DENVER -- The Colorado Rockies slowly picked away at Pittsburgh Pirates starter Jeff Locke Saturday night, driving three solo home runs out of Coors Field on their way to an 8-1 win.
Locke struggled with his command, giving up six earned runs on 10 hits, but was not aided at all by the offense, which avoided a shutout for the second game with a run in the ninth inning on an Ike Davis pinch-hit homer.
The Pirates struggled to produce with Rockies left-hander Tyler Matzek on the mound. Matzek put down the Pirates in order in the first and third, only once allowed two baserunners and held the Pirates to just three hits in seven innings.
Jeanmar Gomez gave up two more runs in the eighth when Josh Rutledge dropped in a two-run single.
Pirates manager Clint Hurdle shuffled the lineup in an effort to create a spark after an 8-1 loss Friday night, bumping Josh Harrison to the leadoff spot and dropping Gregory Polanco down to the No. 7 spot.
He also shifted Jordy Mercer (1 for 3, hit-batsman) to the No. 2 hole, but there was little production anywhere in the lineup.
The Pirates stranded runners in the second, fourth and fifth and went 0 for 4 with runners in scoring position.
The Pirates put two on in the seventh, but Brent Morel grounded into a double play to end the best chance to score.
The loss drops the Pirates to 54-49.
Locke finished at 62/3 innings, giving up five runs on 10 hits, three of which were home runs. He walked three (one intentionally) and struck out six.
Matzek went seven innings, giving up just three hits. He walked two and struck out three.
The Rockies got started in the third when Rutledge stroked an RBI single to put the Rockies up 1-0.
He drove in Charlie Blackmon, who had reached second on a throwing error by Mercer then stole third.
Matzek singled to lead off the inning.
Blackmon hit a sharp ball to Gaby Sanchez who threw to Mercer to get the lead runner at second. Mercer fired back, but Sanchez hadn't recovered and Locke hadn't reached the bag yet.
Mercer's throw, which was on target, sailed past an empty first base allowing Blackmon to take second.
Mercer opened the fourth with a double and advanced to third on a groundout but was stranded.
Locke gave up a home run to Drew Stubbs on a 93 mph fastball to open the fourth, but put down the next three batters.
Russell Martin walked to open the fifth. Polanco reached on a fielder's choice when he roped one toward the hole between short and third as Nolan Arenado made a diving catch and threw out Martin at second. Polanco was eventually stranded.
The Rockies extended their lead to 4-0 in the fifth when Nolan Arenado hit an RBI single and Corey Dickerson hit an RBI groundout with the bases loaded.
Locke was visited on the mound by pitching coach Ray Searage with two outs and induced a fly-ball out to get out of the inning.
He gave up solo shots to Arenado and Dickerson in the seventh before Hurdle went to his bullpen.
According to Elias Sports, the Rockies' five extra-base hits in the seventh inning Friday night tied for the most extra-base hits by a team in a single inning this season.
It also was the first time Colorado did that since September 2012.
