ANAHEIM -- The Angels placed right-hander Andrew Bailey on the 10-day disabled list on Wednesday, retroactive to Monday, with right shoulder inflammation.
Bailey last pitched against the Mariners on Sunday and had posted three scoreless innings over his first three outings of 2017, but he began feeling discomfort in his shoulder on Monday.
"His shoulder acted up a little bit, so we're just going to take a little step back," manager Mike Scioscia said. "We want to be very conservative with Andrew. He threw the ball so well coming back at the end of last year. We want to get him back there, so we're going to let him settle in and hopefully get his shoulder where it needs to be."
Bailey logged a 2.38 ERA over 11 1/3 innings and saved six games for the Angels last summer after joining the club on a Minor League deal. The 32-year-old veteran won the '09 American League Rookie of the Year Award with the A's and was later traded to the Red Sox, though he struggled to stay healthy in Boston and missed the entire '14 season after undergoing surgery to repair a torn labrum and a torn capsule in his throwing shoulder.
Scioscia said Bailey does not believe his latest shoulder flare-up is as serious as what he faced with the Red Sox, but the Angels manager added that it's too early to say if Bailey will be sidelined for more than 10 days.
"Andrew doesn't feel this is the same scope that he had like back in Boston where it really was bothering him," Scioscia said. "But naturally, we're concerned enough to shut him down. Hopefully it won't be too long, but we want to take that first step."
Bailey opened the '16 season with the Phillies, but he was released after posting a 6.40 ERA over 32 1/3 innings. He ultimately landed with the Angels, who were in need of bullpen depth following the injuries to Huston Street and Cam Bedrosian. Bailey pitched well enough in September to earn a one-year, $1 million contract from the Halos over the winter.
With Bailey and Street on the disabled list, the Angels are now without two of their most established backend options in the bullpen, though the rest of their relief corps had performed well entering Wednesday, posting a combined 2.45 ERA.
The Angels recalled right-hander Daniel Wright from Triple-A Salt Lake on Wednesday to take Bailey's spot on the roster. Wright, 26, was claimed off waivers from the Reds last year and went 1-3 with a 5.40 ERA over five starts for the Halos in September.
"He picked up a better slider, which I think is something that can definitely help him," Scioscia said. "He spins it really well. He's got a real good curveball, he's got a nice changeup and he hits his spots with his fastball. Although he's not overpowering, his stuff plays up because of the way he spins the ball."

Worth noting
• Right-hander Garrett Richards (right biceps strain) had said that he hoped to resume throwing on Tuesday, but Scioscia said he still has not been cleared to do so by the team's medical staff.
"He's not throwing, but he's moving in the right direction," Scioscia said. "We'll just see when those guys feel he's ready to throw."
Scioscia said the Angels still have not decided who will take Richards' spot on the rotation on Saturday when they face the Royals in Kansas City, though Wright, Yusmeiro Petit, JC Ramirez and Alex Meyer are likely among the candidates.
