MINNEAPOLIS -- Right-hander Samuel Deduno had his right shoulder examined by team doctors after his start against the White Sox on Sunday, according to Twins assistant general manager Rob Antony.
Deduno struggled for a third straight start, giving up five runs on eight hits over five innings while hitting three batters. He complained of shoulder soreness after the game, but he checked out OK and remains tentatively penciled in to make his next start on Friday against the Indians.
"The doctors are just going to keep an eye on him," Antony said. "We're not going to rule him out for his start on Friday. But that's subject to change. We'll keep an eye on him and see how he is this week."
Deduno had a 3.17 ERA through his first 13 starts this season, but has a 7.02 ERA over his last three starts to see his ERA for the season rise to 3.82. Twins manager Ron Gardenhire said he's noticed a difference in the effectiveness of Deduno's curveball in recent starts.
"It's getting to a certain point and just hanging there right now," Gardenhire said. "And when his arm speed is good, it's snapping pretty good."
