Royals right-hander Ian Kennedy throws a curve, slider and changeup to go with his fastball. And he is one of the few pitchers on the team who throws only one kind of fastball -- a four-seam fastball. And there's a reason for that.
"I had a catcher with Arizona back [in 2011] who hated when I threw [a two-seamer]," Kennedy said, smiling. "He finally said, 'You need to junk that. It's terrible.' So I did. Since then I've thrown only four-seamers. Sometimes it might look like a two-seamer because it didn't come out right, but it's not.
