Deduno walked Eric Chavez with two outs before being met at the mound by Twins manager Ron Gardenhire and trainer Dave Pruemer. The decision was then made to remove Deduno from the game after just 30 pitches.
Deduno, who had his eye checked out earlier in the week, claimed he was fine, but Gardenhire said it was obvious that he wasn't.
"They kept throwing the ball back to him from the catcher and first base, and he kept dodging it, so we went out there to check him out," Gardenhire said. "He's had his eyes checked over the last few days, and everything was fine and he says he was fine, but that's not fine. There's no way we're gonna leave him on the baseball field with that."
Left-hander Brian Duensing came in to replace Deduno, and struck out Raul Ibanez to end the inning. But Duensing ended up giving up six runs in the third inning, as the Twins ended up losing, 8-2.
Deduno tossed 1 2/3 scoreless innings with two walks, two strikeouts and no hits allowed. Of his 30 pitches, 15 were balls.
Gardenhire also wouldn't rule out that Deduno will make another start this season, as he could start next week in Toronto in the club's final series of the year if all goes well. He's scheduled to get his eye re-examined on Thursday.
"If you talk to him, he says he's fine, but we want to get him checked out before he goes back out there," Gardenhire said. "We have to know for sure before we put him back out there. So I'm not saying he's done. We just need to check him out and see if there's anything they can do to help him out."
