PHILADELPHIA -- Jorge De La Rosa was again solid on the mound for the Colorado Rockies. But his latest victory hinged in part on a phantom tag by first baseman Todd Helton.
De La Rosa (13-6) won his third straight start Tuesday night as the Rockies claimed a rare road victory with a 5-3 win over the Philadelphia Phillies.
De La Rosa pitched 6 1/3 innings and allowed three runs (two earned) and three hits. He struck out three and walked three while beating the Phillies for the first time in five career decisions.
"Finally," he said. "Finally I win one game from them. They're a tough team for me. I'm glad I beat them today."
Rockies manager Walt Weiss said, "He's done it all year. He's been our guy."
Troy Tulowitzki and Wilin Rosario homered for the Rockies, who had lost three straight, all on the road. They had dropped 12 of their previous 14 away from home and 14 of 20. Colorado is 23-41 on the road this season.
The Phillies lost for the third time in five games under interim manager Ryne Sandberg, who replaced the fired Charlie Manuel last Friday.
"It was a quiet night offensively," said Sandberg, whose team finished with three hits.
Asked if he plans to shake up his lineup, he said, "There are not too many options. All the guys have a chance to be out there."
Philadelphia put the tying runs aboard in the seventh, but with two outs, Colorado third baseman Nolan Arenado made a spectacular backhand play on Jimmy Rollins' smash down the line, then executed a one-hop throw to Helton at first base. Helton, who was celebrating his 40th birthday, ranged off the bag to gather the ball, and first base umpire Jim Wolf ruled that he tagged Rollins.
Neither Rollins nor Sandberg argued the call.
"Jimmy said he felt something on his back," Sandberg said.
That was news to the Rockies.
"I saw the replay and he was obviously safe," Arenado said. "Todd sold it well."
Helton said, "I don't know if you call it selling it. Just my natural reaction is to think I tagged him, even though it didn't work out that way."
In the eighth, Colorado reliever Rex Brothers was twice called for balks, allowing Domonic Brown to advance from first to third. However, Brothers struck out Michael Young to end the threat.
Weiss said the umpires told him that Brothers was not coming to a complete stop in the stretch.
"I think he's been borderline at times (this year)," Weiss said, "but nobody's called it. It's tough to interpret it. They saw him rolling through his stop."
Rafael Betancourt pitched a scoreless ninth for his career-high 16th save in 17 opportunities.
Philadelphia's Tyler Cloyd, recalled from Triple-A Lehigh Valley to make his first major league start since June 12, worked six innings, allowing five runs and eight hits. Cloyd (2-3), who struck out six and walked one, fell to 0-4 in five career starts at Citizens Bank Park.
Tulowitzki hit his 22nd homer, a two-run shot, as part of a three-run first inning. It was his second homer in as many nights.
Colorado's Dexter Fowler, who went 2-for-3 with two walks, tacked on an RBI single in the second, and Rosario's solo homer in the third made it 5-0.
The Phillies struck back with three runs in their half of the third. The first came home on Helton's first error since June 2012. Chase Utley also drove in a run with a single and Brown added a sacrifice fly.
