ANAHEIM -- The Angels' rotation took another hit Tuesday, as Matthew Shoemaker was placed on the 10-day disabled list with a right forearm strain. Parker Bridwell was recalled from Triple-A Salt Lake to take Shoemaker's place on the roster.
Shoemaker said Wednesday he underwent an MRI, but the results aren't known yet.
Shoemaker is the second Angels starter to land on the disabled list less than a week into the regular season, joining left-hander Andrew Heaney, who is on the mend from elbow inflammation.
Shoemaker, 31, said the issue first arose near the end of his season debut Saturday, when he earned the win after allowing three runs over 5 2/3 innings against the A's.
"I started feeling a little bit of achiness, but nothing that was even a red flag," Shoemaker said. "Less than mild. I wasn't even concerned with it. Later that night and the next day, I just kind of felt worse than previously."

Shoemaker also dealt with a forearm issue last year, which required season-ending surgery to release the radial nerve in his right arm. He said the symptoms are similar, though he added that the Angels still need to put him through multiple tests before determining a diagnosis.
"We decompressed the nerve previously, and that's the fix," Shoemaker said. "Being completely honest, that did fix it from then until essentially now. We don't even know if that's what it is now. The symptoms are a similar feeling. Where they decompressed that tunnel, that's completely clear, so maybe scar tissue from the procedure is in the area. We have to do all this stuff to figure out what it is."
Bridwell will slot into Shoemaker's rotation spot and is scheduled to make his season debut Friday in the Angels' series opener against the A's at Angel Stadium. The 26-year-old right-hander was a revelation for the Angels in 2017, going 10-3 and logging a 3.64 ERA over 121 innings.

Despite his success last year, Bridwell didn't make the Angels' Opening Day roster, as the club recovered most of its rotation depth after Garrett Richards, Tyler Skaggs, JC Ramirez, Heaney and Shoemaker reported to Spring Training healthy after missing large chunks of last season due to injury.
Aside from Shohei Ohtani, the Angels made no notable additions to their rotation over the offseason, as they were counting on improvements to come from a healthier staff. Only five games into the 2018 campaign, that plan is already being tested.
"We've peeled the paint off everything you can possibly do from the medical side to the training to seeing how these guys' strength is and their recovery," manager Mike Scioscia said. "Sometimes these things still crop up. You never have a team that goes through less than six to nine or 10 starters throughout a season at some point. Hopefully we'll get guys throwing the ball the way they can and keep them healthy. That's what we anticipate."
Worth noting
The Angels announced the rest of their rotation order for their upcoming series against the A's. Ramirez will follow Bridwell on Saturday, while Ohtani will make his first start on the mound at Angel Stadium in Sunday's series finale.
Ohtani, who was in Tuesday's lineup as the designated hitter against the Indians, notched his first career win against Oakland after allowing three runs over six innings on Sunday. The 23-year-old two-way phenom will again pitch on six days' rest.
