The Diamondbacks dropped their fourth straight, all at home, to fall to 2-13 at Chase Field this season.
Stubbs, who entered in a double switch in the eighth, hit a 2-2 pitch from Reed (0-2) into the right field seats for his first homer in 43 at-bats this year. Stubbs also chased down Eric Chavez’s drive in deep center to end the game.
“I was feeling good, but once again a terrible slider in the zone,” Reed said. “It was supposed to be down and away. I left it over the middle of the plate. He made me pay for it.”
“Coming in and facing their closer, one of their best guys in the back end of the bullpen, you just hope he makes a mistake and you get a good pitch to hit,” Stubbs said. “That last one was a slider out over the plate and I was able to put a good swing on it.”
Boone Logan (1-0) gave up Pollock’s homer but got the victory. LaTroy Hawkins allowed two hits in a scoreless ninth for his ninth save.
Colorado won its fourth series in a row.
Rockies starter Tyler Chatwood left in the sixth with tightness in his right elbow.
Tulowitzki also had a single and scored twice. In the first two games of the series, he is 5 for 6 with five RBIs and two home runs. He’s also walked three times, meaning he’s reached base in eight of his nine plate appearances.
Colorado’s Nolan Arenado had an RBI single to extend his hitting streak to 19 games, longest in the majors this season. Justin Morneau’s RBI triple extended his hitting streak to 13 games.
Trailing 3-2, Colorado took the lead with two runs in the sixth.
Carlos Gonzalez led off with a double to right, then Tulowitzki hit Mike Bolsinger’s 0-1 pitch into the swimming pool area beyond the right field fence to make it 4-3.
