DENVER — Ubaldo Jimenez threw eight shutout innings, Seth Smith homered twice and the Colorado Rockies beat the Arizona Diamondbacks 7-3 on Wednesday night.
Jimenez (9-1) continued his dominant start to the season, extending his current scoreless streak to 16 1-3 innings and dropping his ERA to 0.88, the best in baseball. His nine wins lead the major leagues.
The crowd of 26,320 gave him an ovation as he walked off after striking out three and walking one.
Carlos Gonzalez also homered and Miguel Olivo had three hits for the Rockies, who have won a season-high four straight.
Mark Reynolds hit his 12th home run and Gerardo Parra had two hits for the Diamondbacks, who have lost three in a row.
It looked like Jimenez might need all the run support he could get in the first few innings. The Diamondbacks were hitting Jimenez, they just couldn't cash in on their opportunities. Their best chance came right away.
Kelly Johnson led off the game with a double. With two outs, center fielder Carlos Gonzalez had to make a running catch at the wall to retire Stephen Drew.
Arizona had runners on in the second and third innings but Jimenez kept the Diamondbacks off the board.
Smith homered with one out in the first to give the Rockies a 1-0 lead.
Gonzalez led off the third with a walk and stole second. After Lopez retired the next two batters, Troy Tulowitzki walked and Brad Hawpe followed with a triple to right-centerfield to make it 3-0.
The Rockies added another run in the sixth when Tulowitzki led off with a double and scored on Olivo's single to right in Rodrigo Lopez's last inning.
Lopez (2-3) gave up four runs and five hits, struck out three and walked four.
Gonzalez and Smith greeted reliever Juan Gutierrez with back-to-back homers to lead off the seventh and made it 6-0. It was the second time this year the duo has hit consecutive homers.
Ian Stewart's RBI single with two outs scored Tulowitzki from second to make it 7-0.
Reynolds hit a three-run homer off Rafael Betancourt in the ninth.
