De La Rosa to miss start with groin injury; return unclear

SCOTTSDALE, Ariz. -- Rockies left-hander Jorge De La Rosa expects to miss his next start and is not sure how long his injured left groin will keep him off the mound.

On Friday, De La Rosa exited his Cactus League debut after 2 1/3 innings against the A's after aggravating the tightness in his left groin. It's the same injury that caused him to miss his first two scheduled Cactus League starts.

De La Rosa, who has pitched in a "B" game this spring, threw 45 pitches and gave up two runs on three hits in the outing. He expects to receive the results from the MRI on his groin Monday.

"I might miss the next two starts, I don't know," De La Rosa said. "It's really sore right now. I know I'm not going to throw for a few days because I can feel the pain."

It's unclear if De La Rosa's injury will keep him from starting the April 10 home opener against the Cubs. He is receiving treatment and expects to know more next week.

"We still have a little time before he's throwing [side sessions]," Rockies manager Walt Weiss said. "We are assessing him every day. It could be worse with him."
