Mariners Designate Miles Mastrobuoni For Assignment, Select Weston Wilson
The Mariners have selected the contract of infielder/outfielder Weston Wilson. Fellow infielder/outfielder Miles Mastrobuoni has been designated in a corresponding move. Prior to the official announcement, Adam Jude of The Seattle Times noted Wilson was in the clubhouse. Daniel Kramer of MLB.com indicated Mastrobuoni would likely be designated for assignment to make room.
Kramer suggests the swap is related to the fact that the Mariners are slated to face a bunch of lefties. The Red Sox are scheduled to start southpaws Ranger Suárez, Connelly Early and Payton Tolle this weekend. Seattle’s regular lineup is mostly filled with lefty bats, including J.P. Crawford, Josh Naylor, Dominic Canzone, Luke Raley, Cole Young and Colt Emerson. Righties Connor Joe and Rob Refsnyder are on the bench but Joe has a .189/.302/.324 line this year while Refsnyder is at .143/.214/.242.
Mastrobuoni and Wilson are both multi-positional types but the former hits from the left side and the latter the right. The 31-year-old Wilson has a .240/.331/.413 line in 291 plate appearances from 2023 to 2026, a line that translates to a 108 wRC+. That breaks down as a .248/.351/.456 line and 124 wRC+ against southpaws compared to a .229/.302/.352 line and 83 wRC+ in the other half of the split.
Defensively, Wilson has big league experience at every position on the diamond except for shortstop and catcher. Though he’s never played short in the big leagues, he has spent a decent amount of time there in the minors. He should give manager Dan Wilson a good amount of flexibility in trying to get through this gauntlet of lefties. He was with the Orioles earlier this year but got bumped from that club’s roster, allowing Seattle to sign him to a minor league deal this week.
After this Boston series, the Mariners play the Pirates, who have an all-righty rotation. Wilson is out of options, so perhaps he is in line for a short stay on the roster if the M’s want to shuffle things up again in a few days. Then again, Joe is still optionable and has been struggling, so sending him down could be another possibility.
Optimizing the roster will cost Mastrobuoni his spot. The 30-year-old is in his fifth big league season, having previously spent time with the Rays and Cubs. He was acquired by the Mariners in a cash deal in February of 2025 after being designated for assignment by Chicago. He has generally been a serviceable but light-hitting bench guy. From 2022 to 2024, he hit .231/.296/.276 in 447 plate appearances but played all four infield positions and the outfield corners.
He has barely gotten going this year. He started the season on the 10-day injured list due to a right calf strain. He was later transferred to the 60-day IL. He was activated a little over a week ago. He has a .217/.269/.217 line in 27 plate appearances since then.
Mastrobuoni exhausted his final option year in 2025, leaving him now out of options. He might have started the season on the roster bubble but the IL placement allowed him to technically linger in the mix for almost half the season, but he has now been bumped off.
DFA limbo can last as long as a week. The waiver process takes 48 hours, so the M’s could take as long as five days to explore trade interest. If he were to clear waivers, he would stay in the system as non-roster depth. He doesn’t have a previous career outright and is shy of three years of service, so he wouldn’t have the right to reject an outright assignment in favor of free agency.

Mariners Sign Weston Wilson To Minor League Contract
Infielder/outfielder Weston Wilson has signed a minor league contract with the Mariners after electing free agency in lieu of an outright assignment from the Orioles late last week. The team never formally announced the signing, but Wilson made his organizational debut with the Mariners’ Triple-A affiliate in Tacoma two days ago. He’s picked up a pair of three-hit games for the Rainiers already.
Wilson, 31, appeared in 21 games with the O’s and took 46 plate appearances prior to being designated for assignment. He hit .231/.348/.333 in that brief stretch, which marked his fourth season with some degree of major league experience. Wilson debuted with the 2023 Phillies and has totaled 291 plate appearances in the majors since. In that time, he’s slashed .240/.331/.413 — about 8% better than league-average production, by measure of wRC+.
Solid as that overall showing is, it came in frontloaded fashion. Wilson posted big numbers in brief auditions with the 2023-24 Phils before struggling to a .198/.282/.369 performance in a career-high 125 plate appearances with Philadelphia last year. He’s a right-handed hitter who’s batted .248/.351/.456 when facing lefties but just .229/.302/.352 against fellow righties.
Wilson has played first base, second base, third base and both outfield corners in the majors. He’s a career .248/.340/.462 hitter in parts of six minor league seasons. He gives the Mariners some righty-swinging depth at several positions and a generally productive Triple-A bat to round out the Tacoma roster. Seattle is currently without righty-swinging left fielder Randy Arozarena, lefty-hitting infielder/outfielder Brendan Donovan and righty-hitting utilityman Will Wilson (the latter of whom is reportedly weighing season-ending surgery).
At the moment, the Mariners are carrying a pair of veteran infield/outfield options on the bench: Rob Refsnyder and Connor Joe. Refsnyder has struggled greatly in his first season with the M’s. He signed a one-year, $6.25MM deal in free agency after a nice four-year run in Boston but has hit only .143/.214/.242 in 104 plate appearances. Joe is batting .189/.302/.324 in 43 plate appearances as a Mariner. Should either (or both) continue to struggle, it’s possible the Mariners could view the newly signed Wilson as a right-handed alternative off the bench.
Weston Wilson Elects Free Agency
The Orioles announced that utility player Weston Wilson elected free agency. Baltimore designated him for assignment last week when they selected catcher Sam Huff onto the MLB roster. Wilson cleared waivers and was outrighted for the second time in his career, which allowed him to test the market.
Wilson had spent the last two months on Baltimore’s MLB roster. He got some work at third base, mostly against left-handed pitching. Wilson tallied 46 plate appearances, hitting .231/.348/.333 with one home run. He worked six walks against 11 strikeouts. It was a decent enough showing for a bench player, but Baltimore needed to carry a third catcher with Adley Rutschman and Samuel Basallo nursing minor injuries.
The 31-year-old Wilson is out of options, so the O’s needed to send him through waivers. It stands to reason they’d like to bring him back on a minor league contract, though he’ll have the opportunity to explore other opportunities. Basallo and Rutschman have both returned to the lineup over the last two games, so the O’s theoretically could reverse the weekend transaction and sign Wilson to a big league deal.
Before this season, Wilson’s MLB experience came exclusively in Philadelphia. He played three years for the Phillies as an up-and-down platoon bat, hitting .242/.328/.428 across 245 trips to the plate. Wilson was mostly a corner outfielder with the Phils despite Baltimore using him most frequently on the dirt.
Orioles Designate Weston Wilson, Select Sam Huff
The Orioles announced that utilityman Weston Wilson has been designated for assignment. Taking Wilson’s place on both the 26-man and 40-man rosters is catcher Sam Huff, whose contract was selected from Triple-A Norfolk.
Huff’s arrival is related to the availability of Samuel Basallo, who made an early exit from Friday’s game due to what the team described as abdominal discomfort. The injury hasn’t yet been seemed serious enough to warrant a trip to the injured list, but even if Basallo is fine after a day or two of rest and recovery, the Orioles now have Huff on hand as a backup catcher behind Adley Rutschman.
Baltimore signed Huff to a minor league contract during the offseason, and his deal was previously selected to the active roster in April when Rutschman was on the 10-day IL. Huff appeared in three games for the O’s during his week on the 26-man roster before he was DFA’ed, and after Huff chose free agency over an outright assignment, he quickly re-signed with the Orioles on a fresh minors contract.
Should Basallo’s abdominal issue prove to be a short-term concern, it is very possible Huff will face another DFA within the next few days. Wilson is also no stranger to the DFA cycle, as he was designated and then outrighted off Baltimore’s 40-man roster last February, just a couple of weeks after the Orioles claimed him from the Phillies’ waiver wire. This past outright means that Wilson also has the ability to elect free agency over an outright assignment, assuming he clears waivers this time around.
Wilson’s contract was selected to the active roster on April 13, but he has seen only sporadic action in a backup role. Wilson has hit .231/.348/.333 in 46 plate appearances over 19 games, playing mostly at third base with one game in the outfield and three mop-up outings as a pitcher.
Now a veteran of the last four MLB seasons, Wilson has a .240/.331/.413 slash line over 291 career PA with the Orioles and Phillies. Wilson also has a good deal of experience at first and second base plus some work at the other two outfield positions, so he offers some versatility to any team looking to add bench depth on a waiver add.
Orioles Place Ryan Mountcastle On 60-Day IL, Select Weston Wilson
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.
Thairo Estrada Granted Release After Opting Out Of Orioles Deal
Veteran utilityman Thairo Estrada has been granted his release, the team announced. He had an opt-out provision in his minor league contract with Baltimore and is once again a free agent. The O’s also reassigned catcher Maverick Handley and outfielder Jhonkensy Noel to minor league camp. Both were non-roster invitees this spring.
Estrada, 30, went just 2-for-25 with a pair of singles and nine strikeouts this spring. It wasn’t the camp performance he was hoping for after a 2025 season in which he hit only .253/.285/.370 with the Rockies. Injuries limited Estrada to just 165 plate appearances a year ago. He missed time due to a broken wrist, a sprained thumb and a strained hamstring during a snakebit season.
From 2021 to 2023, Estrada slashed .266/.320/.416 with the Giants (105 wRC+). He eventually found himself upgraded from a utility role to the team’s starting second baseman. He combined that slightly above average bat with a strong glove to become a valuable player for San Francisco for a few years.
Things began to turn the wrong direction in 2024 — a season in which a left wrist sprain limited Estrada to just 96 games. He hit a paltry .217/.247/.343 (68 wRC+) even when he was healthy enough to take the field. The Giants cut him loose, and a one-year deal with the Rockies didn’t help him right the ship.
With Estrada being cut loose, the Orioles’ options for the final spot on Craig Albernaz’s bench include Jeremiah Jackson, Bryan Ramos and Weston Wilson. Jackson and Ramos are both on the 40-man roster. Jackson is hitting .333/.353/.545 in 34 spring plate appearances but has minor league options remaining. Ramos is hitting .297/.366/.459 in 41 plate appearances and is out of minor league options. Wilson has hit .241/.405/.448 and has the most outfield experience of the group.
Non-roster invitee Luis Vázquez had been in the running for a utility role as well, but Albernaz revealed this afternoon that Vázquez suffered a broken thumb yesterday when he was hit by a pitch (link via Andy Kostka of the Baltimore Banner). There’s no timetable for his return, but the ill-timed injury obviously takes him out of the running for a roster spot. He’ll stick with the O’s as a depth option and rehab the injury in their system.
Orioles Outright Weston Wilson
The Orioles announced they’ve outrighted infielder/outfielder Weston Wilson after he was designated for assignment over the weekend. Baltimore also confirmed they lost third baseman Bryan Ramos to the Cardinals via waivers, a move that was reported earlier this afternoon. Their 40-man roster count sits at 39, as Wilson’s DFA had already removed him from the tally.
Wilson actually lost his roster spot when Baltimore traded for Ramos, sending cash considerations to the White Sox. They quickly waived Ramos as well, so it seems they were hoping to stash both players at Triple-A Norfolk. That’s par for the course for Baltimore, the league’s most aggressive team at working the waiver wire. Wilson himself was claimed from Philadelphia at the end of January.
The 31-year-old Wilson has played parts of three MLB seasons, all with the Phillies. He has played in 100 games and taken 245 trips to the plate, hitting .242/.328/.428 with nine home runs. That’s slightly above-average production, but Philadelphia used the right-handed hitter in favorable situations. Nearly 60% of his career plate appearances have come against left-handed pitching. Wilson has taken nearly 1700 trips to the dish over five seasons in Triple-A, where he’s a .247/.339/.462 hitter.
This is Wilson’s first career outright assignment. He doesn’t have three years of service time, meaning he’ll have to accept. He’ll certainly get a non-roster invite to Spring Training when camps open next week and will try to play his way back onto the roster. A heavily right-handed bench isn’t doing him many favors, especially after the O’s acquired out-of-options infielder Blaze Alexander from Arizona yesterday.
Orioles Acquire Bryan Ramos, Designate Weston Wilson
The Orioles have acquired infielder Bryan Ramos from the White Sox, according to reporter Francys Romero. Baltimore has officially announced the trade, and the Sox will get cash considerations in return. To open up a 40-man spot for Ramos, the Orioles designated Weston Wilson for assignment.
Ramos was designated for assignment three days ago when the Sox themselves needed to create 40-man space for the newly-signed Seranthony Dominguez. Ramos’ stint in DFA limbo didn’t last long, and he’ll now change organizations for the first time in his career, as the infielder was an international signing for the White Sox back in 2018. He started to make waves as a prospect during the 2022-23 seasons, and he made his MLB debut in 2024, posting a .586 OPS over 108 plate appearances for Chicago.
This uninspiring performance seemed to drop Ramos down the depth chart, even on a rebuilding White Sox team. He appeared in just four big league games in 2025, bringing his overall slash line to .198/.244/.333 in 120 PA against Major League pitching. While Ramos’ numbers (.235/.321/.404 in 705 PA) at Triple-A Charlotte are more respectable, they’re underwhelming considering that Charlotte plays in one of the most hitter-friendly ballparks in the minors.
Ramos has played only third base in the majors, and the hot corner has also been his primary position during his minor league career. However, Ramos has increased his versatility by playing some second base and a handful of games as a first baseman and left fielder, as becoming more of a utilityman will help Ramos in his attempts to return to the majors.
Wilson is a more established utilityman who has seen some time at first base, second base, third base, and all three outfield positions over his 100 career Major League games, all with the Phillies from 2023-25. Wilson has also shown more at the plate, with a .242/.328/.428 and nine homers over 245 PA. Most of that production came in Wilson’s first two seasons, and since he had only a .652 OPS over 125 PA in 2025, the Phils decided to move on by DFA’ing Wilson in late January.
The Orioles made a claim a few days later, but have now sent Wilson back to the waiver wire in relatively short order. This is something of the way of life for players like Wilson or Ramos who are out of minor league options, and Baltimore is particularly aggressive in constantly churning the back end of its 40-man roster, with the idea that the O’s can add minor league depth by sneaking enough players through the outright process. Assuming Wilson isn’t claimed again, the Orioles can outright him to Triple-A since Wilson doesn’t have enough service time to reject an outright assignment.
Orioles Claim Weston Wilson, Designate José Suarez
The Orioles have claimed utilityman Weston Wilson off waivers from the Phillies and designated left-hander José Suarez for assignment, reports Ari Alexander of 7 News.
Wilson, 31, was designated for assignment by the Phillies last week when they re-signed J.T. Realmuto. He’s spent parts of the past three seasons in the majors with them, 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 this past season 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.
He’s played all around the diamond, but despite occasional reps in the middle infield, Wilson is primarily a corner infielder/outfielder. He’ll give the O’s some righty-swinging depth at all four corner spots, but he’s also out of minor league options, which significantly hinders his chances of sticking on the roster. He’d need to break camp on the club or else be designated for assignment once again.
The Orioles are as aggressive as any team in the sport when it comes to claiming players off waivers and then trying to pass them through waivers themselves in order to cultivate depth. Suárez, who’s being designated for assignment, is a product of that very churn. It should come as no surprise to anyone if Wilson is designated for assignment in the near future, whenever the O’s make their next waiver addition or sign their next free agent. At that point, they’d hope to outright him and keep him in Triple-A.
Baltimore claimed Suarez just one week ago, plucking him off waivers from the Braves, who’d signed him to a $900K deal to avoid arbitration. He’s out of minor league options, so simply optioning him to Triple-A Norfolk was never in the cards. The O’s will hope to sneak him through waivers and stash him in Triple-A as depth. Suarez has enough service time to reject an outright assignment, but doing so would mean forfeiting the $900K base salary on the big league portion of his deal (and any notable minor league split he secured as well).
Injuries limited Suarez to 19 1/3 innings this past season, but he posted a sharp 1.86 ERA in that time — albeit with a less-encouraging 16-to-10 K/BB ratio. The 28-year-old has started 62 games and made another 44 relief appearances in a career that’s seen him amass 396 innings with a 5.30 earned run average. Suarez posted disastrous numbers with the Angels in 2020, 2023 and 2024 but was a strong swingman for them in 2021-22. During those two seasons, he logged 207 1/3 frames with a 3.86 ERA, 21.5% strikeout rate and 7.9% walk rate.
The Orioles can trade Suarez or place him on outright waivers at any point within the next five days. Waivers are a 48-hour process. His DFA will be resolved by next Thursday afternoon.
Phillies Designate Weston Wilson For Assignment
The Phillies announced this morning that they’ve designated infielder Weston Wilson for assignment. The move makes room for veteran catcher J.T. Realmuto, whose new contract with Philadelphia is now official, on the 40-man roster.
Wilson, 31, has appeared in 100 games for the Phillies over the past three seasons while being used in an up-and-down bench role. He’s slashed a respectable .242/.328/.428 (109 wRC+) across 245 career trips to the plate in the big leagues, with eight stolen bases and nine homers. That’s decent enough production from a bench player, and Wilson has paired it with decent versatility. While he’s primarily played left field in the majors, he’s also received time at second base, third base, first base, and right field. He’s also seen time at shortstop in the minors previously, though that was not the case this past year.
That combination of versatility and a solid resume in the big leagues might make Wilson seem like a very attractive bench piece, but a tough 2025 season casts doubt on that assessment. When looking exclusively at this most recent campaign, Wilson hit just .198/.282/.369 (81 wRC+) in the majors across 54 games. Underlying metrics, including a 10.3% barrel rate, an unusually low .236 BABIP, and a .333 xwOBA that significantly outpaces his .288 wOBA all suggest that Wilson may have some poor fortune baked into those weak numbers, particularly given that his strikeout (27.2%) and walk (9.6%) rates were both improved relative to 2024.
Those signs that positive regression could be on the way, in conjunction with Wilson’s career 130 wRC+ against left-handed pitching, make it easy to think that Wilson could hold down a bench role at the big league level. That didn’t allow him to hold onto his roster spot in Philadelphia, however, as Otto Kemp and Edmundo Sosa are both ahead of him on the team’s depth chart when it comes to right-handed utility players. In previous years, the Phillies would’ve surely held onto Wilson and kept him on the roster as optionable depth, but Philadelphia used Wilson’s last option year in 2025 and would now need to pass Wilson through waivers in order to send him to the minors anyway.
They’re getting that process underway now. They’ll have one week to either work out a trade involving Wilson or put him through the waiver wire. Should Wilson clear waivers, the Phillies would likely outright him to the minor leagues where he could serve as non-roster depth for the club headed into 2026. Given Wilson’s solid numbers at the big league level, however, it seems likely that a team will be interested in rolling the dice on him. That could come in the form of a simple waiver claim, or perhaps a minor trade if a team is interested enough in Wilson to try and work out a deal with Philadelphia directly.
