Once again, inappropriate use of BABIP. He is trying to hit the ball on the ground. His BABIP should be high. When he makes contact, he is trying to hit the ball on the ground. His stats bear that out. In 2008, his GO/AO was 0.98. In 2009, it was 1.11. In 2010, it is 1.46. Also helping his BA is a drop in K rate. He's dropped from 16% from 2009 to 12%. Here are some guys who are comparable in speed to Gardner and their BABIP
Crawford .331 career BABIP
Ichiro .357 career BABIP
Ellsbury .328 career BABIP
Putting the ball in play + elite speed is great. Now, .384, probably not sustainable. But he will never drop to below .300
