Liriano was sent to Triple-A Rochester before Friday night's game at Texas, and it was not a surprise. He gave up six runs and got only two outs on Thursday against Oakland, his latest failure to find the strike zone in a return from reconstructive elbow surgery.
"He knew he needed to improve. It wasn't a shocker to him," manager Ron Gardenhire said. "He saw where he was at and he knows he's got work to do. Maybe he can clear his head, get after it down there and get back up here."
Right-hander Bobby Korecky was recalled from Rochester to take Liriano's roster spot. Korecky was the closer for Rochester, going 2-1 with an 0.68 ERA and five saves in 13 1/3 innings.
