Who has the highest batting average for their final season in Major League Baseball?

Answer 1

That was Joe Jackson who hit .382 in his final season with the Chicago White Sox in 1920. Jackson was one of the eight players that formed the 'Black Sox' that were expelled from MLB for supposedly throwing the 1919 World Series. He was 32 years old in his final season. I went through some Hall of Famers to see what their final season looked like. I did this to see what the players were hitting when they were somewhat older, since Jackson was only 32 in his final season. The players listed below each were on the roster of their team for most of the, if not the entire, season and had at least 300 at bats. Many of the Hall of Famers hit over .300 in their final full season but hung on as backups for one or several seasons afterwards playing just a few games or became managers and played only when someone was injured. I found 8 Hall of Famers that hit .300+ in their final season where they had at least 300 at bats. 1) Ty Cobb - .323 (114 hits in 353 at bats at age 43)

2) Ted Williams - .316 (98 hits in 310 at bats at age 41)

3) Kirby Puckett - .314 (169 hits in 538 at bats at the age of 35)

4) Roberto Clemente - .312 (118 hits in 378 at bats at age 37)

5) George Sisler - .309 (133 hits in 431 at bats at age 37)

6) Richie Ashburn - .306 (119 hits in 389 at bats at age 35)

7) Ross Youngs - .306 - (114 hits in 372 at bats at age 29 ... Youngs was diagnosed with a kidney disorder called Bright's Disease which cut his career short. He passed away a year after his final season in MLB at the age of 30)

8) Lou Brock - .304 (123 hits in 405 at bats at the age of 38)
