PITTSBURGH -- Take Jhoulys Chacin out of Coors Field and he becomes one the best pitchers in baseball.
Chacin turned in another strong road effort Friday night, allowing one run in eight innings, to become a 10-game winner and pitch the Colorado Rockies to a 4-2 victory over the Pittsburgh Pirates in the opener of a three-game series at PNC Park.
Chacin allowed six hits, all coming in the first four innings, as he retired the final 14 batters he faced. Chacin struck out three and did not walk a batter.
In eight starts away from Coors Field this season, Chacin (10-5) is 4-2 with a sparkling 1.78 ERA as he has allowed nine earned runs in 50 2/3 innings. Chacin also holds the Rockies' single-season road ERA record of 2.44, which he set in 2010.
Chacin has pitched well everywhere lately, going 7-2 with a 2.11 in ERA in his last 10 starts since June 11.
Chacin helped Colorado bounce back from a nightmarish four-game series at Atlanta in which the Rockies were swept and outscored 40-13 by the Braves. The Rockies had lost 17 of their previous 23 road games, being outscored 123-60.
Rex Brothers held on for his eighth save in nine opportunities after allowing back-to-back doubles to Andrew McCutchen and Pedro Alvarez with one out in the ninth that enabled the Pirates to draw within 4-2.
Troy Tulowitzki homered and singled in the winning run for Colorado while Todd Helton hit a two-run single and Corey Dickerson had two hits.
Gerrit Cole (5-5) took the loss, giving up three runs and three hits in 5 1/3 innings with six strikeouts and two walks. In three of his last four starts, the rookie had pitched into the seventh inning.
Neil Walker and McCutchen both had two hits for Pittsburgh, which grounded into double plays in the second, third and fourth innings.
The Pirates have lost back-to-back games to begin August after entering the month with the best record in the major leagues at 65-42. They went a combined 37-78 from Aug. 1 on during the previous two seasons.
Dexter Fowler drew a leadoff walk, stole second base and moved to third on Dickerson's one-out single. Justin Wilson relieved Cole and allowed both inherited runners to score and was also charged with a run of his own as Tulowitzki's infield single brought home the go-ahead run and Helton followed with a two-run single.
The Rockies broke a 1-1 tie by scoring three runs in the sixth inning.
NOTES: Colorado LF Carlos Gonzalez was out of the lineup with a sprained right middle finger for the fifth time in the last eight games. Though the injury has been bothering Gonzalez for three weeks, the Rockies will not put Gonzalez on the disabled list. Instead, Gonzalez, who has hit 26 home runs this season, will try to play through the pain and the Rockies will give him maintenance days off to help manage the situation. ... Colorado RF Michael Cuddyer missed his second straight game to attend to a personal matter but is expected to return to the team Saturday. ... Pittsburgh activated RHP Jared Hughes from the 15-day disabled list and optioned RHP Vic Black to Triple-A Indianapolis. ... On Saturday night, Rockies LHP Jorge De La Rosa (10-5, 3.21) will face Pirates LHP Francisco Liriano (11-4, 2.16).
