LOS ANGELES – A key member of the Mets’ bullpen is lost for at least the next two weeks.

Brooks Raley was placed on the 15-day injured list Sunday with left elbow inflammation, depriving the Mets of their primary left-handed weapon from the bullpen.

In eight appearances this season, Raley has not allowed an earned run, with nine strikeouts and three walks in seven innings.

He last pitched on Friday, when he pitched two-thirds of an inning scoreless against the Dodgers.

Raley’s injury leaves Jake Diekman as the lone left-handed option in the bullpen.

The Mets recalled right-hander Grant Hartwig from Triple-A Syracuse to take Raley’s roster spot.
