LOS ANGELES -- Luis Cruz wasn't a significant piece of the Los Angeles Dodgers' roster until third baseman Jerry Hairston Jr. went down for the rest of the season in mid-August with inflammation in his left hip. Since then, the four-year veteran has done more than his share to help keep his team in the postseason hunt.
Cruz greeted St. Louis reliever Edwin Mujica with a first-pitch, three-run homer in the sixth inning Friday night, and the Dodgers tightened up the NL wild card race with an 8-5 victory over the Cardinals.
"It was very uplifting," Dodgers left fielder Shane Victorino said. "In this game, confidence is very big. But to me, he's always been a great player, I played against him, and he's never gotten has his opportunity to really go out there and shine. Then it took Jerry getting hurt to get him his opportunity. And when he got it, he shined.
"He's one of those guys on this team that nobody talks about, but yet he's come up with big hit after big hit and played great defense. He's playing consistently at a high level, and I'm very happy for him," Victorino said.
Trevor Rosenthal (0-2) inherited a 4-3 lead from fellow rookie Joe Kelly after five innings and gave up a leadoff single by Andre Ethier, who got the Dodgers back into the game in the third with a two-run homer. Rosenthal hit Hanley Ramirez on a 1-0 count two outs later and manager Mike Matheny made the switch to Mujica -- who has given up 17 runs and six homers in 21 1/3 career innings against the Dodgers.
"I felt a little out of my timing today, so before that at-bat I just told myself to take a pitch, just to see if he was thinking about pitching me inside," Cruz said. "But I was relaxed, and I saw it just hanging there. So I just reacted and hit it. But I wasn't trying to hit a homer."
Mujica had allowed one run in 19 innings over his 20 previous appearances with St. Louis after he was acquired in a trade with Miami on July 31. The Dodgers had a similar come-from-behind victory over the Cardinals on May 20 at Dodger Stadium, when pinch hitter Scott Van Slyke hit a go-ahead three-run homer off Mark Rzepczynski in the seventh inning.
"It was one pitch," Matheny said. "We got him into trouble by putting a couple of guys on base, and that usually adds some tough outs. But he's been terrific for us. Joe was struggling, and it was one of those days for the bullpen to come in and pick up the starter in those middle innings. We all know very well that it's hurt us, and it continued to do so tonight."
"Tonight we scored some runs and played the game right," Cruz said. "It's our time now. And from now on we're going to keep playing hard every day. We've got to keep fighting. We're never going to give up, and I think we're going to come through and win a wild card spot."
Rookie Shawn Tolleson (2-1) pitched 1 1/3 innings of hitless relief for the victory after the Dodgers got starter Chris Capuano off the hook. Capuano was charged with four runs -- two earned -- and six hits in four innings, including second-inning solo homers by Yadier Molina and Matt Carpenter and a two-run shot in the third by Holliday.
The temperature was 96 degrees when Capuano threw his first pitch, and the 34-year-old left-hander grew even hotter under the collar in the second inning when Molina drove an 0-2 pitch to left-center for his 19th homer and Carpenter added his sixth of the season two batters later. It was the 12th time Capuano allowed two homers in an inning during his eight big league seasons.
The Dodgers, averaging only 1.6 runs over their previous eight games, got on the board in the bottom half when Gonzalez led off with a double and scored on a groundout by Cruz, but the Cardinals extended their lead to 4-1 in the third when Carlos Beltran reached on a two-out throwing error by shortstop Ramirez and Holliday cashed it in with his 27th home run.
The Dodgers responded in the bottom half when Ethier got the green light from manager Don Mattingly on a 3-0 pitch and drove his 18th homer deep into the pavilion seats in right-center after a two-out walk to Victorino -- back in the leadoff spot for the first time since Aug. 27 with second baseman Mark Ellis getting the night off.
"Dre's home run on a 3-0 green light was huge," Mattingly said. "He's dangerous and especially aggressive when you let him go on 3-0. This was a good time for those home runs. It's a two-game swing. I'm just glad I don't have to talk about another loss."
Second baseman Nick Punto, starting his third game with the Dodgers since he was acquired on Aug. 25 in the nine-player trade with Boston, slid head-first into first base each of his first two times up on slow bouncers to third baseman David Freese. He was out the first time and safe the second time, but was picked off by catcher Molina in the fifth with pinch-hitter Bobby Abreu batting and the Dodgers down 4-3.
Kelly allowed three runs and four hits in five innings with two strikeouts and two walks.
