Butera served as Liriano's personal catcher over Liriano's last 11 starts with Minnesota, but now isn't tied to any of the club's five starters.
But Gardenhire said he's looking to give Joe Mauer a rest at some point on the club's seven-game road trip to Boston and Cleveland to give Butera a chance to start.
"I don't have to line him up with anybody," Gardenhire said. "We'll get him in a game pretty quick. He needs to catch. It'll give me a chance to mix Drew in. I know fans like to see Joe Mauer play every day, but there will be a time on this road trip where I'm going to give Joe a day off."
