Yes, you can. When your reflexes improve and you start to tear the cover off the ball, pitchers will take a different approach with you. And then you have to be more selective at the plate.
Barry Bonds was great at getting on base before he used. But look at what happened to his OBP from 2001-2004.
.515 OBP
.582 OBP
.529 OBP
.609 OBP
How did that happen?
Sammy Sosa is an even better example. Before 1998, .340 was his best OBP. Then, all of a sudden it was .377, .367, .406, .436, .399.
