Orioles Designate Matt Bowman For Assignment

By | at

The Orioles announced that right-hander Matt Bowman has been designated for assignment.  The move opens up a roster spot for fellow righty Scott Blewett, who was acquired from the Braves in a cash deal two days ago.

Bowman is no stranger to the waiver wire, as this is the second time the Orioles have DFA’ed him this season, and he bounced around the league several times in 2024 and ended up pitching for four different teams at the MLB level.  His previous designation and outright back in May saw Bowman accept the outright assignment off the 40-man roster, though he has the right to reject any future outright in favor of free agency.

It remains to be seen if Bowman will again stay put if he clears waivers and is outrighted this time.  Bouncing up and down between Triple-A and the big leagues within one organization might carry more appeal for Bowman than his four-club experience in 2024, and since Bowman is out of minor league options, he isn’t likely to gain more roster security on other team.

In between the roster moves, Bowman has a 4.57 ERA over 21 2/3 innings and 18 relief appearances for Baltimore this season, posting a solid 5.3% walk rate but also an uninspiring 16.8% strikeout rate.  Bowman’s latest stint on the O’s roster ended on a high note, as he tossed 2 1/3 innings of hitless shutout ball in the Orioles’ 7-4 win over the Athletics yesterday.

Ryan Mountcastle To Miss 8-12 Weeks

By | at

The Orioles will be without first baseman Ryan Mountcastle for 8-12 weeks after imaging revealed a Grade 2 strain of his right hamstring, interim manager Tony Mansolino told reporters (including MLB.com’s Jake Rill). Baltimore placed him on the 10-day injured list and recalled Coby Mayo last week. Mountcastle’s injury is significant enough that he’ll eventually be moved to the 60-day IL when the team needs to create a 40-man roster spot.

A Grade 2 strain is viewed of “moderate” severity and involves a partial muscle tear. It’s the biggest blow in what has been a frustrating season for the 28-year-old infielder. Mountcastle has hit .246/.280/.348 with only two home runs across 200 plate appearances. Those would be career-worst numbers across the board. Mountcastle has been a slightly better than average hitter for most of his five-year MLB career. Last season’s .271/.308/.425 showing is more representative of his overall body of work.

This very likely takes him off the board as a trade candidate. Even a return at the short end of the timeline would be after the July 31 deadline. Injured players can be traded, but Baltimore would be hard-pressed to find interest between the rough first couple months and the extended absence. Mountcastle is playing on a $6.787MM salary and will surpass the five-year service threshold. He’ll be eligible for arbitration once more next winter, but a projected $7MM+ sum figures to make him a non-tender candidate. That’d be particularly true if the recovery carries towards the back end of the timeline and keeps him out into September.

Ryan O’Hearn has outperformed Mountcastle this season and had already taken the first base job. Mayo has been playing regularly between first base and designated hitter for the past week. The O’s activated Ramón Laureano from the injured list this afternoon. He’s in tonight at DH against A’s lefty JP Sears. Baltimore should also welcome Jordan Westburg and Gary Sánchez back relatively soon. Both players are on rehab stints at Triple-A Norfolk.

Orioles Acquire Scott Blewett

By | at

The Orioles announced that they have acquired right-hander Scott Blewett from the Braves in exchange for cash considerations. Outfielder Jordyn Adams has been designated for assignment to open a 40-man spot. Fellow outfielder Ramón Laureano has been reinstated from the 10-day injured list and takes the active roster spot vacated by Adams. Blewett has not yet reported to the team and is therefore not on the active roster yet, so a spot will have to be opened for him when he does link up with the O’s.

It was reported yesterday that Atlanta was going to designate Blewett for assignment but it seems they lined up a trade before even getting around to that DFA. Blewett played a key role in yesterday’s heartbreaking loss in Atlanta. He entered the game in the top of the eighth, with Atlanta leading 9-3. He got through that inning while allowing one run, but Atlanta got that back in the bottom of the eighth. That left them with a 10-4 leading starting the ninth. Blewett stayed in and retired the first batter of that inning but the next four reached. Closer Raisel Iglesias was drawn into the 10-7 game and it quickly became 11-10 for the Diamondbacks.

Blewett was charged with five earned runs in an inning and a third. The sting of the loss seems to have prompted a bit of a shakeup, with Atlanta calling up Craig Kimbrel from the minors. That bumped Blewett off the roster but he’s actually been having a pretty decent season on the whole.

Even including yesterday’s unpleasantness, Blewett has a passable 3.91 earned run average in 2025. His 21.8% strikeout rate and 10% walk rate are close to average while his 56.3% ground ball rate is quite strong.

Blewett is out of options but is clearly valued around the league, as he keeps passing from club to club. He started this year with the Twins on a minor league deal. He was called up in April but designated for assignment a few days later. He was claimed by the Orioles but received another DFA a few days after that. He was sent to Atlanta in a cash deal, which led to him holding a roster spot for more than a month, though he’s now on the move again.

Adams, 25, signed a minor league deal with the O’s in the offseason. He was called up to the big leagues a week ago as the O’s were dealing with a number of position player injuries. He’s essentially been used as a defensive replacement since then, getting into five games but only making one plate appearance.

A former first-round pick of the Angels, Adams is considered an excellent athlete but he hasn’t been able to handle pitching since reaching the higher minor league levels. Dating back to the start of 2021, he has stepped to the plate almost 2,000 times on the farm with a .247/.326/.377 line and 84 wRC+. He has enough speed to steal 20 to 40 bases annually and run balls down in the outfield.

He’ll now head into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the O’s could take as long as five days to explore trade interest. He does have one option year remaining.

Cooper Hummel Elects Free Agency

By | at

The Orioles yet again announced that outfielder/first baseman Cooper Hummel elected free agency after going unclaimed on outright waivers. He was designated for assignment on Monday when Colton Cowser returned from the injured list.

Hummel had two stints in Baltimore that lasted a combined four days. He signed an MLB deal with the O’s after opting out of a non-roster contract with the Yankees. They designated him for assignment a day later when they needed a third catcher. He cleared waivers and re-signed on a fresh major league deal. Hummel spent three more days on the active roster. He struck out in his only at-bat and played two innings in right field.

It has presumably been a frustrating sequence, but Hummel picked up a little over a week of big league pay between his stint on the active roster and in DFA limbo. He’ll now return to the market and should at least find another minor league deal if no team is willing to plug him directly onto the MLB roster.

The switch-hitting Hummel appeared in 66 MLB contests for the Diamondbacks during his 2022 rookie season. He’s only made 17 big league appearances in the two-plus years since then. A career .159/.254/.274 hitter, he’s shown more offensive ability in the minors. Hummel has a .284/.419/.475 slash line over parts of five Triple-A seasons. He reached base at a .415 clip in 10 games with the Yankees’ affiliate before opting out.

Orioles Re-Sign Chadwick Tromp To Minor League Deal

By | at

The Orioles announced to reporters, including Roch Kubatko of MASNsports.com, that catcher Chadwick Tromp has been re-signed to a minor league deal. He is with the club in Seattle and on the taxi squad.

Tromp, 30, was on the O’s roster for a few days recently. Adley Rutschman got a concussion scare, so the O’s added Tromp in order to have another backstop on the roster alongside Maverick Handley. Rutschman felt better a few days later, which led to the out-of-options Tromp being designated for assignment. He went hitless in four plate appearances during that brief stint as an Oriole. He elected free agency just a few hours ago but he and the club have worked out a new pact.

There hasn’t been anything to suggest that there’s anything currently wrong with Rutschman or Handley, so it’s possible Tromp is just around on the taxi squad for logistical reasons. The Orioles are in Seattle for three games and then play three against the Athletics in West Sacramento. The Triple-A Norfolk Tides are in Louisville, Kentucky this week, so it would take some time to get a fresh body to the West Coast if an injury did pop up. Tromp’s presence gives them someone on hand who can be added to the roster on short notice.

The O’s go back home next week after facing the A’s, at which point Tromp could perhaps join the Tides. He hasn’t hit much in his big league career, with a .219/.229/.375 line in part-time play over six seasons, but he has a solid defensive reputation and better offense in the minors. He has a combined .256/.337/.427 line and 102 wRC+ in 872 Triple-A plate appearances dating back to the start of the 2022 season.

Chadwick Tromp Elects Free Agency

By | at

The Orioles announced that catcher Chadwick Tromp has elected free agency in lieu of accepting an outright assignment to Triple-A Norfolk. That indicates he cleared waivers after being designated for assignment a few days ago.

Tromp, 30, had a very brief stint on Baltimore’s roster. Catcher Adley Rutschman had a concussion scare last week, leaving Maverick Handley as the only healthy backstop on the roster. That prompted the club to add Tromp. However, Rutschman quickly recovered, which led to Tromp getting bumped right back off. Since he is out of options, Baltimore had little choice but to designate him for assignment. He appeared in two games for the O’s, going hitless in four plate appearances.

A player with a previous career outright assignment has the right to elect free agency. This is the second time this year that Tromp has exercised that right. He started the year with Atlanta but had a tenuous hold on a roster spot since he burned his final option season in 2024. Sean Murphy started the season on the injured list, which got prospect Drake Baldwin to the majors. Murphy got healthy in the first week of April, sending Tromp into DFA limbo. He cleared waivers, elected free agency and signed a minor league deal with the O’s.

He’s now likely to get another minor league deal somewhere in the coming days, perhaps even returning to the Orioles. The fact that he cleared waivers suggests that no club is currently willing to give him a big league spot.

Tromp has 63 games of big league experience now, spread across six different seasons. He has a tepid .219/.229/.375 batting line over those campaigns. His glovework has generally received solid grades and he has shown more offensive potential in the minors. Dating back to the start of the 2022 season, he has a .256/.337/.427 line and 102 wRC+ in 872 Triple-A plate appearances.

Orioles Reinstate Colton Cowser From 60-Day IL, Designate Cooper Hummel For Assignment

By | at

The Orioles announced that outfielder Colton Cowser has been reinstated from the 60-day injured list. In a corresponding move, infielder/outfielder Cooper Hummel has been designated for assignment.

The O’s have been without Cowser for almost the entire year. In just the fourth game of the season, he slid into first base and suffered a fractured left thumb. The Orioles announced that he would probably miss six to eight weeks. He has gone just beyond that, as today is nine weeks since he suffered that injury.

While he’s been gone, the club has been struggling badly. Even though they just swept the White Sox over the weekend, they sport a record of 22-36, with the Sox the only club below them in the American League standings.

That is perhaps at least somewhat due to Cowser’s absence. Last year, he hit 24 home runs for the O’s and swiped nine bases. His 30.7% strikeout rate was quite high but he also drew walks at a solid 9.3% clip. He got strong marks for his outfield glovework, playing all three spots. FanGraphs credited him with four wins above replacement and he finished second to Luis Gil in American League Rookie of the Year voting.

Getting that player back in the lineup is nice but the O’s have a steep hill to climb. They’re also not at full strength in the outfield as Cedric Mullins, Tyler O’Neill and Ramón Laureano are all still on the shelf. Those absences make Cowser’s return a very welcome sight for Baltimore fans. He’ll join an outfield mix that currently consists of Heston Kjerstad, Dylan Carlson, Ryan O’Hearn, Jordyn Adams and Jorge Mateo.

As for Hummel, this is the latest transaction in what has surely been a frustrating week-plus for him. The O’s signed him on May 25th, after he had opted out of a minor league deal with the Yankees. He was designated for assignment the next day, without appearing in a game. Catcher Adley Rutschman had a concussion scare and the O’s needed to give that roster spot to Chadwick Tromp. A few days later, with Rutschman feeling better, Hummel was re-signed on May 30th.

But he’s now heading into DFA limbo yet again. Around all the transactions, he has just one plate appearance as an Oriole. He pinch hit for Ryan Mountcastle on Friday and struck out. It’s a bit of a microcosm for Hummel’s entire career, as he has always performed well in the minors but hasn’t been given many big league chances. Dating back to the start of 2021, he has a .284/.419/.475 line and 132 wRC+ at the Triple-A level. Despite that strong output, he hasn’t received more than 26 big league plate appearances in a season since 2022.

He’ll head back into DFA limbo for a week at most. He just cleared waivers last week and seems likely to do so again. If that comes to pass, he will have the right to elect free agency as a player with a previous career outright.

Cionel Perez Accepts Outright Assignment

By | at

The Orioles announced this evening that left-hander Cionel Perez has cleared waivers and accepted an outright assignment to Triple-A Norfolk. He’ll report to the minors and be utilized as a non-roster depth option going forward.

Perez, 29, came up to the big leagues with the Astros back in 2018. He ultimately didn’t get much run with the club, serving as an up-and-down piece for Houston across three seasons with the club where he posted a 5.74 ERA in 26 2/3 innings of work. An equally disappointing and short-lived stint with the Reds followed in 2021, but ahead of the 2022 season Perez was plucked off waivers by the Orioles and placed into their bullpen mix for the coming year.

Once given regular reps on a club that entered the year still in the midst of a rebuild, Perez began to blossom. The lefty enjoyed the best season of his career in 2022 as he pitched to a sterling 1.40 ERA (278 ERA+) with a 2.80 FIP in 57 2/3 frames. A 23.5% strikeout rate and a 9.0% walk rate were both solid figures, but what made Perez truly stand out was his ability to keep the ball in the park. A 51.3% ground ball rate proved to be a big part of that, but Perez’s 4.3% home run to fly ball ratio appeared unsustainable from the jump. That made it far from surprising when his results regressed the following year, though he still remained an effective reliever with a 3.54 ERA and 3.84 FIP in 65 appearances.

Things started to take a turn for the worse last year, however. Despite peripheral numbers that were generally about the same or better as compared to 2023, Perez’s 2024 season saw his ERA balloon all the way up to 4.53. Perez’s strikeout and walk rates had slipped incrementally over the past two years and now sat at a lackluster 19.3% and 11.8%, respectively. While his 55.8% grounder rate and continued ability to avoid allowing home runs was enough to inspire some optimism about the possibility of a return to form in 2025, those hopes were quickly snuffed out by his early-season performance. Perez pitched to an 8.31 ERA with a 5.71 FIP across 21 2/3 innings of work this year before the Orioles decided to pull the plug last week.

Between those brutal results and a $2.2MM salary for 2025, it’s hardly a shock that no club opted to claim the lefty off waivers and try to help him improve his results going forward. Perhaps a club will view him as a low-cost reclamation project in the offseason when he won’t come with such an expensive price tag, assuming he hasn’t already turned things around by then. For now, Perez figures to attempt to get right at the Triple-A level in hopes of being utilized in the big league bullpen once again later this year. The floundering Orioles are appearing increasingly certain to sell at least some pieces at the trade deadline, so if the club fails to turn things around it’s not hard to imagine Perez getting another opportunity after the trade deadline if Baltimore parts ways with some of the pitchers currently in their bullpen mix.

Orioles Place Ryan Mountcastle On 10-Day IL, Recall Coby Mayo

By | at

The Orioles announced four roster moves Saturday, including the news that first baseman Ryan Mountcastle has been placed on the 10-day injured list due to a right hamstring strain.  Top infield prospect Coby Mayo has been called up from Triple-A Norfolk, and outfielder Jordyn Adams is also heading up from Triple-A after his contract was selected to Baltimore’s active roster.  To create space on the 40-man roster, catcher Chadwick Tromp was designated for assignment.

Mountcastle stole home for what ended up as the winning run in the Orioles’ 2-1 win over the White Sox yesterday, but the first baseman left the game a couple of innings later due to what was described just as discomfort in his hamstring.  The severity of the strain isn’t yet known, as interim manager Tony Mansolino told reporters (including Matt Weyrich of the Baltimore Sun) that Mountcastle would be undergoing an MRI today.

Like much of the Orioles roster, Mountcastle has gotten off to a rough start in 2025, with just a .246/.280/.348 slash line to show for 200 plate appearances.  It is a huge dropoff from the generally solid (112 wRC+) production Mountcastle posted over his first five seasons as a regular in the O’s lineup.  Mountcastle has traditionally hit with enough power to overcome subpar walk and strikeout totals, but while his barrel and barrel rates are at his career norms, his Isolated Power is only .102 (far below his .185 career number prior to 2025).

This IL stint could be viewed as a potential reset for Mountcastle’s season in this context, and his absence gives Mayo another shot at establishing himself at the MLB level.  Mayo has been called up for a few limited stints in the majors over the last two seasons, and has hit only .094/.186/.094 over 59 PA against big league pitching.  Even these extreme struggles can be written off as a small sample size, though Mayo’s domination of Triple-A pitching has also fallen off this year, as he has a modest .226/.318/.452 slash over 195 PA in Norfolk.

It is obviously far too soon to write off a player who has gone from being a fourth-round pick in the 2020 draft to a fixture on top-100 prospect lists.  Mayo hasn’t gotten much playing time with Baltimore due to the team’s crowded infield, yet perhaps in monkey’s paw fashion, some opportunity has now arisen due to the Orioles’ disastrous start and the swath of injuries that have taken out most of the everyday lineup.

Mountcastle joins Jordan Westburg, Colton Cowser, Cedric Mullins, Tyler O’Neill, Gary Sanchez, and Ramon Laureano on the long list of Orioles position players on the IL.  Between this group and several pitchers also sidelined, the Orioles haven’t been able to make up the depth in stumbling to a 20-36 record.

Westburg and Cowser are both on Triple-A rehab assignments and could be back in relatively short order.  With Mullins hitting the IL yesterday, however, the Orioles will shore up their outfield by adding Adams, who inked a minor league contract with the team over the offseason.

Adams has hit only .212/.316/.345 in 136 PA at Triple-A this season, and his big league track record consists of a .176/.205/.216 slash line in 78 PA with the Angels over the 2023-24 seasons.  A former first-rounder who received some top-100 attention during his time in the Halos’ farm system, Adams can play all three outfield positions, and is a decent bench option to have on hand until Cowser returns.

Tromp was also a minor league signing in April, and he was selected to the MLB roster earlier this week due to concerns that Adley Rutschman might have required a stint on the seven-day concussion-related IL.  Since Rutschman ended up needing just a couple of days off and Maverick Handley is on hand as the backup catcher, Tromp will now head to DFA limbo after making two in-game appearances during his brief time on Baltimore’s roster.

Tromp has seen at least a little action in each of the last six MLB seasons, appearing in 63 total games with the Giants, Braves, and Orioles from 2020-25.  Tromp is out of minor league options, and thus the O’s had to designate him and expose him to the waiver wire before trying to send him down to Triple-A.  If Tromp clears waivers, he can reject an outright assignment to Triple-A because he has previously been outrighted in his career.  It remains to be seen if Tromp may choose to move on from the Orioles given the crowded depth chart of Rutschman, Handley, and Sanchez, as Tromp may prefer to join a team that has more of a clear path to big league playing time.
