DENVER _ Jorge De La Rosa continued his daytime dominance, and the Colorado Rockies put together just enough offense to edge the San Diego Padres 4-2 in the rubber game of their series Wednesday.
De La Rosa held the Padres to two runs in seven innings, getting a huge assist from catcher Yorvit Torrealba on an unusual double play that thwarted the Padres in the sixth.
Slumping Troy Tulowitzki drove in two runs with a double and a single, and Corey Dickerson went 3-for-4 with two doubles and a triple, two RBI and two runs scored.
De La Rosa (12-6) made his eighth daytime start and improved to 6-0 with a 1.58 ERA (51 1/3 innings, nine earned runs) in those games.
Torrealba's big play came with no out and runners on first and second after De La Rosa gave up successive singles to start the inning.
Logan Forsythe grounded to third baseman Nolan Arenado, who threw home, trapping Jedd Gyorko in a brief rundown. Torrealba tagged him out. Jesus Guzman tried to take third, a very bad decision when Torrealba ran toward the base and made a diving tag on Guzman before he reached it.
The Rockies completed a 5-1 homestand before beginning a 10-game road trip Friday. The Padres finished a 2-4 road trip before starting a 10-game homestand Thursday.
Andrew Cashner (8-7) gave up three runs while limiting the Rockies to six hits in seven innings with no walks and seven strikeouts.
He gave up a run in the first when Dickerson blooped an opposite-field double to left with two out. Tulowitzki, who entered the game with five hits in his previous 45 at-bats, followed with a double that was nearly caught by left fielder Logan Forsythe. He had the ball in his glove but lost it when he banged into the wall.
Chris Denorfia's two-out single in the third tied the game at 1, but the Rockies scored twice in their half of the inning. Dexter Fowler led off with a single, and Dickerson tripled him home. Tulowitzki followed with a single up the middle.
The Rockies gave closer Rex Brothers a two-run cushion with a run in the eighth. Fowler led off with a single and stole second. Another opposite-field bloop double by Dickerson brought him home.
Brothers retired the side in order in the ninth for his 11th save.
With a run in the fourth, the Padres cut the Rockies' lead to 3-2. Jedd Gyorko doubled off the wall in right with one out, and scored when Guzman followed with a single.
