"He's not in there because of the way things worked between Brayan and Tony the first time through," Reds manager Bryan Price said. "I think familiarity is important in this particular case. Our intentions are for Devin to get the bulk of the playing time. That's not going to change. He's just not starting today."
Mesoraco suffered a strained left oblique muscle near the end of Spring Training and had to start the season on the DL. He went on a three-game rehab assignment at Double-A Pensacola and went 0-for-5 with two walks and a sacrifice fly.
"It went good. There were no problems. I am 100 percent healthy and ready to go," Mesoraco said. "I think it was important to go down and play a couple of games just so that I know there are no problems in there and I won't have any worries when I'm up here. Everything went well."
To make room for Mesoraco on the 25-man roster, the Reds optioned rookie catcher Tucker Barnhart to Triple-A Louisville. Barnhart was 2-for-8 in three games, including two starts.
Mesoraco took no issue with not being in Monday's lineup.
"I can get my feet under me today and go from there," he said.
