"He needs to play -- it's not fair to him to sit," Twins manager Ron Gardenhire said. "He needs to get at-bats right now. He's had issues throwing and issues catching the ball lately. I think it's probably due to not getting enough reps back there. I think this is the right thing to do. He needs to work on some things mechanically behind the plate with his throwing and his catching and framing the ball."
Pinto has had trouble defensively this year, as he's yet to throw out an opposing basestealer in 16 attempts and has made five errors. He's also still working on his pitch-calling and framing skills.
Triple-A catchers Eric Fryer and Chris Herrmann are both on the 40-man roster, and one of the two is expected to be called up to replace Pinto. Fryer is the frontrunner to be recalled, as Herrmann has been dealing with a wrist issue.
Pinto, 25, started off hot offensively but cooled down since May 1. Some of his scuffles could come from a lack of consistent playing time, but he hit just .200/.227/.329 with two homers and seven RBIs in 23 games since May 1.
"This is going to help him," Gardenhire said. "This kid has a chance to be a starting catcher and not a backup with his offense. So it's the right thing for him to just go catch."
