My picks follow. Names of left fielders I have seen live (on TV and/or in the stadium) are bolded, while earlier players were seleced on the basis of reputation.
Barry Bonds – My heart said “no”, but my head decided that the all-time home run leader deserves a place on the list, even though his fame is synonymous with infamy in many people’s estimation
Lou Brock – NL’s all-time steals leader trails only Henderson on the overall list, and is also a member of the 3000-hit club
Ed Delahanty – His career BA of .346 is fifth-best of all time, and he hit over 100 home runs during the dead-ball era
Rickey Henderson – All-time stolen base leader for both a single season (130) and career (1406)
Shoeless Joe Jackson – His Black Sox membership can’t be denied, but neither can his .356 average (third-best ever) nor the admiring accounts of those who saw him in action
Joe Medwick – His Triple Crown in 1937 is still the NL’s most recent, and he hit at least 40 doubles per season from 1933 to '39, an unmatched record of consistent excellence in that department
Stan Musial – National League’s all-time hit leader when he retired, with his 3630 safeties divided absolutely equally between St. Louis home games and road contests
Lefty O’Doul – His .349 lifetime average is the fourth-best ever, and he also gained fame as a manager in the Pacific Coast League when that circuit was considered the “third major league” in the pre-expansion era
Al Simmons – The right fielder on Harry Stein’s All-Time Polish All-Star Team, Aloysius Szymanski hit at least .308 (while also knocking in at least 102 runs) in each of his first eleven big-league campaigns
Ted Williams – Last man to hit .400 or better while qualifying for the batting title, he compiled a .344 lifetime average while smacking over 500 home runs and losing playing time while serving in both WWII and the Korean War
