It was the second walk-off loss at Chase Field suffered by Troncoso in the past three weeks. He allowed a bases-loaded single in the 10th inning on Aug. 15, the same game in which Hiroki Kuroda took a line drive off his head.
It was an all or nothing at all game; the Dodgers scoring on a triple and two home runs and the Diamondbacks homering twice before receiving the gift run in the ninth that ended it.
The big lead the Dodgers built in April and May is a thing of the past and the final three games of the season, Colorado at Los Angeles, may decide the West Division title.
Neither team hit much in he clutch. The Dodgers were 1-for-5 with runners in scoring position and the Diamondbacks were 0-for-9 and left 11.
Rafael Furcal tripled into the right field corner off starter Dan Haren. Matt Kemp and Andre Ethier struck out before Manny Ramirez hard ground ball to third took a wild hop and nearly hit Mark Reynolds in the face.
He knocked it down but Furcal scored from third and Ramirez had an infield hit and an RBI.
Jon Garland started for the second time against his old team and gave up back-to-back home runs to Miguel Montero and Chris Young in the second inning.
Ramirez (#18) and Loney (#11) matched the back-to-back shots in the fourth to put Los Angeles back into a 3-2 lead but Arizona tied the game in the fifth.
Both teams had a shot at breaking the tie.
With one out in the top of the inning Matt Kemp and Andre Ethier singled but Manny Ramirez and James Loney struck out.
In the bottom of the inning Mark Reynolds was walked by Ron Belisario and George Sherrill took over, allowing a single. He wriggled out of the jam with a fielder's choice, a fly to short left and a ground ball.
Garland pitched well enough to win, allowing three runs over six innings. Haren gave up the same three runs and seven hits and, like Garland, came out of the game with a no-decision.
Ramirez finished with a pair of hits and two runs batted in. Six of the Dodgers hits came from Furcal, Kemp, Ethier, Ramirez and Loney. The final four slot in the oder went 1-for-15.
Torre had kind words for Troncoso. "The kid pitched well," he said. "He's an athlete who fields his position well. It's one of those things. When you hold Dan Haren to a tie and you're pleased."
Wolf, Lincecum Out
The Giants announced that their ace, Tim Lincecum was being held out of the Dodgers series because of a bask strain.
Then the Dodgers announced that their ace, Randy Wolf will miss the series with a stiff elbow.
"We didn't want the Giants to have anything on us," Torre joked. "Lincecum's out? We'll show you. Wolf's out. What do you think of that? Take that."
Lincecum's postponement sets up Brad Penny for a start in the Sunday game.
After a day off Thursday, Hiroki Kuroda moves up to get the start in the opener Friday. because of the injury to Wolf. Kuroda won his only start this year against the Giants, allowing one run over 6.1 innings at San Francisco on Aug. 10.
The Dodgers will face RHP Matt Cain (13-4, 2.51 ERA) who held Milwaukee to two runs on four hits in six innings in his last start.
