Two Colorado players -- outfielder Carolos Gonzalez and pitcher Roy Oswalt -- left Sunday's game against the Arizona Diamondbacks because of injuries.
Oswalt suffered a to a hamstring injury in the second inning while covering home after throwing a wild pitch.
The Rockies had signed Oswalt to a Minor League deal on May 2, and he made his debut with the Rockies on June 20.
It's not clear whether Oswalt will miss his next start. He is 0-3 with 7.88 ERA for Colorado this year.
Gonzalez injured the middle finger on his right hand when he fouled off a pitch in the ninth inning.
X-rays were negative, and Gonzalez is listed as day-to-day. He's hitting .303 with 24 homers.
