NEW YORK (AP) The Oakland Athletics have signed free agent slugger Chris Carter to a minor league deal and promoted right-hander Frankie Montas and first baseman/outfielder Matt Olson to the majors.
The A's made the moves before playing the New York Mets on Friday night.
Carter was recently cut by the New York Yankees after hitting .201 with eight home runs and 26 RBIs. He tied for the NL lead with 41 homers for Milwaukee last year but struggled as a first baseman and designated hitter for the Yankees.
Carter was assigned to Triple-A Nashville. He played for Oakland in 2010-12 and hit 19 home runs.
Montas was 1-1 with a 6.91 ERA in 21 relief appearances for Oakland before being sent down on June 11.
Olson is joining Oakland for the fifth time this season. He hit .184 with four homers and nine RBIs in his previous four stints.
