MRI reveals tear in left quad for Nomar

First baseman likely limited to pinch-hitting duties for NLDS

LOS ANGELES -- Dodgers first baseman Nomar Garciaparra will likely be limited to a pinch-hitting role for the remainder of the National League Division Series against the Mets.

During his Friday afternoon press conference at Dodger Stadium, Dodgers manager Grady Little revealed that an MRI has shown Garciaparra to have a tear in his left quadriceps muscle.

"He'll be very limited for the rest of this series," Little said. "Pinch-hitting is a possibility. Running is the hard part."

Garciaparra originally tweaked his left quad during a Sept. 15 game against the Padres. He aggravated the injury while legging out an infield single in the fourth inning of Thursday night's 4-1 loss at Shea Stadium.

Over the previous few weeks, Garciaparra had managed to avoid aggravating the injury. But as he was running down the first-base line on Thursday night, he pushed himself a little harder and felt immediate discomfort.

Garciaparra didn't exit the game until he grounded out to begin the sixth inning.

Rookie first baseman James Loney will likely replace Garciaparra in the Dodgers' lineup. During the final two months of this year's regular season, the left-handed-hitting Loney hit .333 (18-for-54) with three homers and 39 RBIs.
