Look at Gardner's history before making that comment. He'd hit around .300 at his level, get promoted mid season, then slump at the new level. The following yr, he'd hit over .300, get promoted, then slump at the new level. This is the first yr he has started for the whole yr.
2006- A+ Tampa- .323/.433/.418
2006- AA Trenton- .272/.352/.318
2007- AA Trenton- .300/.392/.419
2007- AAA Scranton- .260/.343/.331
2008- AAA Scranton- .296/.414/.422
2008- MLB New York- .228/.283/.299
See the trend here? He takes awhile to get comfortable, but when he does, he's a .300 hitter who gets on base in the upper .300 range. Last yr was a platoon situation and just as he was heating up, he broke his thumb. This is the first season that he has been handed a starting job and he ran with it, like he did throughout hit MILB career
