Casey Fien was back in the Twins bullpen Friday, his shoulder healed and his fears allayed.
"When you get that [magnetic resonance imaging test], you never know what it's going to show, so that's what scared me the most," the 31-year-old righthander said. "But when the MRI came back and showed a healthy shoulder, we knew it was muscle, and it would just take some time to throw pain-free."
It took about three weeks, plus another spent on a rehab assignment with Class AAA Rochester. Fien was activated Friday, though he understands his setup role in front of closer Glen Perkins belongs to Blaine Boyer, at least for the moment.
"I would imagine at least in the short term, if we get in a situation late … Casey would probably precede Boyer into the game," more likely the seventh inning than the eighth, manager Paul Molitor said. "That could change; we'll see how Casey's doing. But for now, I'm comfortable with Boyer out there, getting outs in the eighth inning."
That's OK with him, Fien said.
"Roles don't really matter. It's about getting outs," he said. "And sometimes those outs in the seventh inning are the biggest ones in the game. So I'll be ready."
Tonkin optioned down to Rochester
To make room for Fien, the Twins optioned righthander Michael Tonkin to Rochester, though Molitor emphasized that "it's not a matter of him doing anything wrong. It's just a matter of how it fits right now."
Tonkin pitched in 11 games and posted a 5.14 ERA since being called up to replace Fien four weeks ago, but he had held the opposition scoreless in five of his past six outings. He struck out seven and walked two in his seven total innings and allowed only three of 13 inherited runners to score.
