Changeup creates Coors advantage for De La Rosa

Rockies left-hander Jorge De La Rosa’s brown eyes burn with intensity. The scowl bubbles to the surface at times, like Wednesday night in the first inning when plate umpire Jeff Nelson called a ball on what De La Rosa thought was a good pitch to the Royals’ Billy Butler. Often, the batter buys into the intensity and his mind begins to expect the 92-95 mph fastball De La Rosa is capable of throwing.
