Hamilton has been the same exact hitter his entire career! I find it hard to believe any of you thought he resembled anything close to a 'patient' hitter (that's what it sounds like from the tone around here). And yes, like some have said, he's had these slumps before, and a few of them have been at the start of the season. Will he come around? Who knows, but his approach isn't any different from what it has been throughout his entire career.
For those of you that wanted him signed in the off-season, this shouldn't come as a surprise.
