Homering off of Clemens

Cameron Maybin hit his first big-league home run yesterday, and it was off Roger Clemens (then he got his first big-league hit by pitch in his next at bat). Clemens had 40 Major League wins before Maybin was born. Maybin, at 20 years old, could still be playing in the year 2027.

Reggie Jackson started his career in 1967. Reggie hit a couple of home runs off Clemens. That could be 60 years in between when Reggie started and Maybin finishes. (That probably is not a record for such a thing. It could be about 10 years longer, but I didn't feel like figuring it out).
