When it comes to veteran left-hander Jorge De La Rosa, the Rockies can never be too careful. The club scratched De La Rosa from his scheduled Cactus League start against the Padres on Saturday night because of tightness in his left forearm. However, trainer Keith Dugger said the move was precautionary and De La Rosa is scheduled to pitch two innings in a minor-league game Sunday. The tightness occurred after De La Rosa's start last Monday, forcing him to push his bullpen session back a day. Right-hander Jeff Manship, who pitched for the Twins from 2009-12, started Saturday's game in De La Rosa's place. Though De La Rosa called the tight forearm "no big deal," it bears watching. He had Tommy John elbow surgery in June 2011 and forearm tightness arose last season as he began throwing again.
