CINCINNATI (AP) — The Reds put left-hander Tony Cingrani on the 15-day disabled list because of soreness in his pitching shoulder, giving them two starters sidelined by injury.

They called up right-handed reliever Curtis Partch on Thursday for the start of a four-game series against the Milwaukee Brewers. Manager Bryan Price says the Reds won’t need to add another starter because they have three days off in the next two weeks.

The Reds opened the season with eight players on the disabled list, the most in the majors. Right-handed starter Mat Latos had surgery to repair torn knee cartilage on Feb. 14 and later developed soreness in his pitching forearm. There’s no expectation for when Latos will be back.

Price said Cingrani should be ready to return in two weeks. The move on Thursday was more of a precaution.

“He’s felt like it hasn’t impaired his pitching, but he’s aware he hasn’t felt 100 percent like his first game against the Cardinals,” Price said. “I think he can still pitch with it. All things considered, we don’t want 60 percent to 70 percent of Tony Cingrani if we can get closer to 100 percent. And we’re going to take advantage of this spot in the schedule to get him right.”

Cingrani is 2-2 with a 3.34 ERA in six starts. He gave up three runs in four innings of a 9-4 loss to the Cubs on Wednesday night, with his velocity dropping in the final inning.

Cingrani would have liked to stay in the game longer on Wednesday and remain in the rotation, pitching through the problem.

“I don’t know why they do a lot of things,” Cingrani said. “I don’t agree with it, but that’s what they want to do because they don’t want me to injure myself, so I understand. I think I could throw just fine, but they’re exercising caution.”

Partch opened the season with the Reds and didn’t allow a run in 4 1-3 innings. He retired 13 of the 17 batters he faced. He was optioned to Triple-A Louisville on April 19 when left-handed reliever Sean Marshall was activated.
