"He's been throwing the entire time," Ryan said before Saturday's 15-4 loss to the Red Sox. "He's been throwing and he's been throwing often. We thought we were close and it didn't go well. We're going to let him rehab without throwing and then ramp him back up."
Ranked by MLBPipeline.com as the Twins' No. 11 prospect, Meyer boasts a 1.04 ERA over 17 1/3 innings for the Red Wings with 19 strikeouts, but he owns a 12.27 ERA in 3 2/3 innings with Minnesota this season.
"The good news is there's no structural problem,"Ryan said, "but we're losing the summer. He's going to rest, then we'll have the ability to get him going again."
