Ryan Klesko
Padres

Klesko warned us prior to last season -– the Padres' new Petco Park was not to his liking. He then proved it by hitting a career-low nine homers. But he's already matched that total this season. Why the turnaround? The left-handed slugger spent the offseason regaining the strength in his shoulder that had been zapped the previous year following surgery. And he's driving more balls toward left-center -- which at Petco is 20 feet shorter than right-center.
