The Orioles announced a number of roster moves today. Outfielder Cedric Mullins and infielder Jordan Westburg have both been reinstated from the 10-day injured list. In corresponding moves, the club has optioned outfielder Heston Kjerstad and designated infielder Emmanuel Rivera for assignment. The O’s also announced that outfielder Jordyn Adams, who was designated for assignment last week, has been sent outright to Triple-A Norfolk. The 40-man roster count drops to 38.
Kjerstad, 26, was the No. 2 overall pick back in 2020, though that selection represented a bit of draft-day creativity; he was generally viewed as a mid-first-round talent but signed with the O’s on an underslot deal at No. 2 overall, leaving Baltimore some extra money to pursue over-slot bonuses with others further down the line — the aforementioned Westburg and top prospect Coby Mayo among them.
The Orioles have given Kjerstad looks in each of the past three seasons now, but the 2025 campaign is the first where he’s been given a real run at anything close to regular playing time. It didn’t go well. Despite being largely shielded from left-handed pitching, the lefty-swinging Kjerstad hit just .192/.240/.327 with four homers, a 3.6% walk rate and a 26.9% strikeout rate in 167 turns at the plate. He’s improved his overall contact rate relative to 2023-24, but he’s chasing off the plate at borderline egregious levels (38.4% chase rate) and still swinging through pitches too often.
Kjerstad finds himself at something of a crossroads with the Orioles. He’ll still have one more minor league option remaining beyond the current season, but he’s now struggled to establish himself in three separate seasons. Colton Cowser is locked into one outfield spot long-term. Tyler O’Neill has an opt-out clause in his three-year contract that he does not presently appear likely to take (although a big finish to the season can always change that). Mullins is a free agent at season’s end, as is Ryan O’Hearn, which could open some outfield/designated hitter playing time. However, the O’s have prospects like Enrique Bradfield Jr., Jud Fabian, Vance Honeycutt and Dylan Beavers rising through the system — any of whom could also factor into those competitions for playing time.
It’s arguable that Kjerstad hasn’t really gotten a fair audition. He’s totaled 314 MLB plate appearances across three seasons and always been either platooned or had the specter of someone returning from the IL to take his spot and push him back to Triple-A Norfolk.
Other clubs might have given him a more traditional everyday opportunity, but the Orioles tend to prioritize matchups more than most and have frequently brought in veteran outfielders who’ve cut into Kjerstad’s potential playing time (e.g. O’Neill, Ramon Laureano, Dylan Carlson, Eloy Jimenez, Austin Slater). They make no secret about their endeavors to stockpile as much depth as possible, which positions them well for injuries but also results in scattershot opportunities for young players like Kjerstad, Mayo and since-traded prospects like Kyle Stowers, Connor Norby and Joey Ortiz.
For now, Kjerstad will head to Norfolk and look to get his swing back on track. However, he has little left to prove against Triple-A pitching. Kjerstad has played 132 games there, taken 591 plate appearances, and mashed at a .299/.382/.541 clip.
As for Rivera, he originally came to the O’s as one of those previously mentioned depth grabs. Baltimore claimed him off waivers last August, enjoyed a productive run of 27 games down the stretch, and tendered him a $1MM contract over the winter. Rivera never seemed likely to replicate the .364 average on balls in play or 22.2% homer-to-fly-ball ratio he logged with the O’s in 2024, however, and his offense has plummeted back down to his career norms in 2025. He’s taken 76 plate appearances and batted .232/.303/.275 — not far off his lifetime .243/.306/.363 slash in the majors.
The 28-year-old Rivera’s hard-contact numbers completely eroded this season. He’s a surehanded defender at the hot corner and has also played some first base in the majors. However, he’s out of minor league options, so the O’s couldn’t simply send him down. He’ll first need to clear waivers. Given his lack of track record and options, he could well pass through unclaimed, though he’s affordable enough that a team seeking short-term help at the hot corner could look to him as a stopgap between now and the trade deadline.
MLB rules stipulate that a player can be in DFA limbo for a maximum of one week, and waivers are a 48-hour process, so Rivera will be traded or placed on waivers within the next five days. If he clears, he’ll presumably accept a minor league assignment, as he did when the O’s passed him through waivers earlier this spring. Rejecting in favor of free agency would mean forfeiting the remainder of his $1MM guarantee, as Rivera does not have the five years of service needed to reject an outright assignment and retain his guaranteed salary.
