From Merriam-Webster:
Melky Cabrera in 2006 showed an on base percentage far above his typical performance. When Brady Anderson hit 50 homers in 1996 it was an anomaly.
Until Cabrera proves that he can do that on a consistent basis, I consider Melky Cabrera (or ANY rookie, take a look at MY historical post record if you don't believe me) suspect. Cabrera is no exception.
I also stand by my assertion that in another lineup he doesn't hit nearly as well. When you've got Melky Cabrera, Alex Rodriguez, Derek Jeter, Jason Giambi... etc in the same lineup, as a pitcher you're going to give him a LOT of good pitches to hit.
On the flip side, guys of All Star caliber (like the people surrounding Melky Cabrera) are given the green light in favorable (3-1, 3-0, 2-1, 2-0) counts. As a manager, I'm giving Melky the take sign every time because I want his ass on base for the big guys.
In Pittsburgh, he'd settle in with another bunch of crappy hitters and revert to his crappy hitting ways. Not that he was a tremendous hitter in the first place: he's still a corner outfielder with a .391 slugging percentage and a .748 OPS despite his above average OBP (for him).
