Babe Ruth is the correct answer and there is no room for debate. He was just too much better than everyone else he played against to not choose him. He posted 10 seasons with a WAR above 10 (Pujols, easily the most dominant player currently, has done that once. Bonds* had 7 such seasons) and led the league in WAR 2 other seasons! He also lost about 3 seasons worth of ABs due to being a pitcher and another season playing in the dead ball era (1919, when he only hit 29 HRs instead of 50+ that he hit the next 2 years). Safe to say he lost at least 50 HRs which would put him above Bonds. There have only been 34 single season SLG% posted not by Ruth that have been higher than his career .690 mark, his .474 OBP is 100 points higher than Hank Aaron's .374 career mark. He set the single season HR mark 4 different times and hit more HRs in 1927 than any other team in the AL. He also posted the greatest single season of all-time in 1921 going .378/.512/.846 177 R, 204 H, 145 BB, 44 2B, 16 3B, 59 HR, 171 RBI, 457 TB. And there is the pitching too. In 1916 (at age 20) he was the second best pitcher in the AL behind only Walter Johnson (the greatest pitcher of ALL-time). He has the record for the longest ever pitched World Series game while giving up 1 R in a 14 inning CG in 1916. His other 2 World Series pitching performances are a SHO and an 8 inning, 2 ER win. His 0.87 World Series ERA in 31 IP is 4th best all-time. If you discount Bonds*, Pujols (too early, will have a decline) and Negro leaguers (not enough data) the next best hitters are Williams and Gehrig and you could have an argument for next best player between Cobb, Mays, Wagner, Williams, Musial, Gehrig, Aaron, Dimaggio, Speaker or Hornsby. Position by position you could argue any of these top tier guys could represent their position: C: Bench, Berra, Gibson 1B: Gehrig, Foxx, Greenberg, Pujols, McGwire 2B: Hornsby, Collins, Morgan 3B: Schmidt, Mathews, Brett SS: Wagner, Rodriguez LF: Williams, Musial, Henderson, Bonds CF: Cobb, Mays, Speaker, Dimaggio, Mantle RF: Ruth RF2: Aaron, Robinson, Clemente I would go: 1) Cobb CF 2) Hornsby 2B 3) Williams DH 4) Ruth RF 5) Gehrig 1B 6) Musial LF 7) Rodriguez SS 8) Schmidt 3B 9) Bench C
