More from scout.com:
OaklandClubhouse.com has learned from a source that reliever Russ Springer has been traded by the Oakland A's. It isn't clear for who or to what team as of yet. Oakland is also placing left-handed starter Dallas Braden on the DL and recalling outfielder Aaron Cunningham and starter Clayton Mortensen. Mortensen will start tonight. The A's are also purchasing the contract of left-handed reliever Jay Marshall. We haven't confirmed what the third move will be on the A's roster yet.
Assistant GM David Forst said it's a straight waiver claim.
"We felt like it was a good opportunity to see some guys in Triple-A the last month of the season, and it gives Russ the chance to pitch in a pennant race," Forst said. "That's something he deserves at this point in his career. He's done a great job for us and he's been a great mentor for our youngsters."
There is still the potential that the team will place Dallas Braden on the DL tomorrrow if the infected rash on his left foot has not improved substantially.
