ANAHEIM -- Andrew Bailey spent more than four months rehabbing his troublesome right shoulder before making his long-awaited return to the Majors last Tuesday against the Nationals. He entered the game in the eighth inning to face Ryan Zimmerman, marking his first outing for the Angels since the first week of the season.
Bailey got ahead of Zimmerman, 0-2, but when he reached back for more on his third pitch of the night, he aggravated his shoulder once again.
"I felt a little slipping sensation in that shoulder joint and finished the inning pitching a little differently," Bailey said Tuesday. "To go through that rehab process, it's quite frustrating. Any injury is frustrating, but when you injure your shoulder and then you do the rehab and it's still not the same, you just don't know."
Bailey landed on the disabled list for the second time this season on Monday with a right shoulder strain, a setback that jeopardizes his chances of pitching again this season. Only five weeks remain in the 2017 campaign, and Bailey said he still needs to undergo more tests and meet with doctors before the Angels can determine a treatment plan for him.
"That's a decision that is not up to me," Bailey said. "I tried to pitch through it. For me, I'd be out there100 percent trying to grind, but the trainers and the doctors think right now [the shoulder is] at risk for major injury due to some of the instability and strain."
Bailey, who earned a one-year, $1 million deal after pitching well for the Angels last September, has thrown just four innings in the Majors this season. The 33-year-old reliever has a long history of shoulder issues, including reconstructive surgery in 2013.
"Anytime you can't be out there with the guys, it's frustrating," Bailey said. "For me personally, I can look at myself in the mirror and say I did things the right way this year to get back on the field. I'm just not physically able to get out there and bounce back and do the things I need to do. It doesn't make it any easier, but we'll get some answers and see what happens."
Ramirez hoping to return
Right-hander JC Ramirez, who was placed on the disabled list on Monday with an elbow strain, said he'll be shut down from throwing for at least a couple of weeks, but he remains hopeful that he'll be able to come back and pitch for the Angels down the stretch.
"I want to. I'm going to do everything possible to do it," Ramirez said. "I want to finish strong. I want to help the team in whatever way possible."
The Angels have not yet announced who will fill Ramirez's spot in the rotation on Thursday, but it will not be Jesse Chavez, who threw 43 pitches out of the bullpen on Monday night.

Worth noting
• The Angels promoted right-hander Jaime Barria from Double-A Mobile to Triple-A Salt Lake on Tuesday. Barria, 21, is ranked the club's No. 8 prospect by MLBPipleline.com and has logged a 2.83 ERA in 23 starts across two Minor League levels this season.
• The Angels honored vice president of communications Tim Mead by wearing socks featuring his photo during batting practice on Tuesday.
"Tim has worked very hard and has been a part of our organization for so long that we're happy he's immortalized in this small token," manager Mike Scioscia said. "We will wear these socks with respect and probably only wash them once or twice a year."
