Apr 5: Catcher A.J. Pierzynski (White Sox) spent mornings at his locker in spring training playing with his Nintendo DS, but he did it for a reason. Pierzynski has been working with a vision-training game for his handheld, with the hope of improving his ability to pick up the baseball. So far, the reviews are good, considering he has two home runs, a .529 batting average and a team-high seven RBI through four games.
Whether playing the Nintendo DS is really helping him see the ball better is probably up for discussion, but if this story starts to circulate and A.J. continues to hit even .350 by the end of April, you'll definitely see a lot more DS handhelds in MLB locker rooms, err, "clubhouses".
