A's place Dallas Braden on DL

OAKLAND, Calif. -- The Oakland Athletics have put lefty Dallas Braden on the 15-day disabled list and transferred right-hander pitcher Rich Harden to the 60-day disabled list.

Braden left Saturday's game after five innings with shoulder stiffness. He is 1-1 with a 3.00 ERA in three starts this season, a year after pitching a perfect game against the Tampa Bay Rays.

Harden has been out with a strained right shoulder since spring training. He was originally put on the 15-day DL retroactive to March 22.

The A's also announced Monday they acquired left-hander David Purcey from Toronto for minor league right-hander Danny Farquhar.

Farquhar was traded from Toronto to Oakland in November.
