DENVER — Jhoulys Chacin pitched effectively into the seventh inning and became the first Rockies starter to throw 100 pitches in a game since last June before leaving with an injury as Colorado beat the Arizona Diamondbacks 3-1 Friday night.
Troy Tulowitzki hit a two-run homer and Chacin helped himself by driving in a run with a sacrifice fly as the Rockies won their seventh in row and remained unbeaten in seven home games this season.
Chacin (3-0) was seen grabbing his lower left back after throwing his fourth pitch to Arizona's Cody Ross with one out in the seventh inning. He was taken out of the game after a conference near the mound with manager Walt Weiss and team trainers and replaced by reliever Wilton Lopez.
The last time a Colorado starter reached the century mark in pitches was last June 12, a stretch of 117 games.
