Treanor injures side in pregame batting practice
LOS ANGELES -- Dodgers backup catcher Matt Treanor apparently suffered a strained left side muscle while taking batting practice before Tuesday night's game with the Giants and left the field in pain.

The 36-year-old Treanor, who has played only 36 games while backing up A.J. Ellis, was attended to by manager Don Mattingly and left the field with assistant trainer Greg Harrel.

Because rosters have expanded, the Dodgers have rookie Tim Federowicz on the active roster to back up Ellis.
