Guerra joins Team Mexico for Classic

GLENDALE, Ariz. -- Dodgers reliever Javy Guerra said he will be a late addition to Team Mexico's entry in the World Baseball Classic after Cleveland closer Chris Perez left the roster for Team USA due to injury. D-backs reliever David Hernandez then switched from Team Mexico to the United States' squad, after being ruled ineligible for Mexico.

Guerra came to camp as the Dodgers closer last spring but is now fighting for a job after an injury-plagued season, and said he met with general manager Ned Colletti Saturday.

"Ned said it was my personal choice," said Guerra. "I'll be facing the world's elite. When I come back, at that point I'll compete for a job and go out and prove I can pitch."

Clubs are supporting player participation in the Classic, even though from a preparation standpoint players like Guerra will miss a portion of camp while other job candidates will be more closely observed.

"I'm not going to penalize Javy for playing for his country," manager Don Mattingly said late Saturday. "As a manager, you want all of your players in camp. But for the good of the game internationally, I think we have to sacrifice our guys. They are playing baseball; it's not like they're playing basketball someplace."

Guerra will pitch one inning for the Dodgers in Sunday's game against Cleveland, then join Team Mexico, which will train at Camelback Ranch. It will be only his second game appearance since shoulder surgery.

Guerra is the third Dodger on Team Mexico (joining Adrian Gonzalez and Luis Cruz). Hanley Ramirez will play for Team Dominican Republic, Ronald Belisario for Team Venezuela and Nick Punto for Team Italy. Ramirez and Belisario leave the club Sunday, the others on Monday.
