DENVER -- The Colorado Rockies had been waiting for a game like this, a game where they could flex their offensive muscle by scoring early.
They did just that Friday night, beating the Milwaukee Brewers, 8-3. The Rockies scored four runs in the second and four in the fourth, which was more than enough for Tyler Chatwood, given the way he has pitched this season.
Chatwood (7-3) held the Brewers to two runs and six hits in seven innings while throwing a season-high 106 pitches, 73 for strikes. He set a career-high with 11 strikeouts and didn't walk anyone as he lowered his ERA to 2.48 and allowed two or fewer runs for the 12th time in his past 13 starts.
"His breaking ball was filthy," manager Walt Weiss said. "His curveball was sharp. His fastball was explosive and down. He's got that slider that he has a lot of confidence in. He was really good."
Chatwood doubled home two runs in the second and singled in the fifth, going 2-for-2 with a sacrifice and raising his average to .345 (10-for-29) with seven RBI. His double was the only extra-base hit for the Rockies, who also had eight singles.
The Rockies entered the game with a National League-low 58 runs in their previous 20 games in July, scoring three or fewer runs in 14 of them..
"Balls fell for us, and we were able to string multiple hits together, which has been tough for us," Weiss said. "It was nice to have a big inning. We haven't done that in a little while.
The victory left the Rockies 4-4 on their 10-game homestand to open the second half.
The Brewers got their first runner to second base when Rickie Weeks led off the sixth inning with a double and scored on Norichika Aoki's single. Aoki eventually scored on a Logan Shafer ground out.
The Brewers scored a run in the ninth when cleanup hitter Carlos Gomez belted his 17th homer off Manuel Corpas.
Brewers starter Wily Peralta had gone 2-0 with an 0.31 ERA in four previous starts this month.
"It was a tough outing, man," Peralta said. "A lot of fastballs up in the zone. The starts before I was doing good because I was able to keep the fastball down."
Colorado loaded the bases with no outs in the second. Arenado's infield hit drove in the first run, and Chatwood bounced a two-run double inside third base. After Dexter Fowler was hit with a pitch to load the bases again, DJ LeMahieu grounded into a run-scoring fielder's choice.
The Rockies loaded the bases with one out in the fourth on singles by Charlie Blackmon and Arenado and a walk to Fowler. LeMahieu again grounded into a run-scoring fielder's choice.
Brewers manager Ron Roenicke, who was a coach with the Los Angeles Angels where Chatwood got his start, sees a big difference in the Rockies starter.
"His fastball's the biggest difference," Roenicke said. "Then his fastball was really straight. Always had a great arm. Was not always 95 but really straight. He's got really nice movement on his ball now. Pitches to both sides. He's always had a really good curveball. He's come up with a nice tight slider now. And he mixes in the changeup.
"You look at his stats and they're kind of a little strange because the hits (81) and innings (83 1/3) are pretty close, but the ERA is so low. But when people get on base, he's really doing a nice job to have them not score off him."
NOTES: Rockies LHP Drew Pomeranz was placed on the 15-day disabled list retroactive to July 23 with left bicep tendinitis. OF Corey Dickerson was recalled from Triple-A Colorado Springs to take Pomeranz's spot on the roster. This is Dickerson's second stint with the Rockies. In 15 games between June 21 and July 10, he hit .212 with four doubles and two RBI. ... RHP Collin McHugh will be activated Saturday to start in place of Pomeranz and a corresponding roster move will have to be made. McHugh, 26, is 3-0 with a 3.18 ERA in three starts for Triple-A Colorado Springs. The Rockies acquired him June 18 from the New York Mets in a trade for OF Eric Young Jr. McHugh will be the ninth pitcher to start this season for the Rockies. ... Rockies LF Carlos Gonzalez was not in the lineup due to soreness in his right middle finger. On his first swing Thursday, he aggravated the finger, which he sprained July 7 and left the game after the third inning. Gonzalez is day-to-day and manager Walt Weiss doesn't think Gonzalez will have to go on the disabled list. ... The Brewers selected the contract of Rob Wooten from Triple-A Nashville where he went 0-1 with 20 saves and a 2.94 ERA in 40 games. Wooten, who made his major-league debut on Friday, takes the roster spot of 1B-OF Sean Halton, who was optioned to Nashville on Thursday.
