BALTIMORE -- The Orioles placed their 12th player on the injured list on Sunday afternoon, before adding a 13th on Monday.
Prior to Baltimore's 6-2 win over San Francisco in the series finale at Camden Yards, outfielder Tyler O'Neill was placed on the 7-day concussion IL, retroactive to Thursday. The 30-year-old missed the first two games against the Giants as the club had said he was "under the weather."
After the game, manager Craig Albernaz announced first baseman/designated hitter Ryan Mountcastle has a broken fourth metatarsal on his left foot. The 29-year-old was then placed on the 60-day IL prior to Monday night's opener vs. the D-backs.
The O's had an injury-plagued 2025 season, using the IL 39 times for 29 players while going 75-87 and finishing in last place in the American League East. Their fortune hasn't been any better during their 8-7 start in '26.
The only positive news to come on the injury front on Sunday was that catcher Adley Rutschman's MRI on his inflamed left ankle was "encouraging," per Albernaz, who indicated his stint on the 10-day IL could be brief.
"Just nip this in the bud, and then, he’ll be good to go," Albernaz said.
For O'Neill, this marks the 18th IL stint of his nine-year MLB career. After signing a three-year, $49.5 million deal with the Orioles prior to the 2025 season, he went on to play only 54 games during his first year in Baltimore, going on the IL three times (neck inflammation, left shoulder impingement, right wrist inflammation).
O'Neill has been on the concussion injured list once before -- from April 16-23, 2024, during his lone season with the Red Sox. Through 10 games this season, he was hitting .241 with one home run, four RBIs and a .698 OPS.
Albernaz said O'Neill had been battling an illness throughout the week. Then, on Thursday's off-day, he was "extremely dehydrated," which resulted in him fainting.
"We’re guessing that he probably banged his head a little bit. So that was the touch-and-go aspect of it, because we weren’t sure if it was the dehydration of the illness," Albernaz said. "And as he was getting worked up to play, he just felt dizzy. So, we’ve got to make sure he’s good to go."
As a corresponding move for O'Neill, Baltimore recalled outfielder Johnathan Rodríguez from Triple-A Norfolk. The 26-year-old, who was acquired in a trade with the Guardians on March 29, hit .333 (8-for-24) with one double and two RBIs over eight games for Norfolk, then drew a pinch-hit walk in the seventh on Sunday.
While O'Neill is sidelined, the Orioles are likely to use Taylor Ward, Colton Cowser and Dylan Beavers as the primary outfielders, with Leody Taveras getting occasional starts and Rodríguez serving as depth off the bench.
The O's filled Mountcastle's spot on the roster by selecting the contract of infielder/outfielder Weston Wilson from Triple-A. Wilson, 31, was hitting .195 with two homers and a .664 OPS through 12 games for Norfolk.
Albernaz again stated his belief in his players to get through this adversity, as they did Saturday and Sunday by winning two games against the Giants despite losing Rutschman, Mountcastle and O'Neill.
"To me, that’s the sign of a resilient group. And in this game, you have to be," Albernaz said. "The season’s too long, there are ups and downs, guys get injured. It’s all part of it. But the good teams can overcome that, and right now, we’re showing signs that we can. And I’d bet on this team a lot."
