By the year they turned 30 years of age here are some players statistics worth taking a look see.



Ty Cobb

He had a lifetime batting average of .370 when he hit 30 years of age. He finished with a mark of .367 when he retired.

Wade Boggs

Wade had a lifetime batting average of .356 when he turned 30 years of age. When he was done playing his lifetime average was .328

Joe Jackson

He had a .356 average and completed his career with a .358 average.

Ken Griffey Jr.

The Kid as he has been called had 438 home runs when he completed his season in his 30th year. That was year 2000. An average of 36.5 home runs per year in his first 12 seasons. He now has 536 home runs. He has averaged 18.6 home runs per year from 2001 to 2005. A shame what injuries can do. I think he had a chance to hit more home runs than Hank Aaron if he was injury free. Averaging 37 home runs a year from 2001 to 2009 would have put Ken at 771 home runs lifetime.

Lou Gehrig

By his 30th birthday he had 1285 Runs Batted In. That year was up to and including 1933. From 1934 to 1938 he had 709 RBIs. And in 1939 in eight games he had one more RBI. His falloff was not too severe after he turned 30. He averaged 141 RBIs in his last five full years of his career.

Mickey Mantle

Otis Nixon

Stole 515 of his 620 bases from the time he turned 30 to when he retired. The latter part of his career proved to be his most productive time. 83% of his stolen bases were swiped after he turned 30. When most players start to slow down, I guess he was revving up.
