4:12pm: The Orioles officially announced that Wilson’s contract has been selected and that Mountcastle has been placed on the 60-day IL. That’s one of just several moves for the O’s today. Baltimore also recalled righty Dean Kremer earlier today and just announced the acquisition of corner infielder Christian Encarnacion-Strand in a cash swap with the Reds.
3:43pm: Orioles first baseman/designated hitter Ryan Mountcastle is headed to the injured list after suffering a broken fourth metacarpal in his left foot while legging out a double this past weekend, manager Craig Albernaz tells the Baltimore beat (link via MASNsports.com’s Roch Kubatko). Albernaz didn’t tip the team’s hand on whether Mountcastle would head to the 10-day or 60-day IL, suggesting only that both are under consideration. He added that he has not yet been told whether surgery is on the table.
Kubatko adds that infielder/outfielder Weston Wilson is on the Orioles’ taxi squad at the moment, making him a likely replacement, though the team hasn’t announced anything on that front. Jackson Holliday is with the club today at Camden Yards but is not yet ready for reinstatement from the IL. He’s merely taking some infield drills while Triple-A Norfolk is off. Holliday has yet to play this season after suffering a hamate fracture early in spring training.
Wilson isn’t on the 40-man roster, so assuming he is indeed the corresponding move, he’d need to have his contract selected. The Orioles have a full 40-man roster, though if Mountcastle heads to the 60-day IL, that’d open a spot.
The 29-year-old Mountcastle has hit decently in a far more limited role than he’s used to so far in 2026. He’s appeared in eight games and tallied only 15 plate appearances, going 4-for-14 with a double and a walk in that time. Baltimore’s signing of Pete Alonso and the ascension of catcher/designated hitter Samuel Basallo has substantially cut into Mountcastle’s playing time.
Even before the O’s signed Alonso, Mountcastle looked like a prime non-tender candidate. Injuries limited him to 89 games last season, and he slashed just .250/.286/.367 (81 wRC+) when healthy. He was due for one final raise in arbitration, and with a $6.787MM salary last year, he felt like a relatively pricey rebound candidate, given his limited defensive utility. Baltimore also had longtime top prospect Coby Mayo ready for a full-time run at first base (though obviously the Alonso signing changed that calculus).
The Orioles made the somewhat surprising call to tender him. They wound up coaxing some additional value by getting Mountcastle to agree to repeat his 2025 salary and tack on a $7.5MM club option for what should’ve been his first free agent year in 2026. However, Mountcastle still entered camp with a “square peg in a round hole” vibe as a clearly imperfect fit for an Orioles roster that had changed considerably since his run as a regular in the middle of the order. Unsurprisingly, the O’s looked into various trade possibilities throughout spring training, but no deal came together.
Mountcastle now heads to the injured list for a potentially prolonged absence. He’ll join third baseman Jordan Westburg, who’s hoping to avoid Tommy John surgery after being diagnosed with a UCL tear, in that regard. With Westburg sidelined, the aforementioned Mayo has been manning the hot corner but has struggled with the bat. An absence of some note for Mountcastle could give Mayo a longer leash to get right at the plate even when Holliday and possibly Westburg return to the fold.
Wilson, 31, was an offseason waiver claim out of the Phillies organization. He’s spent parts of the past three seasons in the majors with Philadelphia, hitting a combined .242/.328/.428 with nine home runs in 245 trips to the plate. Almost all of that production came in 2023-24, however. Wilson hit just .198/.282/.369 in a career-high 125 plate appearances in 2025 but raked at a .288/.375/.490 clip the prior two seasons.
Wilson has never hit righties much but feasted on southpaws in ’23-’24 before taking a huge step back in ’25. Even with last year’s lack of production in platoon settings, he’s a career .250/.359/.475 hitter (130 wRC+) against left-handed pitching. Wilson also owns a solid .247/.339/.462 output in nearly 1700 plate appearances of Triple-A work and will give Baltimore an option at all four corner positions. He batted .233/.395/.433 in 36 spring plate appearances but has mustered only a .195/.298/.366 slash in a comparable sample at Triple-A this year.
