Turning point: Ubaldo Jimenez pitched 5 2/3 hitless innings, walked Alex Romero and Stephen Drew in succession and gave up a three-run homer to Mark Reynolds on a 1-2 pitch that tied the game at three in the sixth. The Diamondbacks scored what proved to be the winning run in the seventh when Gerardo Parra led off with a single, pinch hitter Tony Clark walked with one out and Parra stole third base as Jimenez was pitching to Felipe Lopez, who singled.

At the plate: The Rockies, who have lost consecutive games at home for the first time since they were swept in three games by the Dodgers on May 26-28, leading to the May 29 firing of manager Clint Hurdle, scored two runs with two out in the third when Jimenez was safe on an infield single and Seth Smith reached base when his ground ball went through first baseman Chad Tracy, an error that allowed Jimenez to reach third base. He scored on Ryan Spilborgh’s single, which pitcher Dan Haren deflected, and Todd Helton, who went 2-for-4 with a double, followed with a run-scoring single. …Troy Tulowitzki homered with two out in the fourth, his 13th of the year. …The Rockies did not have a hit after pinch hitter Dexter Fowler opened the seventh with a single. …Reynolds’ home run was his 24th of the season. …The Diamondbacks won two straight for the first time since June 17-18.

On the mound: Jimenez allowed more walks (5) than hits (4) in 6 1/3 innings. His eight strikeouts were one shy of his season high; he had nine strikeouts June 7 at St. Louis while pitching eight innings. Jimenez entered the game with a 14-inning scoreless streak against the Diamondbacks and extended it to 19 innings before Reynolds’ homer in the sixth. He has lost his past two decisions and has gone three starts since his last victory June 18. …Alan Embree relieved Jimenez with one out and runners on first and second and got Romero to ground into a double play. …Juan Rincon worked a scoreless eighth, stranding two runners who reached on a walk and second baseman Ian Stewart’s error. …Haren, who has won four of his past five starts, allowed three runs, one earned, in six innings to lower his National League-leading ERA to 2.16. …Left-hander Scott Schoeneweis came on to face Helton with two out and a runner on third in the seventh and struck him out. Schoeneweis was one of four Arizona relievers who combined to allow one hit and no runs in three innings.

Numbers game: 5 home runs allowed by Jimenez in 109 2/3 innings. The other four came with the bases empty.

He said it: “The pitch that he threw to Reynolds is the correct pitch. It just wasn’t high enough.”
