Bauer joined the Cleveland Indians as part of a 9 player 3 team trade, which saw the Indians ship out Shin-Soo Choo and Jason Donald to the Reds, and Tony Sipp and Lars Anderson to the Diamondbacks, while receiving Bauer along with Drew Stubbs, Matt Albers, and Bryan Shaw from the Reds and Diamondbacks. Trevor was 21 at the time of the deal, a pitcher out of UCLA, and was the 3rd overall pick in the 2011 Amateur Draft by the Arizona Diamondbacks.
