You're not suggesting that leading the league in doubles, RBI, slugging and OPS at the age of 40 is unusual, are you? If anybody was going to age better than Mays, Aaron, Williams, Ruth, and Cobb it would be the guy released by the Twins.
I assumed he did. From the time he turned pro through age 32 he hit 49 homers in 13 seasons. Or less than four a year. From '99-00 he hit 30, including 20 in one season. His three highest doubles totals were from 32 to 34. Those years were peak PED years prior to testing.
I guess that could have been a coincidence or hard work. But it wasn't OPACY park effects, in both '99 and '00 he hit more homers on the road.
