It isn't the 1990s anymore in terms of being able to smack 40 dingers on roids until you're 40.
It's really, really hard to stay on top of the massive velocity of today's pitchers past your mid-30s and almost nobody except Nelson Cruz has managed to be a a quality hitter past age 35 in recent years. Looks like Paul Goldschmidt might manage the same.
So far this year, Goldschmidt looks like he's as cooked as Abreu.
