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 and the 1-2 hitters in the Rockies' batting order combined to score five of Colorado's runs. 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. Chatwood struck out six and walked one.
Phillies starter Jonathan Pettibone (0-1) went four innings and allowed eight runs on nine hits.
He was in trouble from the outset, giving up four runs in a 36-pitch first inning. Blackmon and Stubbs each singled to start the inning. Gonzalez was robbed when second baseman Chase Utley leaped high in the air to catch his sharply hit line drive, but Tulowitzki worked a walk to load the bases in a 14-pitch at-bat that included 10 foul balls, eight with the count full.
Justin Morneau followed with a two-run double. Wilin Rosario had a run-scoring groundout and Nolan Arenado singled up the middle to drive in the Rockies' fourth run.
It didn't get any better for Pettibone in the second as Blackmon singled and was sacrificed to second. The Phillies opted to intentionally walk Gonzalez, a lifetime .395 hitter in 23 previous games against Philadelphia, and go after Tulowitzki. He responded by driving an 0-1 offering into the stand of evergreens beyond the center field wall for his second home run of the season, upping Colorado's lead to 7-0.
The Rockies went up 8-0 on Tulowitzki's run-scoring double in the fourth, before the Phillies got on the scoreboard in the fifth. After Carlos Ruiz reached on third baseman Arenado's two-out fielding error, Cody Asche singled to center for the Phillies' first hit of the game and pinch hitter Jayson Nix, batting for Pettibone, singled to score Ruiz.
Colorado got that run back on Tulowitzki's RBI single in the sixth.
