Padres acquired LHP Marc Rzepczynski from the Indians in exchange for OF Abraham Almonte.
Rzepczynski holds a 4.43 ERA over 45 relief appearances this season. There's a good chance the Indians would have non-tendered him over the winter.
Cardinals optioned RHP Miguel Socolovich to Triple-A Memphis.
He's making room for Jonathan Broxton on the roster. Socolovich is being sent out even though he holds a 1.54 ERA over 21 relief appearances.
Tigers recalled OF Tyler Collins from Triple-A Toledo.
He's taking Yoenis Cespedes' spot on the roster. Collins hit .275/.315/.490 with two homers and seven RBI in his 51 at-bats with the big league club.
Orioles recalled RHP Mike Wright from Triple-A Norfolk.
He's taking Tommy Hunter's spot on the roster and will pitch out of the bullpen. Wright holds a 5.16 ERA over 29 2/3 innings for the big club this season.
Cubs designated RHP Ben Rowen for assignment.
The move clears a spot on the 40-man roster for Dan Haren. Rowen was only up with the Cubs for a couple days and didn't make an appearance.
