League slightly behind bullpen colleagues

GLENDALE, Ariz. -- Most of the relievers expected to be in the Dodgers' bullpen this year threw live batting practice on Wednesday, while Brandon League returned from a mild lat strain to throw a bullpen session.

Among those throwing to hitters were closer Kenley Jansen, Brian Wilson, Chris Perez and J.P. Howell. League said he threw cautiously with no discomfort and hoped to do so again on Friday before facing hitters.

Meanwhile, reliever Jose Dominguez tried out a new slider grip suggested by legendary lefty Sandy Koufax and reported improved downward break on the pitch.

Manager Don Mattingly said Zach Lee, who has been on a restricted throwing program because of a strained lat, might return to the mound on Thursday.

And reliever Yimi Garcia has a bruised kneecap and has resumed playing catch.
