PITTSBURGH (AP) - Jorge De La Rosa has been struggling lately as he had his second poor start in a row.
De La Rosa lasted only four-plus innings Saturday night as Francisco Liriano continued his recent dominance with seven strong innings, and Jose Tabata homered and drove in two runs to lead the Pittsburgh Pirates to a 5-2 win over the Colorado Rockies on Saturday night.
De La Rosa (10-6) gave up three runs on six hits while striking out three and walking two. That came five days after he gave up a season-high eight runs in a loss to the Braves at Atlanta.
``Jorge didn't have very good command,' Colorado manager Walt Weiss said. ``It was a struggle for him from the start. He's just having a little tough time right now, he'll be fine.'
De La Rosa had given up three runs or less in each of his nine starts before getting pounded by the Braves and, despite his struggles, allowed just three runs on Saturday.
``He is a pitcher who has what is often premier-type command,' Pirates manager Clint Hurdle said. ``I've seen it before. We just happened to catch him on a night when his command wasn't as good as usual and our guys did a good job with their approach against him. Normally, though, he's a pitcher who will challenge your plate discipline and your patience.'
De La Rosa has been bothered by a sore thumb on his pitching hand recently but both he and Weiss said the injury was not a factor.
Liriano (12-4) allowed only two hits to offset his five walks and had six strikeouts. The left-hander improved to 7-1 with a 1.65 ERA in his last eight starts for the NL Central leaders.
Last season, Liriano was a combined 6-12 with the Minnesota Twins and Chicago White Sox. He has a hard time explaining his turnaround, which is a big reason why the Pirates hold a 1 1/2-game lead over St. Louis in the NL Central.
``What can I say?' he said. ``Everything is going good for me and good for the team. I'm not really thinking about it too much. I'm just going out and pitching and trying to be aggressive and get people out. It's working out well for me and it is working out for well for the team because we're winning.'
Tabata hit his first home run since May 11 - a span of 112 plate appearances - and also tripled while going 3 for 4 to raise his average to .266. Tabata has hit just three homers this season, which is why general manager Neal Huntington tried to trade for an outfielder before the July 31 non-waiver deadline, though without success.
The Rockies put men on base in six of Liriano's seven innings but they went 0 for 9 against him with runners on, including five hitless at_bats with runners in scoring position.
Colorado lost for the fifth time in six games.
``We had some opportunities early but like most of the good ones once he settled in he was tough,' Weiss said. ``He had a good changeup and his command was pretty good even though he walked some guys.'
Gaby Sanchez had two hits and two RBIs for Pittsburgh, while Jordy Mercer and Andrew McCutchen added two hits each.
Fill-in closer Mark Melancon, a native of Arvada, Colo., a Denver suburb, pitched a 1-2-3 ninth for his sixth save.
The Pirates scored one run each in the third through seventh innings to take a 5-0 lead.
In the third, Starling Marte led off with a single, stole second, took third on Jordy Mercer's groundout and scored on McCutchen's double. Tabata led off the fourth by homering over the 375 sign in right-center for his third of the season.
Sanchez hit run-scoring singles in both the fifth and seventh innings, while Tabata led off the sixth with a triple and scored on Josh Harrison's squeeze bunt.
Colorado finally scored a pair in the eighth on consecutive RBI singles by Troy Tulowitzki and Michael Cuddyer, who returned to the team after missing the previous two games because of a family emergency.
