LOS ANGELES (AP) -- The Los Angeles Dodgers no sooner got Zack Greinke back from the disabled list when Josh Beckett took his place there.
Beckett went on the 15-day DL on Wednesday with a strained left groin. He is 0-5 with a 5.19 ERA in eight starts this season.
He left after three innings of Monday's 6-2 loss to Washington when he tweaked his groin covering first base on a grounder.
Manager Don Mattingly indicated after the game that Beckett "had some stuff going on" unrelated to the groin strain, but he offered no specifics.
Greinke was reinstated in time to start the series finale on Wednesday night. He had been out since breaking his left clavicle in a fight with San Diego's Carlos Quentin on April 11.
