PHOENIX -- The Dodgers added another name to the season-ending injury list by announcing that utility infielder Russell Mitchell will have arthroscopic surgery for torn cartilage in his left wrist Tuesday.

Mitchell, who spent most of the season at Triple-A Albuquerque, has played through the injury since May with the assistance of injections and was already scheduled for the debridement procedure once the season ended. But it became inflamed over the weekend and the decision was made not to wait.

The surgery will be performed by Phoenix hand specialist Dr. Don Sheridan and will require six to eight weeks for recovery, which should allow Mitchell to play at least part of the winter ball season in Venezuela, as he planned. He was expected to work on catching there to increase his value.

Mitchell joins Jonathan Broxton (elbow surgery), Casey Blake (neck surgery), Rubby De La Rosa (elbow surgery), Jon Garland (shoulder surgery), Andre Ethier (knee surgery), Vicente Padilla (neck surgery) and Juan Uribe (sports hernia surgery) with season-ending injuries.

In other medical news, Tony Gwynn, out since Sept. 15 with a bruised left shoulder, was available Monday night for pinch-hitting and defense, according to manager Don Mattingly.

Mattingly willing to help Kemp's chase

PHOENIX -- Dodgers manager Don Mattingly said he would consider batting Matt Kemp leadoff in Wednesday's season finale if the chance of an extra at-bat might matter in his quest for the hitting Triple Crown.

Kemp entered play Monday night leading the league in RBIs, tied for the home run lead with Albert Pujols and trailing Ryan Braun and Jose Reyes for the batting title.

"I might there," said Mattingly, who otherwise has resisted moving Kemp from the third spot he has occupied for most of the last two months.

Mattingly said he would likely field the lineup from Monday night throughout the series with the playoff-bound D-backs, as each game is expected to have an impact on home-field advantage in the postseason.
