DENVER (AP) — Troy Tulowitzki hit a three-run home run after No. 3 hitter Carlos Gonzalez was intentionally walked in front of him, Tyler Chatwood pitched seven strong innings for his first win of the season, and the Colorado Rockies beat the Philadelphia Phillies 12-1 Friday night.

Tulowitzki went 3 for 3 on the night, drove in five runs and drew a key walk during the Rockies’ four-run first inning. Drew Stubbs and Charlie Blackmon added three hits apiece. The 18 hits represented a season high for the Rockies and their run total matched a season high.

Chatwood (1-0), who missed the first two weeks of the season with a left hamstring strain, allowed one unearned run on two hits in his second start of the season and first at home.

Phillies starter Jonathan Pettibone (0-1) went four innings and allowed eight runs on nine hits.
