Pirates Claim Ronny Simón, Designate Tanner Rainey For Assignment
2:25pm: The Pirates announced that they have claimed Simón and optioned him to Triple-A Indianapolis, with Rainey designated for assignment as the corresponding move.
1:25pm: The Pirates have claimed infielder Ronny Simón off waivers from the Marlins. The latter club designated him for assignment last week. Right-hander Tanner Rainey has been designated for assignment to open a 40-man roster spot for Simón. Mike Rodriguez first reported that Simón would be joining the Pirates. Craig Mish of the Miami Herald reported that it would be a waiver claim. Alex Stumpf of MLB.com reported that Rainey was the corresponding move.
Simón, 25, got his first major league call just over a month ago. The Marlins selected his contract on April 20th and he stuck on the roster until he was designated for assignment on May 30th. He got into 19 games and stepped to the plate 56 times, producing a batting line of .234/.327/.277.
That was a fairly unremarkable performance from a statistical point of view but Simón got thrust into the spotlight in an unusual way. As relayed Jason Foster and Christina De Nicola of MLB.com, Simón had a nightmare game against the Padres last week. The Fish were up 6-0 on Tuesday but several errors and general defensive miscues from Simón allowed the Friars to engineer an 8-6 comeback victory.
Amid the chaotic contest, Simón was seen wiping tears from his face. After the game, he received plenty of encouraging messages from his teammates and even his opponents. Per the MLB.com story, Padres such as Manny Machado, Luis Arráez and Fernando Tatis Jr. sent supportive texts to Simón after the game. In addition to that challenging on-field experience, Simón also had to deal with getting sent into DFA limbo a few days later. However, he has quickly found a new home by landing with the Pirates.
Simón’s major league time isn’t much to go on. Presumably, the Pirates are paying more attention to his minor league work. In 2,328 minor league plate appearances, he has a .266/.341/.446 line and 108 wRC+. Before getting called up this year, he got into 15 Triple-A contests and had a massive .354/.441/.521 line in that small sample.
As of July of last year, FanGraphs considered Simón to be one of the top 20 prospects in the Rays’ system, noting that his switch-hitting and defensive versatility gave him a good shot to eventually become a utility player. He has experience at the three infield positions to the left of first base as well as the outfield corners. He’s generally been able to steal about 20-35 bases annually. The Rays didn’t give him a 40-man spot at the end of last year, which led him to sign a minors deal with the Marlins coming into 2025.
He still has a full slate of options, so the Pirates can keep him in the minors if they don’t have room at the big league level. Rainey’s DFA does open an active roster spot but the Pirates might recall a pitcher rather than playing with the pitching staff shorthanded.
Rainey, 32, signed a minor league deal with the Pirates in the offseason and was selected to the roster about a month ago. He has since tossed 7 2/3 innings over 11 appearances, allowing nine earned runs. There’s surely a bit of luck in there, especially from a 35.7% strand rate that is ridiculously low, but he also hasn’t done himself any favors by walking 16.2% of batters faced. On the positive side, his 24.3% strikeout rate and 45% ground ball rate are solid numbers.
He’ll now head into DFA limbo, which can last for as long as a week. The waiver process takes 48 hours, so the Pirates could take five days to try to line up a trade. Rainey’s overall track record includes 197 big league innings with a 5.44 ERA. From 2019 to 2024, he logged 182 1/3 of those innings with a 4.49 ERA, 28.5% strikeout rate and 14.1% walk rate.

Marlins Outright Matt Mervis
Marlins first baseman Matt Mervis passed through waivers unclaimed following his recent DFA and has been assigned outright to Triple-A Jacksonville, reports Craig Mish of SportsGrid and the Miami Herald.
Mervis, 27, generated some buzz among Marlins fans when he homered six times in an eight-game stretch early in the season. Even during that blistering hot streak, however, he fanned in 39% of his plate appearances. The lefty-swinging slugger has always had good power but has never made contact in the majors. Mervis’ lack of hit tool and poor swing decisions caught up to him quickly after that power surge. From April 17 through his DFA in late May, he slashed .125/.213/.213 with a 36% strikeout rate and only one home run.
This is the third season in which Mervis has seen big league time. He’s tallied 261 plate appearances between the Cubs and Marlins but managed only a .165/.238/.322 batting line (53 wRC+) due in large part to a 34.5% strikeout rate. His 66.9% contact rate in that time ranks 470th out of 485 big leaguers (min. 250 plate appearances).
In parts of four Triple-A seasons, Mervis has fared far better. He’s a .269/.371/.511 hitter in 1045 plate appearances and, more encouragingly, has only fanned in 23.3% of his plate appearances there. He’ll spend time in Jacksonville continuing to work on his plate discipline and swing decisions. There’s little doubting Mervis’ power; he bashed 36 home runs in the minors back in 2022 and has connected on 73 round-trippers over his past 1369 plate appearances in the minors. Miami doesn’t have anyone firmly blocking him at first base, so if he can make some gains in Triple-A, another look could be in store for him later this season.
D-backs Release Joe Mantiply
The Diamondbacks released lefty Joe Mantiply after his recent DFA, per their transaction log at MLB.com. Assuming he clears release waivers, he’ll be a free agent who can sign with any team tomorrow afternoon.
Mantiply, 34, has been a frequent presence in Arizona’s bullpen dating back to 2021. From ’21-’24, he pitched 198 1/3 innings with a 3.63 ERA, a 22% strikeout rate, a 6.1% walk rate, a 51.9% grounder rate, 50 holds and three saves. In 2022, specifically, he was one of the team’s most frequently used relievers in high-leverage spots.
The 2025 season has been an abject disaster for Mantiply, however. He fired a perfect inning in his first appearance of the season and immediately tanked thereafter. By the time Arizona optioned Mantiply to Triple-A Reno on April 19, he’d been tagged for a calamitous 13 runs in just 7 1/3 innings across eight relief outings. He got another look in mid-May and was quickly optioned again after surrendering four runs in 2 1/3 innings.
Even Mantiply’s time in Triple-A was generally a struggle. He allowed four runs in his first appearance with Reno and five in his final one. Those ugly outings bookended a strong run of 9 2/3 shutout innings, but the overall results were grim. In 9 2/3 MLB frames this year, Mantiply has a 15.83 ERA. He’s posted a 5.56 mark in 11 1/3 Triple-A innings.
Mantiply has always been a soft-tosser, but his fastball has bottomed out in 2025, averaging a career-low 88.2 mph. He sat 91.3 mph with the pitch back in 2021-22, when he was at his best, and was at 89.5 mph last year. He’s still filling up the strike zone, but doing so with diminished stuff has yielded diminished returns.
By all accounts, Mantiply is healthy at the moment. Teams are always in need of left-handed bullpen help, and Mantiply has a generally solid track record in the majors, so he ought to get another chance to turn his season around with a new club before too long. He’ll almost certainly need to pitch his way back to the majors on a minor league deal, however. He’s being paid $1.7MM this year, and the D-backs will remain on the hook for the rest of that salary — minus the prorated minimum for any team he spends with another club’s big league roster.
Mariners To Acquire Joe Jacques
12:10pm: Ari Alexander of KPRC 2 reports that the Mariners are sending right-hander Will Klein to the Mariners for Jacques. Klein was just designated for assignment by the Mariners a few days ago. The Dodgers will need to open a 40-man roster spot for him.
Klein has just 7 1/3 innings of major league experience, which all came last year. He allowed nine earned runs in that time. This year, he’s been in Triple-A and has posted a 7.17 ERA at that level with a strong 30.5% strikeout rate but also a massive 18.1% walk rate. That’s generally been his recipe throughout his minor league career.
7:11am: In an early morning deal, Joel Sherman of the New York Post reports that the Mariners are acquiring southpaw Joe Jacques from the Dodgers. The return headed to Los Angeles is not yet known, though unlikely to be significant given Jacques’s status as a player on a minor league deal.
Jacques, 30, was a 33rd-round pick by the Pirates all the way back in 2018. He climbed the minor league ladder with Pittsburgh and ultimately reached Triple-A with them before posting a 3.12 ERA across three levels of the minors in his final season with the organization. It wouldn’t be until 2023 when he made his big league debut as a member of the Red Sox, for whom he pitched to a pedestrian 5.06 ERA in 26 2/3 innings of work. He generated an excellent 64.7% ground ball rate, but struck out only 16.4% of his opponents while walking 8.2%. Overall, Jacques profiled as a roughly average to slightly below average reliever based on his peripheral numbers, including a 4.53 FIP and a 4.12 SIERA.
Jacques remained on Boston’s 40-man roster throughout the 2023-24 offseason, but ultimately made just one appearance at the big league level in 2024 before he was designated for assignment and plucked off waivers by the Diamondbacks. He had a similar experience with Arizona, appearing in one game before he was eventually designated for assignment to make room on the roster for newly-acquired reliever A.J. Puk. Those two outings in the majors last year saw him surrender three runs on six hits and a walk across three innings of work while striking out two. Meanwhile, the lefty pitched to a 5.48 ERA in 42 2/3 innings of work at the Triple-A level.
It was a lackluster performance overall, but when Jacques reached minor league free agency he was quickly snapped up by the Dodgers on a minor league deal back in November. Jacques has struggled to a 6.04 ERA in 22 1/3 innings at Triple-A so far this year, although a 3.82 FIP and a .391 BABIP suggest there could be some bad luck baked into those numbers. Clearly, the Mariners saw enough in the underlying metrics to have interest in acquiring him. Yesterday was a day many players on minor league deals around the league had the opportunity to trigger opt outs and upward mobility clauses; if that came to play in this deal, it wouldn’t be a surprise to see Seattle add Jacques to the 40-man roster once the deal becomes official.
One possible reason for Seattle to have interest in Jacques is their dearth of left-handed pitching options. Gabe Speier is the only lefty on the Mariners’ pitching staff at the moment, and while he’s currently in the midst of a resurgent season that’s made him a legitimate high-leverage option he’s just one season removed from a 5.70 ERA in 29 appearances. Jhonathan Diaz and Tayler Saucedo are both in the minors on the 40-man roster, but Diaz has been used primarily as a starter this season while Saucedo has surrendered four runs in 3 2/3 big league innings this year. It’s a thin enough group to justify the addition of another arm to the mix, especially one like Jacques that has a minor league option remaining.
Mariners Outright Blake Hunt
Catcher Blake Hunt went unclaimed on waivers after being designated for assignment by the Mariners and has been assigned outright to Triple-A, per the team’s transaction log. He hasn’t been outrighted in the past and doesn’t have three years of big league service, so Hunt does not have the right to reject the assignment in favor of free agency. He’ll remain with the organization on a crowded catching depth chart.
Hunt, 26, has been traded four times but still never taken the field for a big league game. The Padres selected him with the 69th overall pick back in 2017 and traded him to the Rays in the Blake Snell blockbuster. Hunt was with the Rays through 2023 before being traded to the Mariners in exchange for fellow minor league catcher Tatem Levins. Six months later, Hunt was on his way to the Orioles in exchange for reliever Mike Baumann, and after being designated for assignment in Baltimore later last year, he was shipped back to the M’s for cash.
Hunt is a glove-first catcher who draws strong marks for his minor league framing and blocking skills, in particular, per Baseball Prospectus. He’s long been touted for above-average to plus raw power but been dinged for a hit tool and an approach (or lack thereof) that don’t allow him to tap into that power often enough. He’s a career .232/.284/.413 hitter in parts of three Triple-A seasons, including a .231/.271/.407 slash this season that’s right in line with those career marks.
Seattle, of course, has the top catcher in all of baseball right now in switch-hitting slugger Cal Raleigh. Veteran Mitch Garver is backing Raleigh up and at least reaching base at a respectable .321 clip, but he’s hitting .204 with nowhere near the power he once displayed. Hunt is one of several catching options in the upper minors for the Mariners, who also have journeymen Jacob Nottingham and top prospect Harry Ford on their Tacoma roster.
Ben Rortvedt Accepts Outright Assignment With Rays
Catcher Ben Rortvedt, who was designated for assignment by the Rays last week, has cleared waivers and been sent outright to Triple-A Durham. He had the right to elect free agency but has chosen to accept. Marc Topkin of the Tampa Bay Times was among those to relay the information.
Players with at least three years of big league service time have the right to reject an outright assignment and elect free agency. However, exercising that right means forfeiting any remaining salary commitments, unless a player has at least five years of service time.
Rortvedt is between three and four years. He qualified for arbitration for the first time after last season. He and the Rays avoided arbitration by agreeing to a $1.125MM salary for 2025. Rortvedt has pocketed about a third of that already but would have to walk away from the rest of it in order to head to the open market, so it’s not surprising that he has chosen to report to Durham.
For the Rays, they get to keep a bit of experienced non-roster depth behind the plate. Rortvedt had a solid season for them in 2024, getting into 112 games and stepping to the plate 328 times. His .228/.317/.303 slash line wasn’t tremendous, as his 87 wRC+ indicates he was about 13% below league average at the plate. However, catches are usually about 10% below league-wide par, so Rortvedt’s offense was passable enough.
He also received solid marks for his work behind the plate. Putting the two together, FanGraphs considered him to be worth 1.4 wins above the replacement on the year, with Baseball Reference putting him a bit lower at 0.9 WAR.
The Rays were satisfied enough to give him a raise and bring him back for 2025 but his bat has disappeared. Rortvedt slashed .095/.186/.111 in 70 plate appearances before getting designated for assignment last week. A tiny .122 batting average on balls in play wasn’t helping him out but his batted ball metrics all trended in the wrong direction as well. The Rays signed Danny Jansen in the offseason and then acquired Matt Thaiss last week, pushing Rortvedt down the depth chart. Since Rortvedt is out of options, he got pushed off the 40-man entirely.
Though he’s not having a strong season, he should get some regular playing time for Durham and could perhaps get his offense back on track. If he’s able to do so, he could be the first man up if either Jansen or Thaiss suffers an injury. Logan Driscoll is also on the 40-man roster but he started the year on the minor league injured list due to an ankle injury and still hasn’t played an official game this year.
If Rortvedt isn’t called up by the end of the season, he will be able to elect free agency, as is the case with all players with three-plus years of service who are outrighted off a 40-man roster during the season.

Royals Promote Jac Caglianone
June 2: The Royals formally announced that Caglianone’s contract has been selected from Triple-A Omaha. Their 40-man roster is now full. Outfielder Dairon Blanco was optioned to Omaha to clear a space on the active roster. Kansas City is off today, so Caglianone’s debut will come tomorrow in St. Louis against Cardinals righty Andre Pallante.
June 1: One of baseball’s top hitting prospects is headed to the majors, as ESPN’s Jeff Passan reports that the Royals are calling up Jac Caglianone. The Royals have an off-day on Monday, which lines Caglianone up for his big league debut on Tuesday when the Royals start a series in St. Louis against the Cardinals. There are only 39 players on Kansas City’s 40-man roster, so the club can select Caglianone’s contract on Tuesday and then make just one corresponding transaction to create space on the active roster.
It was less than a year ago that Caglianone was still awaiting his draft call, as the University of Florida product was selected just in the 2024 draft when Kansas City took him sixth overall. Caglianone joins Cam Smith and Nick Kurtz as 2024 first-rounders that have already made their way to the Show, and Caglianone has (as you might expect) forced the issue by obliterating minor league pitching. While he had only a .690 OPS in 126 plate appearances at high-A ball in 2024, Caglianone has a combined .323/.391/.600 slash line in 225 combined PA at the Double-A and Triple-A levels this year.
Caglianone just played in his 12th Triple-A game today, so as dominant as the 22-year-old slugger has been, a case can be made that the Royals are being hasty in bringing him up to the majors this early in his pro career. That said, as MLBTR’s Steve Adams noted just a few days ago, K.C. might’ve felt a bit of added motivation due to how little the team has gotten from its lineup, particularly in the outfield.

The seeds for Caglianone’s quick promotion were planted when he made his first appearance as an outfielder with Double-A NW Arkansas back in late April. Both a star first baseman and pitcher during his college days, Caglianone gave up on pitching to solely focus on hitting as a professional, and he has received a regular dose (though not an exclusive position change) of right field work over the last five weeks of minor league action.
With Vinnie Pasquantino playing first base in K.C. and several players getting cycled through the DH spot, putting Caglianone into right field is a logical way on paper for the Royals to both get a star prospect to the majors, and to help solve their longstanding need for outfield help. Even as the Royals reached the playoffs in 2024, their entire outfield was a major weak link, and Kansas City’s attempts to upgrade the position over the offseason just didn’t really pan out. Caglianone’s promotion is the latest step in a shake-up that has already seen MJ Melendez optioned to Triple-A in April, and Hunter Renfroe released earlier this week.
The left-handed hitting Caglianone figures to split time between right field, first base, and probably DH on occasion. Drew Waters and Kyle Isbel will continue to platoon in center field, while Mark Canha, Michael Massey, and Jonathan India will likely share left field duties, with Massey/India also playing at second base and Canha likely getting some time in right field spelling Caglianone against some southpaws. Broadly speaking, manager Matt Quatraro could be creative with his lineup given how Bobby Witt Jr. and Maikel Garcia are the only regulars with above-average production, and even Witt’s 121 wRC+ is a sizeable step back from his MVP runner-up season in 2024.
It makes for a pressurized situation for Caglianone in his first taste of MLB action, as K.C. fans have, if anything, felt Caglianone was overdue for a promotion. Royals GM J.J. Picollo spoke of the situation to Passan earlier this week, saying “The hardest part about this for us is we’re trying to do what’s best for the player. That’s ultimately what this is. You want the player to be as prepared as he can when he comes in the major leagues. It’s not fair to any player, whether it’s Jac Caglianone or whoever, when a team may be scuffling offensively, to try to put it on him and hope he’s going to come save the day.”
Caglianone’s minor league numbers indicate that he is ready for a step up in competition. MLB Pipeline ranked him as the 22nd-best prospect in baseball prior to the season, ESPN had him 29th, and The Athletic’s Keith Law (60th) and Baseball America (63rd) also had the slugger deeper in their rankings. The pundits agree that Caglianone is a gifted hitter with huge power and exit-velocity numbers, but the only question is whether or not there’s too much swing-and-miss in his game to handle big league pitching. Caglianone has done well in posting respectable strikeout rates in the minors this year though his chase rate is still ungainly.
Due to his inclusion in the top-100 lists, Caglianone qualifies as a Prospect Promotion Incentive player. This means that if he finishes in the top two in AL Rookie of the Year voting, he’d earn a full year of service time despite not being called up until June. The timing of Caglianone’s call-up means that if he stays in the majors for the remainder of 2025, he’d be on pace to earn Super Two status and an extra year of arbitration eligibility down the road.

Dodgers Place Luis Garcia On 15-Day Injured List
The Dodgers have placed right-hander Luis Garcia on the 15-day injured list due to a right adductor strain. The placement is retroactive to May 29. Righty Noah Davis was called up from Triple-A in the corresponding move.
Now in his 13th Major League season, Garcia has a 4.50 ERA in 26 innings for Los Angeles, along with a below-average 19.8% strikeout rate and an ungainly 12.9% walk rate. Garcia’s 4.13 SIERA is a bit more favorable since the groundball specialist has been hampered by a .364 BABIP, but he is also allowing a lot of hard contact.
Garcia signed a minor league contract with L.A. in February and locked in $1.5MM in guaranteed salary when that contract was selected in advance of the Dodgers’ early Opening Day in Tokyo. While his results have been up and down over his lengthy career, Garcia has generally been pretty durable, which probably helped his bid to make the team given the injury woes that have only worsened for the Dodgers’ pitching staff as the season has developed.
Incredibly, Garcia is the 15th pitcher currently on the team’s injured list. (That number could be viewed as 16, if you consider that Shohei Ohtani is still going through his pitching rehab.) Some help may be coming soon, as manager Dave Roberts told MLB.com’s Sonja Chen and other media today that relievers Michael Kopech and Kirby Yates could both be activated within the next week.
Getting those two quality bullpen arms back is a nice boost for the team, but needless to say, pitching health is once again a major subplot of the Dodgers’ season. While the elite L.A. offense has carried the Dodgers back to first place in the NL West, pitching figures to be a deadline need for Los Angeles regardless of how many hurlers have returned from the IL by July 31.
Dominic Smith Opts Out Of Minor League Deal With Yankees
Dominic Smith has become a free agent after triggering the opt-out clause in his minor league deal with the Yankees, ESPN’s Jeff Passan reports. Smith wasn’t an Article XX(b) free agent with a built-in June 1 opt-out date in any minor league contract, but his deal still apparently contained some opt-out flexibility if he hadn’t been called up to New York’s active roster.
This is the second time in three months that Smith has opted out of a minors deal with the Yankees, as he also opted out of his initial contract near the end of Spring Training but re-signed with the club just after Opening Day. Smith has since been playing at Triple-A Scranton/Wilkes-Barre, hitting .255/.333/.448 with eight home runs over 189 plate appearances. Smith has primarily been a left fielder, with a good chunk of playing time at first base and DH and a handful of games in right field.
Despite his decent numbers and his defensive flexibility, it isn’t hard to understand why the Yankees haven’t felt the need to bring Smith to the majors. Even with Giancarlo Stanton missing the entire season to date, Ben Rice capably stepped into the regular DH role, and Paul Goldschmidt has been excellent at first base. The outfield picture is also crowded between Aaron Judge, Cody Bellinger, Jasson Dominguez, and Trent Grisham surging into more playing time than expected due to some unexpectedly big production at the plate. With Stanton slowly working his way back to good health, the situation will only get more crowded in the Bronx barring future injuries, so another new contract might not be in the cards for Smith if he wants a clearer path to Major League playing time.
A former top prospect and near-breakout star during his time with the Mets from 2017-22, Smith’s production has tailed off and he has become something of a journeyman since leaving Queens. Smith has been a part of six different organizations since January 2023, and has hit .247/.321/.370 over 893 PA with the Nationals, Red Sox, and Reds.
Blue Jays Place Daulton Varsho On 10-Day IL, Activate Erik Swanson
Prior to today’s 8-4 win over the Athletics, the Blue Jays placed center fielder Daulton Varsho on the 10-day injured list and activated right-hander Erik Swanson from the 60-day IL to make his season debut. Left-hander Easton Lucas was optioned to Triple-A and second baseman/outfielder Davis Schneider was called up in the corresponding moves.
Varsho is dealing with a left hamstring strain suffered in Saturday’s game, as he came up limping while rounding second base in an attempt to stretch a double into a triple. Varsho was immediately removed from the game and an IL placement seemed inevitable, though manager John Schneider told MLB.com’s Keegan Matheson and other reporters today that Varsho sustained a relatively less-serious Grade 1 strain.
This still means Varsho will miss at least a couple of weeks of action, and it puts him back on the IL for the second time this season. Varsho had surgery last September on his right rotator cuff, and spent the first month of the 2025 campaign finishing off his injury rehab and getting his throwing arm back in game-ready shape. Since making his season debut on April 29, Varsho is hitting .207/.240/.543 with eight home runs over an even 100 plate appearances, displaying his usual recipe of power but not much in the way of average, OBP, or steady contact (Varsho has struck out in 31 of those 100 PA).
Beyond the numbers at the plate, Varsho has also displayed his customary stellar glovework in center field. The Jays have another quality defender in Myles Straw who can fill in while Varsho is out, and as Matheson notes, the club will probably re-deploy the Straw/Nathan Lukes platoon used in center field during Varsho’s first IL stint. George Springer, Alan Roden, or Jonatan Clase could also rotate into center field in a pinch, though Schneider said Springer had a minor ankle tweak in today’s game.
While it doesn’t appear as though Springer’s ankle issue is too serious, Toronto can hardly afford another outfield injury with Varsho and Anthony Santander already sidelined. Given the thin outfield, Davis Schneider is likely to primarily be used in left field during his latest stint in the majors. Second baseman Andres Gimenez is also expected back from his own IL stint in a few days’ time, and the resulting shuffle in the infield could see the hot-hitting Addison Barger moved into corner outfield duty.
Turning to the mound, Swanson ended up as the winning pitcher today, despite looking a little shaky (1 ER on a wild pitch, and a hit batter) in his lone inning of work. A median nerve entrapment sidelined Swanson during Spring Training, and he ended up being moved to the 60-day IL in early May when some forearm soreness delayed the start of a planned minor league rehab assignment.
Overall, Swanson has been quite solid in his two-plus seasons in Toronto, as he was outstanding in 2023 and then recaptured that form in the second half of the 2024 campaign. However, the first half of 2024 was marred by injuries, as well as some off-the-field trauma when Swanson’s four-year-old son was hospitalized after being hit by a car in February of that year. (Fortunately, young Toby was released from hospital within two weeks.)
