The Dodgers won, 5-2 Tuesday, but were eliminated from playoff contention by Arizona's 10-1 victory over Colorado.

Rickey Henderson got on base twice but failed to score, remaining one run short of matching Ty Cobb's all-time runs record.

And Tony Gwynn's right knee was too sore to allow him to pinch hit as he began his final homestand. Gwynn will play the final game of his 20-year big league career on Sunday against Colorado. He has torn cartilage in his right knee and will have surgery next week.

Paul Lo Duca homered twice for the Dodgers, including a go-ahead solo shot leading off the ninth inning, and threw out Henderson trying to steal second base in the eighth inning.

The Dodgers had lost 11 of their previous 15 games, and sensed elimination was just a matter of time.

"We have only ourselves to blame," Lo Duca said. "We had many chances and a lot of shots to get in this race and we didn't take advantage of them. At one time we were leading the wild card and we were leading the NL West at one time."

It was the second multihomer game for Lo Duca, who's connected 24 times this season. His ninth-inning homer to left field came on a 2-2 fastball from Trevor Hoffman (3-4) to break a 2-2 tie. Dave Hansen added a sacrifice fly and Tom Goodwin a two-out RBI infield single to chase Hoffman.

Lo Duca had just five big-league homers coming into this season.

"I never thought I'd hit this many home runs, I'll tell you that," he said. "I'm still having fun out there. We still have five games left in the season. They count, so we've got to play."

Giovanni Carrara (5-1) pitched two scoreless innings with three strikeouts for the victory. Jeff Shaw pitched the ninth inning for his 41st save in 50 opportunities, tying him with Todd Worrell for first place on the Dodger's career save list with 127.

Henderson went 0-for-2 with no runs scored to remain one run shy of tying Cobb's record of 2,245 runs, and three hits from becoming the 25th player with 3,000.

Henderson walked twice, but was erased both times. He reached leading off the sixth and was forced on D'Angelo Jimenez's double-play ball. One batter later, Ryan Klesko hit a 424-foot homer into the right-field seats to tie the game at 2.

Henderson walked with one out in the eighth and was thrown out by Lo Duca, the Dodgers' catcher, trying to steal second. TV replays showed Henderson was safe on a close play.

"He stole a big base on us in LA and I knew he was going to go one of those pitches," Lo Duca said. "We got lucky, I got a good pitch I could handle that was out of the strike zone away, and I made a good throw and he was barely out."

Henderson hasn't scored in four consecutive games. He sat out the final two of a four-game series at Colorado after moving within two runs of breaking the record.

"He got on base twice, but as a club we didn't swing the bat well," manager Bruce Bochy said.

Klesko's homer off starter Terry Mulholland was his career-high 150th hit of the season. His previous best was 149 in 1996 while with Atlanta.

The Dodgers took a 2-1 lead on Eric Karros' RBI double with two outs in the sixth, scoring Gary Sheffield from first. Henderson got turned around on Karros' fly ball, which bounced off the left-field fence.

San Diego's Ben Davis hit a solo homer to left-center with two outs in the second, his 11th. Lo Duca connected with one out in the fourth to tie it at 1 in the fourth.

Mulholland allowed two runs and five hits in six innings, struck out one and walked three. San Diego's Brian Lawrence went seven innings, allowing two runs on seven hits, striking out seven and walking two.
