Twins recalled DH Kennys Vargas from Triple-A Rochester.
There was some optimism about Vargas coming into the year, but he has batted just .245/.277/.365 over 166 plate appearances with the Twins this season. He'll provide some pop off the bench.
Twins purchased the contract of C Eric Fryer from Triple-A Rochester.
Fryer was removed from the 40-man roster a month ago, but he's back to serve as a third catcher down the stretch. The 29-year-old is 3-for-18 (.167) with 11 strikeouts with the Twins this season.
Reds recalled RHP Carlos Contreras from Triple-A Louisville.
Contreras was thumped to the tune of nine runs on 11 hits over 13 1/3 innings while pitching in the Reds pen earlier this season. He could see some relief duty now that he's back on the roster, but there's no reason to expect big numbers from the 24-year-old right-hander.
Twins sent LHP Jason Wheeler outright to Triple-A Rochester.
The move clears a spot for Eric Fryer on the 40-man roster. Wheeler, 24, has posted an ugly 6.58 ERA over 15 starts at the Triple-A level this season.
Reds purchased the contract of C Ramon Cabrera from Triple-A Louisville.
Cabrera was hitting .290/.243/.353 with two homers and 35 RBI in 317 at-bats for Triple-A Louisville. The 25-year-old catcher doesn't have much much of a bat and does not present a fantasy option.
