Orioles To Sign Lou Trivino To Major League Deal
The Orioles have signed right-hander Lou Trivino to a major league deal, reports Ken Rosenthal of The Athletic. The Pro Edge Sports Management client just opted out of a minor league deal with the Phillies a few days ago. Baltimore has an open 40-man spot and doesn’t need to make a corresponding move in that regard. They will have to open an active roster spot.
Trivino, 34, signed a minor league deal with the Phillies in the offseason. The veteran finished the 2025 season on Philly’s big league roster and became an an Article XX(B) free agent, which essentially means he was a standard free agent, one who has at least six years of service time and wasn’t signed for the following season. When those players sign minor league deals, they come with automatic opt-outs five days before Opening Day, May 1st and June 1st.
The Phils didn’t break camp with Trivino on the roster but he skipped his first opt-out chance and reported to Triple-A Lehigh Valley. He put up excellent numbers for the IronPigs, giving them 13 innings with a 2.77 earned run average. His 35.7% strikeout rate, 7.1% walk rate and 50% ground ball rate were all above-average numbers. He triggered the second opt-out in his deal and the Phillies let him go.
The Orioles will take advantage and scoop Trivino up from the open market. Trivino’s recent Triple-A work is a small sample but the veteran also has a solid track record. In 332 1/3 big league innings, he has a 3.87 ERA, 23.5% strikeout rate, 10.4% walk rate and 45.3% ground ball rate. He has 37 saves and 57 holds in his career.
Injuries prevented him from appearing in the majors in 2023 or 2024. He was back in the bigs last year, though with slightly diminished results. His 3.97 ERA was fine but his 17.9% strikeout rate and 33.8% ground ball rate were both below league average and shy of his previous career numbers. His results so far in 2026, though in a small sample in the minor leagues, are an encouraging sign that he can get back to his previous form now that he’s further removed from his injury woes.
The Orioles have been hit hard by injuries this year, with 11 players currently on the injured list. That includes four relievers. They have known since last year that Félix Bautista would miss most or all of the 2026 campaign due to shoulder surgery. They signed Ryan Helsley to take over the closer’s job but now he’s on the IL with elbow inflammation. Yaramil Hiraldo and Colin Selby are also on the shelf.
It’s a fairly wide open bullpen mix. Hopefully, Trivino can provide a stabilizing veteran presence. If the O’s want to bump him off the roster in the future, he has enough service time where he can’t be optioned to the minors without his consent.

Astros Designate Daniel Johnson For Assignment
The Astros announced that outfielder Daniel Johnson has been designated for assignment. His roster spot goes to fellow outfielder Zach Cole, who has been recalled from Triple-A Sugar Land in a corresponding move. Chandler Rome of The Athletic was among those to pass along the news.
Johnson, 30, was added to Houston’s roster a couple of weeks ago amid a flurry of outfield injuries. Jake Meyers, Joey Loperfido and Taylor Trammell all hit the injured list in the middle of April, sapping the Astros of many of their best center field options. Cole was on the minor league injured list at the same time and wasn’t an option to help out.
Unfortunately, Johnson wasn’t much of a help. He got sent to the plate 17 times and produced a tepid .143/.294/.143 slash line. Brice Matthews, meanwhile, has largely taken over the center field job. Matthews’ .221/.289/.412 line isn’t amazing but it’s much better than what Johnson has been providing. Matthews has been receiving solid grades for his defense and speed as well. Now that Cole is healthy again, he’s been called up with Johnson bumped off.
Since Johnson is out of options, he had to be removed from the 40-man roster. He’ll be in DFA limbo for a week at most. The waiver process takes 48 hours so Astros could take five days to explore trade interest but they could also place him on waivers sooner if they so choose. He has been previously outrighted in his career and would therefore have the right to elect free agency if he is outrighted again. His speed and defense give him some appeal but a career batting line of .191/.249/.306 is obviously unattractive.
Cole was called up last year and flashed some fun upside, hitting four home runs in just 15 games. However, he also struck out in 38.5% of his plate appearances. He started this year on optional assignment and suffered a broken toe after just a few games. Now that he’s recovered and there are opportunities in the outfield, he will try to earn some playing time, ideally with fewer punchouts.

Brewers Designate Greg Jones For Assignment
The Brewers announced that both outfielder Jackson Chourio and first baseman Andrew Vaughn have been reinstated from the 10-day injured list. In corresponding moves, outfielder Blake Perkins has been optioned to Triple-A Nashville and infielder/outfielder Greg Jones has been designated for assignment.
The returns of Chourio and Vaughn should provide a sizable boost to a Brewers lineup that has relied heavily on complementary pieces in recent weeks. Milwaukee has a pair of 13-run outbursts in its past 11 games but has also been held to four or fewer runs seven times in that span. Much of the recent uptick in offense came against a D-backs staff that’s been struggling enormously over the past few weeks.
Chourio, 22, has missed the whole seasons thus far after suffering a fractured hand during exhibition play this spring. He went 1-for-9 with three walks in a brief three-game minor league rehab stint. The Brewers are hoping that the dynamic outfielder can recreate something close to — ideally better than — his career .272/.316/.463 slash (115 wRC+) with only minimal rehab work.
Similarly, Vaughn notched only one hit in three rehab games before his reinstatement. The former No. 3 overall pick enjoyed one of the most dramatic turnarounds in recent memory last year after going from Chicago to Milwaukee in a trade. Vaughn arrived in the Brewers organization with a career .248/.303/.407 batting line but erupted with a .308/.375/.493 batting line in 64 games down the stretch. He belted nine homers in 254 trips to the plate — then tacked on another two postseason taters in 30 plate appearances. Vaughn posted an outrageous .367/.436/.612 line in 55 spring plate appearances before incurring a hamate fracture that required surgery.
Jones went 2-for-21 in his brief time with the Brewers. He drew one walk, stole a base and struck out nine times in 22 plate appearances (40.9%). The 2019 first-rounder (Rays) only had 30 big league plate appearances to his credit. He’s spent parts of four seasons in Triple-A, where he’s a .262/.344/.438 hitter. Jones was drafted as a shortstop but has worked primarily as an outfielder in recent seasons. He has top-of-the-scale speed but marginal power and a bottom-of-the-scale hit tool that’s regularly produced strikeout rates north of 33% in Triple-A.
The Brewers will have five days to trade Jones, release him or place him on outright waivers. Outright waivers would be another 48-hour process, meaning Jones’ DFA will be resolved within a week’s time. He doesn’t have three years of major league service and has never cleared waivers before, so if he goes unclaimed this time around, he’ll be assigned outright to Nashville. He’d no longer count against the 40-man roster but would remain in the organization.
White Sox To Sign Randal Grichuk
The White Sox and outfielder Randal Grichuk are in agreement on a major league deal, reports Robert Murray of FanSided. The Sox will need to make corresponding moves to open space for the Paragon Sports International client on the active and 40-man rosters.
Grichuk elected free agency just three days ago after being designated for assignment by the Yankees. The 34-year-old had broken camp on a minor league contract to work in a short side platoon role. He was essentially the last man on Aaron Boone’s bench and took more than two-thirds of his 33 plate appearances versus lefty pitching.
Despite the favorable matchup deployments, Grichuk didn’t hit over his scattered playing time. He batted .194 without a home run while striking out 10 times. He worked one walk and had a .212 on-base mark. Grichuk didn’t perform especially well against left-handed pitching last season either, batting .227/.273/.430. He was among the best hitters in MLB against southpaws from 2022-24, however, destroying them at a .317/.367/.573 clip. He connected on 25 homers, 34 doubles and four triples in just under 500 trips against lefties over those three years.
Grichuk hasn’t played center field in three seasons and has been a well below-average hitter against righty pitching. It’s a limited profile but one the Sox feel comfortable carrying on their bench. They lost right fielder Everson Pereira to the injured list last week with a pectoral strain. Jarred Kelenic was selected onto the MLB roster in his stead and is out to a 1-6 start over three games. The lefty-hitting Kelenic and right-handed Austin Hays — a similar player to Grichuk — are dividing right field work.
The White Sox could create a 40-man roster spot for Grichuk by transferring Tanner Murray to the 60-day injured list. However, they may need to designate someone for assignment given their lack of active roster flexibility.
Backup catcher Drew Romo is the only player on Will Venable’s bench who has minor league options. They’re presumably not going to move on from Hays a month into a $6MM free agent deal. Andrew Benintendi isn’t performing but is signed through 2027 and remains the team’s leadoff man. Rookie left fielder Sam Antonacci is playing too well to option out.
Luisangel Acuña has been ice cold to begin the season, but he headlined Chicago’s return for Luis Robert Jr. over the offseason. They haven’t made the same investment in Kelenic, an offseason minor league signee, or September waiver claim Derek Hill. Hill has decent numbers this season but has struck out 14 times in 44 plate appearances and has only started 10 of the first 34 games.
Red Sox Select Alec Gamboa
The Red Sox announced they have selected the contract of left-hander Alec Gamboa from Triple-A Worcester. Chris Cotillo of MassLive.com first reported that Gamboa was on a flight to Detroit and likely to be added after exercising an upward mobility clause. He takes the active roster spot of fellow lefty Danny Coulombe, who has been placed on the 15-day injured list due to cervical spasms, retroactive to May 2nd. To open a 40-man spot, lefty Patrick Sandoval has been transferred to the 60-day IL.
Gamboa will take the mound as a 29-year-old rookie when he’s first plugged into a game. The 2019 Dodgers ninth-rounder spent years climbing the ranks in L.A.’s system but never reached the majors. The Dodgers granted him his release last year in order to sign with the KBO’s Lotte Giants, and Gamboa wound up making 19 starts with a 3.58 ERA in 108 innings in that overseas run. He fanned just under one quarter of his opponents, issued walks at a 10.3% clip and recorded a 55.2% ground-ball rate. Both his ERA and FIP were about 20% better than league average in South Korea’s hitter-friendly environment.
That showing prompted the Sox to bring Gamboa aboard on a minor league deal. He only pitched two spring innings and has tossed 13 frames in Worcester. The 6.23 ERA he’s turned in thus far isn’t going to generate much excitement, but Gamboa has a nice 25.4% strikeout rate with a solid 8.5% walk rate and a huge 57.9% grounder rate. He’s been plagued by a mammoth .405 average on balls in play that’s sure to regress closer to the .290 league average.
This move will keep the Sox with an even split in their bullpen for now. They have been operating with four lefties and four righties. Coming into today, the southpaws were Aroldis Chapman, Jovani Morán, Tyler Samaniego and Coulombe. It’s unclear how long Coulombe is expected to be out but Gamboa will slot in for him.
Presumably, Gamboa has a full slate of options, since this is his first major league call-up. Sometimes, a player coming to North America from overseas will get language in his contract stating that he can’t be sent to the minors without his consent, though it’s unlikely that a minor league contract would have such a provision. Samaniego has options if the Sox need a fresh arm at some point.
As for Sandoval, he still hasn’t pitched in the majors since June of 2024. He underwent surgery on his ulnar collateral ligament that month and has been in recovery mode ever since. The Angels non-tendered him at the end of that year, which led to the Sox signing him to a two-year deal worth $18.25MM.
Boston knew that they likely wouldn’t get much from Sandoval in 2025 but presumably hoped he would be back on the mound by now. He began a rehab assignment a few weeks ago but that was shut down after just two outings due to some biceps soreness.
His current timeline is unclear but this transaction rules out any chance of him returning in the next few weeks. His 60-day count is retroactive to his season-opening placement on the 15-day IL but that still means he’s ineligible for reinstatement until late May.
Boston’s rotation was supposed to be a strength but injuries have really impacted them. In addition to Sandoval, they have Garrett Crochet, Sonny Gray, Kutter Crawford, Johan Oviedo and Tanner Houck on the IL. Ranger Suárez hasn’t been placed on the IL but did depart his most recent start with a hamstring strain. For now, assuming Suárez avoids the IL, he is surrounded by Brayan Bello, Payton Tolle, Connelly Early and Jake Bennett in the rotation. Bello has a 9.12 ERA and would probably be in the minors if not for all these injuries. Unless he gets back on track soon, he could be in an awkward spot as guys come off the IL.

Marlins Recall Joe Mack For MLB Debut, Option Agustin Ramirez
May 4: Miami has formally announced both moves. Mack has been recalled from Jacksonville, and Ramirez has been optioned there in his place.
May 3: The Marlins will promote top catching prospect Joe Mack prior to tomorrow’s game with the Phillies, SportsGrid’s Craig Mish reports. Agustin Ramirez will be optioned to Triple-A in the corresponding 26-man roster move, and Mack is already on Miami’s 40-man roster.
Mack was the 31st overall pick of the 2021 draft, and after steadily working his way up the Marlins’ minor league ladder, the 23-year-old is now on the cusp of his Major League debut. Baseball America ranks Mack as the 50th-best prospect in the sport, and pundits like The Athletic’s Keith Law (52nd), MLB Pipeline (54th) and ESPN.com (61st) also have Mack listed within their top-100 rankings.
The consensus is that Mack is ready for the big leagues on defense alone, as he has received praise for his framing, blocking, and strong throwing arm. There have been fewer questions about his ability to hit since Mack bounced back from a poor 2023 season to post much better numbers across the last three minor league campaigns, and he has hit .249/.334/.444 with 21 home runs over 515 plate appearances with Triple-A Jacksonville.
Mack’s approach is a little all-or-nothing since he is primarily looking to pull the ball in the air, but even if this leads to his share of strikeouts, Mack has enough power to capitalize when he does make contact. Over 103 PA in Jacksonville this season, Mack’s walk rate has shot up to 19.4% (from 8.5% in 412 Triple-A PA in 2025) and he has reduced his strikeout rate from 27.9% to 21.4%.
It was seen as just a matter of time before Mack got the call to the Show, even if the Marlins opted against including Mack on their Opening Day roster. Miami continued with the catching tandem of Ramirez and Liam Hicks, and Hicks has broken out to hit .309/.366/.557 with seven homers over 112 PA while splitting time between catcher, first base, and DH.
Ramirez, however, is hitting .230/.318/.345 with two home runs over 129 PA, making him the odd man out of the catching picture. Ramirez went yard 21 times in 2025 while batting .231/.287/.413 in 585 PA, but his dropoff in power has taken away his most potent offensive weapon. Since Ramirez is also arguably the worst defensive catcher in baseball, there wasn’t much of a case to continue giving him at-bats while Mack was ready to go at Triple-A, as MLBTR’s Darragh McDonald argued earlier this week.
Since Hicks is also nothing special in terms of glovework, putting Mack behind the plate should have an immediate impact on the Marlins from a defensive standpoint. While obviously the hope is that Mack can adjust quickly as a big league hitter, producing even average offense in his first looks at MLB pitching would be a bonus along with the ripple effect that Mack’s defense brings to Miami’s run-prevention efforts.
Because Mack is only coming up to the majors now, the Marlins wouldn’t earn a bonus draft pick via the Prospect Promotion Incentive if he wins NL Rookie of the Year (or has a top-three MVP finish before he is eligible for arbitration). However, Mack himself would earn a full year of big league service time if he does manage a top-two ROY finish, and he is currently on pace to achieve Super Two status and an extra year of salary arbitration eligibility if he remains on Miami’s active roster.
Cionel Perez Elects Free Agency
May 4: Perez has rejected his outright assignment in favor of free agency, the Nationals announced Monday.
May 2: The Nationals announced that left-hander Cionel Perez has cleared waivers and been outrighted to Triple-A Rochester. Right-hander Orlando Ribalta was called up from Triple-A to take Perez’s spot on the 26-man roster, and Washington now has only 39 players on its 40-man roster.
There wasn’t any previous indication that Perez had been designated for assignment, and the lefty actually pitched just yesterday in the Nationals’ 6-1 loss to the Brewers. Perez tossed two scoreless innings in what could be his final game in a Nats uniform, and the transaction could’ve been made in part so Ribalta could provide a fresh arm for the bullpen. Since other relievers still have minor league options remaining, however, the Perez outright could indicate that the team has just decided to move on from the 30-year-old.
Signed to a minor league deal over the offseason, Perez made the Nats’ Opening Day roster and thus locked in a $1.9MM guaranteed salary. Things haven’t gone well, as Perez has recorded more walks (11) than strikeouts (nine) while posting a 6.19 ERA over 16 innings. Batters have been making tons of hard contact against Perez’s pitches, and the damage could be even worse if it wasn’t for Perez’s 60.4% grounder rate and a favorable .275 BABIP.
Perez has been outrighted in the past, so he has the right to decline the Nationals’ assignment to Rochester in favor of free agency. Perez’s month-plus on Washington’s roster has now given him enough big league service time to cross the five-year threshold, so he can now retain the approximately $1.5MM remaining of his $1.9MM salary even by becoming a free agent. If Perez signs elsewhere, his new team would pay him the prorated portion of the league minimum salary, which is subtracted from the $1.5MM sum that is still Washington’s responsibility.
Andrew Chafin Opts Out Of Reds Deal
Veteran lefty Andrew Chafin triggered an opt-out clause in his minor league contract with the Reds and is now a free agent, reports Jon Heyman of the New York Post.
The 35-year-old Chafin has already been with two teams this season. He spent most of spring training with the Twins but was granted his release after being informed he wouldn’t make their Opening Day roster. Chafin posted good bottom-line results with shaky rate stats both in camp with the Twins and in Triple-A with the Reds. He tossed six spring innings and allowed only two runs; he struck out 20% of his opponents but also walked 12% of them. It’s been a similar story in Louisville with the Reds’ top affiliate. Chafin has allowed only one earned run in 9 1/3 frames (0.96 ERA) with a nearly average 21.6% strikeout rate, but he’s walked 16.2% of his opponents.
During spring training, Chafin sat just 85.7 mph with his four-seamer and sinker alike. He’s added some life back to both pitches as he’s ramped up, evidenced by his 88 mph average four-seamer and 87.7 mph sinker with the Reds’ Louisville club. Both, of course, are still bottom-of-the-scale velocity marks in today’s game. Chafin posted a 2.41 ERA in 33 2/3 big league innings last year while averaging 89.5 mph on his four-seamer and 89.7 mph on his sinker. That was the first time since his brief 14-inning MLB debut in 2014 that he averaged less than 91 mph on either pitch, however.
While some clubs may express trepidation over his diminishing velocity, Chafin has never been a hard thrower and has still found consistent success in the majors. He’s averaged just 91.5 mph on his four-seamer and sinker dating back to 2021 and still has a 3.03 ERA in that time. He’s fanned 26.7% of his opponents against a 10.3% walk rate along the way, tacking on a slightly above-average 43.3% grounder rate for good measure. Chafin has picked up 17 saves and 71 holds in that time. Overall, he has a 3.35 earned run average, 20 saves and 153 holds in parts of 12 major league seasons between the D-backs, Cubs, A’s, Tigers, Brewers, Rangers, Nationals and Angels.
There’s no shortage of teams in the league currently in need of some help in the bullpen. The Twins may regret opting not to carry him on the roster after their bullpen has predictably been a disaster (5.31 ERA — 28th in MLB). The Astros have MLB’s worst bullpen by ERA (6.20). Chafin’s former Angels sit between that pair with a 5.62 ERA on the season. The Brewers have three lefty relievers on the injured list. The Cubs have five relievers on the IL at the moment. Chafin’s track record ought to earn him a look with another club before too long.
Nationals Sign Shawn Dubin To Minors Contract
The Nationals signed right-hander Shawn Dubin to a minor league contract, as reflected on the team’s official transactions page. Dubin made his debut with Triple-A Rochester yesterday, tossing a scoreless inning of relief work.
Dubin has a 4.81 ERA, 22.3% strikeout rate, and 10.2% walk rate over 88 career innings in the majors, all with the Astros and Orioles during the 2023-25 seasons. The righty had spent his whole career in the Astros organization before he was designated for assignment last August and then claimed by Baltimore. The O’s outrighted Dubin in November and he caught on with the Diamondbacks on a minors deal, but he was released from that contract 10 days ago after just two games with Triple-A Reno.
Washington has already used 22 different pitchers this season, so Dubin has a good chance of making it back to the majors as part of the Nats’ bullpen churn. Dubin is out of minor league options, however, so any call-up may well be followed by a DFA if the Nationals want to get another fresh reliever in the pen.
The Nats’ bullpen is unsettled enough that there’s opportunity for Dubin to stick around if his contract is selected. Dubin’s history as a swingman and long reliever makes him a candidate to eat innings, and he has shown good-to-great strikeout ability in the minors, even if he has yet to miss many bats during his time in the majors.
Yankees Option Anthony Volpe To Triple-A
The Yankees have activated Anthony Volpe from the 10-day injured list and optioned the shortstop to Triple-A, as per a team announcement. Joel Sherman of the New York Post broke the news shortly before the Yankees’ official release.
After undergoing shoulder surgery last October, Volpe began this season on the 10-day IL to allow more time to fully recuperate. He began a minor league rehab assignment in April that has thus far consisted of 13 games (nine in Double-A, four in Triple-A), and today marked the final day of the 20-day window allotted for rehab assignments. The Yankees therefore had to decide on activating Volpe and adding him either to the big league roster, or optioning him to Triple-A.
The writing seemed to be on the wall yesterday when New York manager Aaron Boone said Volpe would be kept in the minors for the entirety of his 20-day rehab period. While Boone said Volpe was in “a really good spot and had a good rehab,” the skipper also noted that the shortstop “played, what, two-plus weeks of games. Spring Training is a lot longer than that. And he got a lot of live at-bats and reads in the field even leading up to that. He’s had pretty much close to a full Spring Training, but I don’t think it hurts to have him continue to play regularly.”
This rehab assignment had marked Volpe’s first taste of minor league ball since 2022, as had pretty much been a fixture at the Yankees’ shortstop position since he made his MLB debut on Opening Day 2023. As a consensus top-10 prospect in baseball, Volpe’s debut came with a ton of hype, and those (probably unfair) expectations have yet to be met over three big league seasons.
Volpe has hit .222/.283/.379 with 52 homers over 1886 career PA in the Show, translating to an 85 wRC+. He was at least a superb defender in his first two seasons and won the AL shortstop Gold Glove in 2023, but Volpe’s glovework also drastically dropped off last year, likely due to the fact that he played through much of the season with a partially torn left labrum.
New York acquired Jose Caballero from the Rays at last summer’s deadline, and the utilityman quickly made an impression upon his arrival in the Bronx, particularly when he filled in at shortstop when Volpe spent a week recovering from a cortisone shot. With the knowledge that Volpe could likely miss time at the start of the 2026 campaign to recover, the Yankees explored the shortstop market last winter but opted to stick with Caballero as the interim shortstop, and the results have been very solid.
Through 124 PA this season, Caballero is hitting .259/.306/.405 with four home runs, as well as 13 stolen bases in 17 attempts. Even his modest 99 wRC+ is still an improvement over Volpe’s career numbers, and Caballero has also put himself in the early Gold Glove conversation with his strong defensive play at shortstop.
The “if it ain’t broke, don’t fix it” cliche may be the simplest answer behind the Yankees’ decision on Volpe. New York is 23-11 and its .676 winning percentage is the second-best in baseball, behind only the Braves. There isn’t any real pressing need for Volpe to be brought up now, and should Caballero start to struggle or if an injury arises elsewhere within New York’s infield, Volpe can easily be called up for his 2026 debut.
(In what may be a related item, Ben Rice is day-to-day with a left hand contusion that forced him out of today’s game. X-rays were negative on Rice’s hand, and the fact that the Yankees are still optioning Volpe is probably a sign that Rice might miss a game or two at most.)
In the bigger picture, it is fair to wonder if Volpe is still considered a key piece of the Yankees’ future plans. He is only in his first year of arbitration eligibility and is under team control through 2028, yet Volpe now finds himself in the position of seemingly having to just win his old job back, let alone figure out how to break out against MLB pitchers. New York has another top shortstop prospect in George Lombard Jr. knocking on the door for his big league debut, so Lombard might supplant Volpe if Caballero hasn’t done so already.
