Mark Trumbo done for season

ANAHEIM, Calif. -- The Los Angeles Angels learned Monday that they would be without their leading power hitter for the final three games of the season against the Texas Rangers.

Doctors discovered a stress fracture in the right foot of first baseman Mark Trumbo, according to the rookie slugger. Trumbo leads the team in home runs (29) and RBIs (87) and has a chance to be the Angels' first Rookie of the Year since Tim Salmon in 1993.

"Of course I'm disappointed, but I've been playing with this pain for a month-and-a-half," Trumbo said. "If I keep playing, I could hurt the team right now."

Trumbo, 25, inherited the Angels' first-base job when Kendrys Morales struggled to return from a broken left ankle he fractured in May of 2010. Morales announced he was having season-ending follow-up surgery this past May. Trumbo is batting .254 and leads all major league rookies in home runs and RBIs.

Trumbo's injury is expected to keep him out of baseball activities for at least six weeks and could mean he'll have to cancel plans to play winter ball in Venezuela. The Angels were hoping Trumbo could work on playing third base and the outfield in winter ball, with an eye on accommodating both Morales and Trumbo in their lineup next season.

Morales, 28, finished fifth in MVP balloting in 2009, when he batted .306 and had 34 home runs and 108 RBIs.

Trumbo had to leave the Angels' past two games against the Oakland Athletics because of pain in his foot. Since hitting his 29th home run on Sept. 20, he was 3-for-20 (.150) with six strikeouts. The stress fracture is in Trumbo's navicular bone, a small bone at the top of the foot.

Morales was in the Angels' clubhouse before Monday's game and walking without a noticeable limp or a walking boot. The Angels are hoping he'll be cleared for full baseball activities by the start of spring training, but they had similar hopes last February.
