PITTSBURGH -- Dodgers skipper Don Mattingly said the team's other primary third baseman this season, Juan Uribe, "took a little step back" in his rehabilitation from an injury that has had him on the disabled list for the past six weeks.

Mattingly said Uribe's ailment has been re-characterized as a sports hernia (he's officially listed as out due to a left hip strain), and that surgery to correct it is now an option after it did not respond well when it was pushed this week. Mattingly said "it doesn't look like" Uribe will return this season.

"The agent and the player at this point need to make a decision and make sure they're doing their due diligence on exactly what they want to do and what's the best thing from here," Mattingly said when asked if surgery was likely.

Blake to have season-ending surgery

PITTSBURGH -- Casey Blake had the rare opportunity to know exactly when his last game of the season would be due to injury.

Blake, the Dodgers' third baseman when healthy, has been bothered by a pinched nerve in his neck all season. The pain didn't completely go away through three disabled-list stints, but Blake kept on playing.

Until now. The veteran did not make the trip with the team to Pittsburgh for the makeup game Thursday, and he will undergo surgery next week, ending his season.

"The whole idea is that this will give him the best chance to give it a run (at Spring Training next year)," Dodgers manager Don Mattingly said. "He told me [Wednesday] -- we all knew it was his last day -- that he felt like a dog that was going to the vet. You put him in a car and he's kind of like, 'Hey I'm going to the vet. I'm in the car.' And then you get to the vet and you get sleepy, get tired. So I thought that was a good analogy."

Mattingly said it was important to Blake for him to make it to Sept. 1 so that he wouldn't be harming the team as much, what with the expansion of the active rosters.

Mattingly described the procedure as "giving the nerve some space" and that Blake, 38, wishes to continue playing.

"Hopefully this gives him the best chance to do that," Mattingly said. "I don't know the exact time before he really get back to baseball [workouts/activities], but it gives him that extra month of time to kind of get into the winter and have this process already started."

Dodgers add three to roster, more moves expected

PITTSBURGH -- The Dodgers made a few expected roster moves official on Thursday. The club purchased the contract of left-hander Dana Eveland from Triple-A Albuquerque to start against the Pirates Thursday. Shortstop Dee Gordon was activated from the disabled list and was in the lineup leading off. Also, infielder Russell Mitchell was recalled from Albuquerque.

Mattingly said the team will give Gordon plenty of playing time the final four weeks of the season to Gordon. The 23-year-old speedster was out with a bruised right shoulder.

"We're going to continue to see what he can do," Mattingly said.

Mitchell will play some at third base because of the hole created by injuries at that position, but he also will see time around the diamond. Long-term, the Dodgers view him as a potential "super-utility" player.

Throughout his Minor League career, Mitchell has played every position but centerfield and catcher -- and Mattingly said the Dodgers are considering giving him some work there in winter ball.

"We look at him as a guy who can play a lot of places," Mattingly said.

The Dodgers will not call up any other players until their Minor League seasons are over. Albuquerque's season will end Monday. Mattingly said "at least another five or six" players will be added to the active roster.
