PHILADELPHIA - By the time Cole Hamels rushed off to be with his pregnant wife, his streak of postseason dominance was long over.

Yorvit Torrealba hit a two-run homer, Aaron Cook pitched effectively into the sixth inning and the Colorado Rockies beat Hamels and the Philadelphia Phillies 5-4 Thursday to even their NL playoff series at a game apiece.

Huston Street pitched out of trouble in the ninth to secure the win for Colorado. He retired Shane Victorino on a soft liner to second to leave the potential tying run — Game 1 winner Cliff Lee — at second base.

“It was definitely a huge game for us,” Cook said. “It’s huge to go back home with the series tied.”

Hamels, the World Series and NLCS MVP last year, looked nothing like the guy who was brilliant during Philadelphia’s championship run last October. The left-hander allowed four runs and seven hits in five innings. He didn’t stick around after being pulled for a pinch hitter, heading to the hospital to join his wife, Heidi, who was in labor with the couple’s first child.

Was Hamels distracted on the mound?

“It could’ve bothered him, yes,” Phillies manager Charlie Manuel said. “He was concerned about his wife and his child. It’s an exciting time, something you look forward to. It was probably on his mind.”

The best-of-five series shifts to Denver for Game 3 on Saturday. Jason Hammel (10-8) will start for the wild-card Rockies against a yet-to-be-announced pitcher. Manuel said he’ll use Joe Blanton or Pedro Martinez. J.A. Happ was a candidate before getting injured.

Blanton pitched one inning in relief, allowing a run. Happ got knocked out of the game when Seth Smith hit a hard liner off the lower part of his left leg. X-rays were negative.

“He was trying to stay out there, but he wasn’t able to pitch,” Manuel said. “I think he’ll be fine.”

Making his third start since a shoulder strain sidelined him for most of September, Cook allowed three runs and seven hits in five-plus innings. The right-handed sinkerballer got 12 of his 15 outs on grounders or strikeouts.

“His sinker was downhill and he was really working both sides of the plate,” Torrealba said.

After Lee turned in a masterful performance in his playoff debut Wednesday, the Phillies were counting on Hamels to give them a commanding 2-0 series lead. But Hamels hasn’t been the same pitcher since going 4-0 with a 1.80 ERA in five postseason starts last year. He was 10-11 with a 4.32 ERA this year, and now is 0-7 in day games.

“His stuff was good,” Manuel said. “He threw some close pitches. He was around the plate. His command could’ve been better.”

The Phillies are trying to become the first repeat champions since the New York Yankees won three World Series in a row from 1998-2000. No NL team has done it since the Cincinnati Reds in 1975-76.

For the second straight day, the Phillies had the largest crowd in the six-year history of Citizens Bank Park. There were 46,528 fans packed in the ballpark, waving their white-and-red “Fightin’ Phils” towels. Now, there’s no guarantee they’ll see another game this year.

Jayson Werth’s solo homer off Rafael Betancourt in the eighth got the Phillies within a run and whipped the fans into a frenzy.

But Franklin Morales came in and retired Raul Ibanez on a sharp grounder. Street, who was 35 for 37 in save chances in the regular season, started the ninth.

He walked pinch-hitter Matt Stairs with one out. Lee, who became the first Phillies pitcher to steal a base in the postseason in Game 1, ran for the slow-footed Stairs. After Miguel Cairo flied to right, Jimmy Rollins singled to right. But Street got Victorino to end it.

“It’s huge,” Torrealba said. “Going back to Denver, that was our goal, if we can win at least one game here — and we did.”

Trailing 4-0, the Phillies finally got going in the sixth. Victorino led off with an infield single and advanced to second on second baseman Clint Barmes’ throwing error. Chase Utley followed with a single and Ryan Howard lined an RBI double into the right-field corner, chasing Cook.
