the steps above to create a transparent, repeatable framework that others can evaluate and critique.
