SCOTTSDALE, Ariz. -- An injured oblique has sidelined Giants outfielder Andres Torres for a week and will prevent him from participating for Puerto Rico in the World Baseball Classic.

Manager Bruce Bochy added Thursday that left-hander Jose Mijares' playing status for Venezuela in the Classic is "doubtful" after reporting a tender throwing elbow, which the Giants officially called a posterior impingement.

The switch-hitting Torres' painful side has limited his ability to bat right-handed. An MRI confirmed Torres' ailment. He had appeared in two Cactus League games, most recently Tuesday against the Dodgers, and was 1-for-2 overall this spring.

Mijares allowed two runs and three hits while pitching the eighth inning in Wednesday's Cactus League game against the Angels. Mijares pitched a scoreless inning in his only other Cactus League appearance.

Torres had been expected to provide depth for Puerto Rico, while Mijares was projected for a bullpen role with Venezuela. Both players were due to leave Giants camp for their respective Classic teams this weekend.

Both are projected to make the Giants' Opening Day roster, but the club has an ample number of potential replacements if either player has to begin the season on the disabled list.

The Giants still have a sizable eight-man contingent bound for the 16-team international tournament: left-hander Jeremy Affeldt and right-hander Ryan Vogelsong (United States), third baseman Pablo Sandoval and second baseman Marco Scutaro (Venezuela), outfielder Angel Pagan (Puerto Rico), right-hander Santiago Casilla (Dominican Republic), right-hander Sergio Romo (Mexico) and Minor League catcher Tyler LaTorre (Italy).
