He said the soreness in his shoulder began in a bullpen session after his start against the Mariners on May 17, and that it progressively got worse. But he was relieved that an MRI showed inflammation in the back of his shoulder, and he plans on throwing a bullpen on Saturday in Kansas City.
"It's not that sore and feels better," Liriano said. "It's getting there, I think. It's still there a little bit. But it feels better than before. I don't want to keep fighting this all year."
Right-hander Anthony Slama was recalled in his place and was excited to rejoin the Twins' bullpen after making five appearances with the club last season.
"I was so happy when my manager in Triple-A told me yesterday," said Slama, who has a career 2.73 ERA and 117 strikeouts in 105 innings at Triple-A Rochester. "I'm ecstatic. This is where I want to be."
Slama made his season debut on Tuesday, tossing 1 1/3 scoreless innings in relief of left-hander Brian Duensing in an 8-7 loss.
