Orioles Notes: Mountcastle, Mayo

Orioles first baseman/designated hitter Ryan Mountcastle was lifted from the eighth inning of today’s Grapefruit League contest after being plunked on the right hand, but the team has already announced that initial x-rays came back negative. Mountcastle will presumably be considered day-to-day for the time being.

A fracture or any sort of notable injury would only have piled on to what’s been an injury-marred camp for the Orioles this spring in Sarasota. Baltimore has already lost Jordan Westburg (partial UCL tear), Jackson Holliday (hamate fracture) and Andrew Kittredge (shoulder inflammation).

The offseason signing of Pete Alonso pushed Mountcastle out of an everyday role in Baltimore, but he’s still in the mix for DH reps and occasional time at first base. Injuries to Westburg and Holliday have thrust Coby Mayo (third base) and trade acquisition Blaze Alexander (second base) into likely starting jobs. Those injuries create more opportunity for both Mountcastle and catcher/first baseman Samuel Basallo at the DH spot.

Of course, that assumes Mountcastle breaks camp with the club at all. He didn’t seem like a lock to be tendered a contract coming off an injury-ruined season in 2025, but the O’s passed on their chance to cut him loose. After tendering him a contract, they agreed to a one-year deal worth $6.72MM — a contract that includes a 2027 club option that gave the O’s control over what would’ve been Mountcastle’s first free agent season.

The O’s shopped Mountcastle throughout the offseason and have continued to discuss him during spring trade scenarios. The injuries elsewhere on the roster perhaps make a Mountcastle trade a bit less likely, but an injury of his own would have all but eliminated the possibility. With today’s clean bill of health, it seems like an eventual move could at least plausibly be on the table. MLBTR’s Anthony Franco took a look at some logical landing spots for Mountcastle just last week.

The early spate of injuries has already prompted the Orioles to pump the brakes on a potential trade of the aforementioned Mayo. He’s seen his name kicked around the rumor circuit for the better part of 18 months, but Mayo now appears poised to open the season at the hot corner. Kyle Goon of the Baltimore Banner takes a look at the wild ride Mayo has been on over the past year, being asked to change positions multiple times and slowly feeling as though his standing in the organization was slipping.

Mayo played shortstop prior to being drafted, was quickly moved to third base, and was told following the 2025 season that he should prepare strictly as a first baseman — the position he played down the stretch with regularity last year. He then watched the Orioles sign Alonso to a five-year contract, retain Mountcastle in arbitration and effectively ensure that Basallo would be on the roster moving forward by signing him to an eight-year extension.

“I think you just have to remember that there’s a plan out there for you, no matter if it was with the Orioles or with another team,” Mayo said of the tumultuous run he’s had over the past year-plus. “I’m gonna always do what I can to help myself out and get better. There’s nothing to gain out of sulking and being upset about moves a team has made. Going into the spring, who knew that we were gonna have two guys go down in a weeklong span? Like, we had no idea.”

New O’s skipper Craig Albernaz tells Goon that he’s “more than comfortable” opening the year with Mayo as his primary third baseman. In all likelihood, that’ll be the plan. Mayo has made three errors back at the hot corner but has hit well enough to overshadow those concerns for the time being. He was out of the lineup today, but Mayo is 13-for-26 with three doubles, a homer and only one strikeout in 28 spring plate appearances. He also hasn’t taken a walk, leading to an oddball line with his OBP checking in south of his batting average: .500/.464/.731. (Mayo has two sacrifice flies on the spring, hence the OBP discrepancy.)
