PHOENIX -- Only 242 games into his Major League career, every day is a learning experience for Matt Kemp.

After ending Saturday's game with a weak fly to right with the tying run at third against D-backs closer Brandon Lyon, Kemp was put in an eerily similar situation on Sunday against Lyon, the only difference being the runner was at first.

This time Kemp came through, fouling off four pitches during an eight-pitch at-bat before lacing a tying double to left-center to lead the Dodgers to a 6-5 victory. On Saturday he swung at the first pitch to end the game.

"He just seemed very calm," Dodgers manager Joe Torre said. "You try to learn something from yesterday, especially in the situation you come in. Here it is, game in the balance again and has the kind of at-bat he had, so I just think it's been a progression."

Added catcher Russell Martin, "When you start seeing so many pitches you start getting comfortable, especially when you get a feeling he doesn't have anything to beat you with. Then he finally got something to handle and he just squared it up nicely."

Kemp called the at-bat his best of the year, entering with the mind-set of not trying to do too much, as big hacks have led him to team-high 106 strikeouts. Torre said Kemp also appeared to come to the plate with a better plan against Lyon than he had on Saturday.

"His ball runs in a lot," Kemp said. "Basically if it starts middle probably lay off it because it might run in on my hands, but he threw me a straight fastball inside, and I turned on it and got a double out of it and we scored a run to tie the game up."

Kemp delivered the big blow, but the ninth-inning comeback was a team effort in which six players recorded hits and five batters drove in runs.

Nomar Garciaparra started the rally off by jumping on a fastball for a double, and James Loney followed with a single on the first pitch to bring the tying run to the plate.

Los Angeles dodged a bullet when Stephen Drew bobbled Andruw Jones' ball up the middle, leading him to get only get one out instead of a rally-harming double play. If the D-backs had completed that play, Blake DeWitt's subsequent groundout would have ended the game, instead of leaving the door open a crack.

Andy LaRoche followed with a pinch-hit RBI single in which he also learned from his at-bat Friday against Lyon when he just missed a first-pitch hanging curveball, hitting it out to center for an out.

This time LaRoche correctly predicted Lyon would start him out with an outside fastball, which LaRoche jumped on for his single.

"I was just going to try to drive it to right field," said LaRoche, who did just that. "It was a little further out than I was expecting, but I was able to get decent wood on it and let it sit out there without them catching it."

Newly acquired Pablo Ozuna ran for LaRoche, setting up Kemp's dramatics, but the rally did not end there.

Andre Ethier promptly waited for a fastball he could drive for a go-ahead triple three pitches later.

"I've got to jump on board with what everyone else was doing that inning and join along in it," Ethier said he was thinking. "It wasn't as much pressure as [Kemp]. He had the big hit tying the game up. For me it was just a go-ahead run, so I got in a hitter's count and was able to take a chance and was able to put a swing on a pitch. It was kind of contagious."

After D-backs fans booed Lyon off the mound, Martin capped the onslaught with a run-scoring single against Leo Rosales.

The comeback stunned Arizona fans who had watched D-backs starter Brandon Webb carve up the Dodgers in allowing just one run in eight innings before the comeback.

"It took us nine innings to get a big inning, but we got those runs that we needed to win the game," Kemp said. "Today was a new day. It came out good for all of us."
