Austin Slater Elects Free Agency
Outfielder Austin Slater has elected free agency, according to his transactions tracker at MLB.com. The Mets had sent him outright to Triple-A Syracuse a few days ago but he has exercised his right to reject that assignment and head to the open market instead.
If a player has at least five years of big league service time, he has the right to reject an outright assignment while also keeping his salary commitments in tact. The Marlins signed Slater in late March, after the Tigers had granted him his release from a minor league contract. The Miami deal was a major league pact with a $1MM salary. The Fish cut bait less than a month into the season, designating Slater for assignment. He cleared waivers and elected free agency.
The Fish remain on the hook for the remainder of that salary. Other teams can sign Slater and only pay him the prorated portion of the league minimum, with that amount subtracted from what the Marlins pay. The Mets stepped up to volunteer for that opportunity but they also bumped Slater off their roster after less than a month. Between the two clubs, he has a rough .209/.286/.233 line on the year.
Other clubs may still be interested in him based on his track record. Slater has a decent floor from his speed and defense. In over 3,000 outfield innings in his big league career, spread across all three spots on the grass, he’s been credited with six Outs Above Average. On the whole, Defensive Runs Saved has him just a hair below average, but mostly due to that metric considering him subpar in center. He has five DRS in right field and four in left, with over 1,000 innings in each corner. Though he’s now 33 years old, Statcast still pegs his sprint speed in the 66th percentile of qualified big leaguers this year.
Offensively, Slater has been around league average in his career, but with caveats. A right-handed bat, he has done most of his damage against lefties. He has a .263/.352/.420 line and 115 wRC+ with the platoon advantage in his career but a .228/.313/.331 line and 81 wRC+ in the other half of the split. He has also seen his overall production decline lately. From 2020 to 2023, he slashed .259/.352/.421 for a 117 wRC+, regardless of pitcher handedness. Since then, he has a .212/.298/.304 line and 74 wRC+.
Despite the declining numbers, there is some lingering interest. The Yankees liked him enough to trade for him at last year’s deadline. He had to settle for a minor league deal in the winter but looked good in spring, hitting .267/.389/.467, and quickly got himself a big league pact. He hasn’t been able to carry that over into the season but his résumé should still be enough to at least get him a minor league deal somewhere, if not a major league one.

White Sox Designate Jarred Kelenic For Assignment
The White Sox announced that outfielder Jarred Kelenic has been designated for assignment. That’s the corresponding move for them to select infielder/outfielder Rikuu Nishida, a move that was reported yesterday.
Kelenic, 26, signed a minor league deal with the Sox in the offseason. He began the season at Triple-A and put up some encouraging numbers. In 26 games, he slashed .202/.346/.464. That batting average is obviously not pleasant but was held back by an unfortunate .224 batting average on balls in play. The on-base percentage was buoyed by a huge 18.3% walk rate. His six home runs in 104 plate appearances boosted the slugging percentage. The batting line translated to a subpar 97 wRC+ but would have been above average with a bit more batted ball luck.
The White Sox decided to give him another shot in the big leagues, which didn’t work out. He got into 19 games and stepped to the plate 59 times. His 10.2% walk rate was strong but he also struck out at a huge 33.9% clip. Though his .344 BABIP was actually a help in this sample, he nonetheless put up a .226/.305/.321 line and 81 wRC+.
These are fairly small data sets but they do roughly mirror Kelenic’s larger career arc. A former sixth overall pick and top prospect, he has often put up huge numbers in the minors without finding success in the majors. Including this year’s stint with the Sox, he now has 1,547 big league plate appearances. He has been punched out in 30.7% of those and has a .211/.283/.374 line, which leads to an 84 wRC+. He has stolen some bases but hasn’t received strong grades for his glovework.
The overall performance has pushed him into fringe roster status. As mentioned, he had to settle for a minor league deal coming into this season. He has exhausted his option years, so the Sox had to bump him off the 40-man since they no longer want him on the active roster.
Kelenic is now in DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Sox could take five days to explore trade interest. The most likely outcome is Kelenic ending up on waivers and clearing. He just cleared waivers in October of last year and he hasn’t done much to raise his stock since then. Players with a previous career outright or three years of service time have the right to reject outright assignments in favor of electing free agency. Kelenic qualifies on both counts and can head to the open market if he clears waivers in the next week.

The Opener: Dodgers’ Bullpen, Mariners’ Rotation, Detmers
Athletics first baseman Nick Kurtz extended his single-season on-base streak to 47 games with a third-inning single on Sunday. He’s now tied for second in franchise history. Kurtz can tie Mark McGwire for the A’s record tonight against the Mariners.
1. Dodgers relievers continue scoreless streak
The L.A. bullpen only had to cover two innings on Sunday with Yoshinobu Yamamoto tossing seven frames. Will Klein and Tanner Scott got the job done, combining for two perfect innings with four strikeouts. The Dodgers’ relievers have now delivered 38 consecutive scoreless innings, a franchise record in the modern era. It’s the longest leaguewide streak since Cleveland’s bullpen posted zeroes for 38 2/3 innings in 2017 (h/t Sarah Langs of MLB.com). The Dodgers’ bullpen has done it without star closer Edwin Diaz, who underwent elbow surgery in April.
2. Mariners swap piggyback roles on Monday
Mariners right-handers Bryce Miller and Luis Castillo tag-teamed in their last appearance. Miller covered the first 5 2/3 innings, then Castillo went 2 1/3 innings in relief. The starters got some help from relievers Jose A. Ferrer and Andres Munoz along the way. Seattle is flipping the order on Monday against the A’s. It’ll be Castillo making the start with Miller coming in relief, per Ryan Divish of the Seattle Times. It’s an interesting choice considering Miller’s strong work this season. The righty has allowed just two earned runs over 11 frames since returning from an oblique injury. Castillo has an ERA well above 6.00.
3. Detmers dominates Rangers
Angels left-hander Reid Detmers racked up 14 strikeouts on Sunday against Texas. He allowed just one hit over eight innings, a solo homer by Jake Burger. It was a much-needed outing after Detmers was tagged for eight earned runs in his last start. The lefty’s return to the rotation has had some bumps, but he’s pitched better than his 4.57 ERA. Detmers has a 2.87 xERA. His xFIP and SIERA are below 3.50. He’s been unlucky with a 59.4% strand rate. That number is 69.1% for his career. If Detmers can emerge as a reliable rotation option, he’ll provide a nice 1-2 punch with Jose Soriano. He could also be an attractive trade piece.

Padres Interested In Antonio Senzatela
The Padres are known to be looking to bolster what is already a strong relief corps, and USA Today’s Bob Nightengale writes that Rockies right-hander Antonio Senzatela is one of the names on San Diego’s radar. Nightengale also mentions Aroldis Chapman as a Padres target, echoing Dennis Lin of the Athletic’s report from a few days ago about the Padres’ long-standing interest in Chapman.
Senzatela is in the last guaranteed year of a five-year, $50MM extension he signed with Colorado back in October 2021, as the Rockies hold a $14MM club option (with no buyout) on his services for 2027. In this sense Senzatela is basically a rental player for any interested trade suitors, as that club option is unlikely to be exercised regardless of how well the righty pitches over the rest of the 2026 campaign.
Since signing that extension, Senzatela has tossed only 274 1/3 big league innings, as a torn ACL and a Tommy John surgery led to two extended stints on the injured list. Finally fully healthy heading into the 2025 season, Senzatela struggled to a 7.42 ERA over 108 innings and 23 starts before the Rockies moved him to the bullpen in August. The role switch seemed to work immediately, as Senzatela then delivered a 2.86 ERA over his first 22 innings as a reliever.
The improvement has carried over to some extent in 2026, though Senzatela’s sparkling 1.13 ERA carries several red flags. A .195 BABIP is probably the biggest reason why Senzatela’s 3.48 SIERA more than triples his real-world ERA. It isn’t just good luck, however, as Senzatela’s 6.8% walk rate is quite solid and his hard-contact numbers are vastly improved from his career norms. His 22% strikeout is a bit below league average, but also markedly better than the 14.7K% Senzatela posted over his first nine MLB seasons.
As one might expect, Senzatela’s move to relief pitching has bumped his velocity — after averaging 94.2mph on his fastball prior to 2026, Senzatela is now up to 97.1mph. Moreso than just the velo, Senzatela’s decreased usage of his four-seamer has made the pitch much more effective, as Senzatela has now introduced a cutter to his arsenal. The four-seamer has been thrown 35.2% of the time while the cutter isn’t far behind at 30.8%, and Statcast’s Run Value metric gives the cutter an impressive +6.
These results bode well for Senzatela’s chances of landing a decent contract when he hits free agency this winter, as it looks like the move to the pen has resurrected his career. In the shorter term, it makes him an obvious trade chip on a rebuilding Rockies team that is tied with the Angels for the worst record in baseball (20-34). Barring injury, Colorado will surely be moving Senzatela in advance of the trade deadline.
The wrinkle in regards to the Padres is that San Diego is apparently looking to make a move sooner rather than later. San Diego relievers have already logged 213 2/3 innings, the seventh-highest total of any relief corps in baseball. Though this heavy workload hasn’t stopped the Friars’ bullpen from being one of the best in the game, the front office is looking to be proactive in adding a relief arm or two to help keep everyone fresh for what the Padres hope is an even deeper playoff run.
On the flip side, the fact that the Padres’ desire for bullpen help is more of a want than a true need, they may not be operating with much desperation. That reduces what leverage the Rockies may have as one of the few teams in pure seller mode. While the Rox will definitely be selling and the Padres will (barring a total collapse in the next two months) definitely be buying, most prominent trades don’t take place until much closer to the deadline since clubs usually want to take their time in accessing their needs and gauging the market.
Since the Rockies’ priority should be on amassing talent rather than cutting payroll, Colorado could offer to eat virtually everything remaining on Senzatela’s contract (roughly $8MM of a $12MM 2026 salary) in order to maximize the prospect return. Such an offer could be of particular interest to the Padres, who project to be luxury tax-payors for the second straight season and didn’t spend much this past winter. Of course, the incoming new ownership group led by Jose E. Feliciano and Kwanza Jones could be willing to stretch the budget in pursuit of the franchise’s elusive first World Series ring.
It is perhaps worth noting that the Padres and Rockies are very infrequent trade partners who haven’t completed a non-cash considerations type of trade since December 2011. This may have less to do with a division rivalry than the fact that the Rockies generally made less trades as an organization than most other clubs, though president of baseball operations Paul DePodesta has already swung several lower-level deals in less than a year on the job.
IL Transactions: DeLuca, Winn, Coulombe, Baddoo
Here’s the round-up of some players departing and joining the injured list on Sunday…
- The Rays placed outfielder Jonny DeLuca on the 10-day injured list (retroactive to May 23) due to a right hamstring strain, and called up Victor Mesa Jr. from Triple-A Jacksonville. DeLuca suffered the injury while running the bases in Friday’s 4-2 Rays victory over the Yankees, and he underwent an MRI today to determine the severity of the strain. DeLuca has hit .269/.298/.412 over 125 plate appearances while chipping in at all three outfield positions, though most of his work has come as the right-handed hitting side of a right field platoon with Jake Fraley. Both sides of that platoon are now on the IL since Fraley is recovering from sports hernia surgery, leaving Ryan Vilade, Richie Palacios, and Mesa as the top candidates to pick up the slack in the outfield.
- The Rangers placed right-hander Cole Winn on the 15-day IL due to fatigue in his throwing arm, and called up right-hander Gavin Collyer (this was the only corresponding move since Collyer was already on the 40-man roster). Winn has a 25.8% strikeout rate and 7.9% walk rate over 19 1/3 innings out of the Texas bullpen, but a lot of hard contact and an unfavorable .345 BABIP have resulted in a 5.59 ERA that is far higher than his 3.25 SIERA. While Winn’s arm issue doesn’t seem too serious, he missed significant time in both the 2024 and 2025 seasons due to shoulder and rotator cuff problems.
- The Red Sox activated Danny Coulombe from the 15-day IL prior to today’s game with the Twins, and the left-hander tossed a scoreless inning of relief in Boston’s 6-5 loss. (Left-hander Tyler Samaniego was optioned to Triple-A in the corresponding move.) Coulombe missed a little over three weeks due to back spasms, and his 5.00 ERA over nine innings this season can be largely attributed to one very rough outing against the Yankees on April 23. Beyond that bad game, the southpaw has only allowed two runs over his other 8 1/3 frames of work.
- The Brewers announced that outfielder Akil Baddoo was activated from the 60-day injured list and optioned to Triple-A Nashville. After signing a split contract with Milwaukee during the winter, Baddoo suffered a quad strain near the end of Spring Training and has spent the entire season on the 60-day IL. The outfielder has logged some rehab games in Nashville already and will continue to bide his time until a possible call-up to the Show.
Orioles Designate Albert Suarez For Assignment
The Orioles announced that right-hander Albert Suarez has been designated for assignment. Prior to today’s doubleheader with the Tigers, Baltimore activated left-hander Grant Wolfram from the 15-day IL to use him as the 27th man, and Wolfram will now stay on the 26-man roster in Suarez’s place.
These transactions are becoming routine for Suarez, who has now been DFA’ed three times by the Orioles in under a month. The first designation saw Suarez clear waivers and then elect free agency, as a previous outright on his resume allowed him to decline the Orioles’ outright assignment to Triple-A Norfolk. However, Suarez quickly re-signed with the O’s on a minor league contract, then was selected back to the active roster, and DFA’ed and outrighted again within the span of five days.
This time, Suarez chose to just accept the outright assignment, and spent a couple of weeks in Norfolk before the Orioles selected his contract again last Tuesday. Unless Suarez is claimed off waivers, it seems probable that Suarez will end up staying with the O’s in some fashion, either via accepting the outright assignment or another free agent trip that results in another fresh minor league deal.
Suarez is out of minor league options, so the O’s have to designate him and expose him to the waiver wire whenever the club wants to shift him off the active roster. Suarez has some leverage in this back-and-forth situation given his ability to reject outright assignments, but it could be that he is content to stick it out in a familiar environment with the knowledge that he’ll probably get another look in the majors pretty soon.
Amidst all this roster shuffling, Suarez has a 2.75 ERA over 19 2/3 big league innings this season, including four shutout frames in Game 2 of today’s doubleheader (a 4-1 Orioles loss). Suarez’s ability to eat innings has made the former swingman and starter into a useful long man for Baltimore, though he has barely more strikeouts (10) than walks (nine) and he benefited greatly from a minuscule .186 BABIP.
Blue Jays’ Vladimir Guerrero Jr., Dylan Cease Leave With Injuries
8:35PM: Guerrero told Sportsnet’s Shi Davidi and other reporters postgame that he felt some numbness in his arm after being hit, but he described his status as just day-to-day. Manager John Schneider didn’t rule out Guerrero being in the lineup as early as Monday’s game with the Marlins, depending on how the All-Star feels after a night’s rest. Cease will undergo an MRI but also suggested to Schneider that he might not miss his next start, as the skipper said “all the [early] testing and stuff seemed pretty positive.”
1:51PM: The fifth inning on Sunday against the Pirates was a double whammy for the Blue Jays. Dylan Cease departed in the top of the frame with a leg injury. Vladimir Guerrero Jr. took a Mitch Keller sinker to the elbow in the bottom of the inning and was immediately replaced.
The team announced left hamstring discomfort as the reason for Cease’s removal. Guerrero has been diagnosed with a right elbow contusion. The first baseman had X-rays taken, which came back negative for a fracture, per the club.
Toronto has been among the most injured squads in the league. Catcher Alejandro Kirk, outfielder Nathan Lukes, and infielder/outfielder Addison Barger are currently on the injured list. Outfielder Anthony Santander had shoulder surgery will miss most or all of the season. On the pitching side, Jose Berrios, Bowden Francis, and Cody Ponce are done for the year. Shane Bieber has yet to appear this season. Max Scherzer remains out.
Cease is well-known for his impressive durability. The right-hander has never been on the 15-day injured list since debuting with the White Sox in 2019, apart from a brief stint in early 2021 for COVID-19 reasons. Cease has made 32+ starts in every season since the shortened 2020 campaign.
Guerrero also has a clean injury history. He’s never been on the injured list in his eight years in the big leagues. Guerrero has topped 155 games and 675 plate appearances in five consecutive seasons. An absence for either Cease or Guerrero would be challenging for Toronto to navigate, but neither injury seems like a major issue.

White Sox To Select Rikuu Nishida
The White Sox will select the contract of second baseman/outfielder Rikuu Nishida from Triple-A Charlotte prior to Monday’s game with the Twins, according to Ian Eskridge of FutureSox. Nishida isn’t on Chicago’s 40-man roster, so corresponding 26-man and 40-man moves will need to be made before the 25-year-old is officially selected.
Nishida will be making his Major League debut whenever he appears in a game. The 25-year-old Osaka native arrives in the Show without the NPB background of most Japanese players, but he played college ball at Oregon and was an 11th-round draft pick for the White Sox in 2023.
With two more hits today for Charlotte, Nishida is now hitting a blistering .347/.454/.395 over 129 plate appearances, which comprises his only experience at the Triple-A level. Nishida made his Double-A debut in 2024 and then spent the entire 2025 campaign and the start of the 2026 season at Double-A. He got off to a good enough start (.250/.434/.350 in 54 PA) in Birmingham to finally get to the call to Triple-A, and Nishida hit the ground running at the higher level.
Running is a major part of Nishida’s offensive arsenal, as he has 110 steals (out of 140 attempts) during his minor league career. This speed has helped turn a lot of grounders into hits, which partially explains Nishida’s inflated .421 BABIP in Charlotte as more than just a ton of good fortune. Nishida makes a lot of contract and draws a ton of walks, as evidenced by his .410 OBP during his minor league career.
The big flaw in Nishida’s game is a near-total lack of power, as he has two homers and a .340 slugging percentage over 448 games in Chicago’s farm system. This may be why Baseball America and MLB Pipeline don’t list Nishida among the top 30 White Sox prospects, though Chicago’s pretty deep minor league system may also be a factor. Defensively, Nishida has primarily been used as a second baseman and left fielder, though he has a good deal of experience at the other two outfield positions.
The x-factor here is clubhouse impact. As White Sox director of player development Paul Janish tells MLB.com’s Scott Merkin, Nishida is “one of the best baseball players that we have in our organization. He is contagious in the best way. The players around him get better, the teams that he is on win. It’s really hard for me to express how much I think of Rikuu as a player.”
Nishida’s skillset on and off the field makes for an intriguing new addition to a Pale Hose team that has already exceeded expectations with a 26-26 record. It remains to be seen if the Sox can actually contend even in a weak American League, yet it certainly seems like the club has made leaps and bounds in the rebuild process.
Since the Sox are already overloaded with left-handed hitting outfielders, the lefty-swinging Nishida will probably be used in some sort of platoon situation with Chase Meidroth (another low-power source) at second base. Meidroth has been markedly better against lefties than righties in his career, whereas Nishida has started crushing right-handed pitching in 2026. Chicago ranks 11th among all teams in OBP and 14th in stolen bases, so Nishida should help the White Sox improve those already respectable numbers.
MLBTR Chat Transcript
Mark P
- Greetings! We’ll open up the Weekend Chat in a minute or two, once we get some tasty questions rolling in….
B
- What do you think the Phillies do in terms of trades soon or before the deadline they are turning it around but what do they still need? Third base? Right field? Garcia and bohm haven’t been good.
Mark P
- Bullpen will again be a target area, and rotation depth is a need. Nola just isn’t pitching well at all and Painter is inconsistent, leaving the Phils with just three reliable starters.But, you’re correct that 3B/RF will both also be on the radar. Bohm and Garcia are simply running out of time to get their seasons turned around. The Phillies could also use bench depth in general, and someone they obtain for a part-time role could well work their way into more of a regular job at 3B/RF depending on what’s available out there on the market.
Undecided CT
- Somebody just officially announced on his instagram he is actually retiring. I’ve never seen someone change their mind twice on retirement in two days.
Mark P
- Annnnnd, the chat is immediately halted for a couple of minutes since I needed to update our Chris Taylor retirement post.Reading between the lines, I wonder if Taylor decided that he just didn’t feel like going through the grind of the rehab process after fracturing his forearm. It’s understandable how a major injury like that might be the final push to get a veteran player on the fence over into retirement. And hey, can’t blame Taylor for taking some time and a few second thoughts about ending a career path that has dominated most of his life.
Doofus
- How much would the Red Sox have to give up for Yordan Alvarez?
Mark P
- Alvarez is signed through 2028, so unless the Astros decide to entirely blow things up and rebuild, he isn’t being traded. While it is increasingly looking like the Astros may be deadline sellers, Alvarez doesn’t seem likely to be moved.It would require a huge offer of top prospects and MLB-ready young players for the BoSox to pry Alvarez away. Franklin Arias, at least one of Tolle or Early, etc.
Scott Harris
- Of course I’ve failed to build a sufficient offense but can some of my teams shortcomings be attributed time injury?
Mark P
- There are currently 14 players on Detroit’s IL, so yeah, “some” is understating things. One can certainly take issue with how the Tigers chose to build their roster, but there aren’t many teams that can get by with so many key injuries
Guest
- Is it possible the Cards are for real?
Mark P
- “For real” in the sense that they can make the playoffs…..probably not, since their pitching (both the rotation and pen) still doesn’t seem like it’ll hold up over the long haul.”For real” in the sense that they’re looking like a solid team? Absolutely. The Cardinals don’t need to reach the postseason for 2026 to be a nice step in the right direction. Even a .500 record is a big success for a step most expected to be terrible.
Scott
- Who loses there job if the cubs dont make the playoffs, Hoyer or Counsell? Thanks
Mark P
- Hoyer just signed a new extension last summer, whereas Counsell is signed through 2028. Counsell is earning more than $8MM per season, so that would be over $16MM that Cubs ownership would have to eat in the event of a managerial change.This is another situation where the injuries have to be acknowledge, since it isn’t Counsell’s fault that the Cubs’ list of pitching injuries is well into the double figures.
Dave
- Can the Giants find a trade for Chapman? I know he has a no trade clause but moving him is a key for both Schmitt and Eldridge.
Mark P
- I believe June 15 is the first day teams are allowed to trade players they signed to a free agent deal the previous offseason. So that means San Francisco has a few more weeks to gauge their situation before opening the door to Luis Arraez offers. It is far, far more likely that an impending free agent like Arraez is dealt before guys like Chapman on long-term contracts.
- If Arraez is dealt, Schmitt then plays second base, and Eldridge now has a regular spot at either 1B or DH.
Chaim Bloom
- Will I have to ruin the farm system to buy at the deadline if we continue winning?
Mark P
- Bloom’s not going to shift course from this long-planned rebuild just to suddenly trade key prospects for short-term upgrades. If St. Louis is still in the running at the deadline, I can see the Cards making a few modest adds (likely for pitching) but nothing earth-shaking
