New Twins reliever Sam Dyson's shoulder problems trace back to a July 15-17 series at Colorado during which he started to experience discomfort and tried to pitch through it.
Dyson pitched twice in the series for the Giants — the second game of a doubleheader on the 15th and on the 17th.
"My shoulder started bugging me, and I just kept throwing through it and throwing through it," he said.
Dyson then made five scoreless appearances after that before being dealt to the Twins on Wednesday for three minor leaguers. He was pitching well and apparently didn't tell the Giants about his condition — even though he said he felt discomfort when doing minor tasks like picking up a plate in the kitchen or changing clothes.
"It's something pitchers always have," he said. "I think everyone is always working through something. It's been there. Just been grinding on it."
But after two poor outings as a Twin — he gave up six earned runs in two-thirds of an inning — Dyson called General Manager Thad Levine to inform him of what he's been dealing with. The Twins then decided that placing him on the injured list was the best course of action.
Dyson has been resting ever since. He expects to start doing shoulder exercises Wednesday or Thursday. Then he'll play catch by the weekend and hopes to throw in the bullpen by early next week.
"I was just grinding through it the whole time, and I didn't want to put these guys in a bad spot because they're in first place," Dyson said.
