Marlins Sign Austin Slater To Major League Deal
March 25th: The Marlins announced today that Mazur has been placed on the 60-day injured list. In a separate announcement, the club made the Slater deal official. He’ll join Heriberto Hernandez as a righty outfielder off the bench behind Marsee, Caissie, and Conine.
March 24th: The Marlins are in agreement with outfielder Austin Slater on a major league deal, reports Craig Mish of SportsGrid. He just opted out of a minor league deal with the Tigers a few days ago. He’ll make $1MM plus bonuses, per Kevin Barral of Fish on First. The Marlins will need to open a 40-man roster spot but that should be as easy as transferring right-hander Adam Mazur to the 60-day injured list. Mazur underwent Tommy John surgery a few weeks ago and will miss the entire season.
Slater, 33, just had a strong camp with the Tigers. He stepped to the plate 36 times in 15 games and slashed .267/.389/.467. Detroit’s roster is fairly crowded, however. They are going to carry prospect Kevin McGonigle on the Opening Day roster and have bumped outfielder Wenceel Pérez to the minors.
The Marlins will take advantage of that roster crunch by scooping up Slater. In his career, he has generally combined solid defense in all three outfield slots with strong offense against left-handed pitching. His overall batting line is .248/.336/.384. That’s almost exactly league average, translating to a 101 wRC+. That includes a .267/.357/.430 line and 119 wRC+ against southpaws, compared to a .227/.311/.329 slash and 80 wRC+ otherwise.
That profile should fit well in the Miami outfield. The Marlins are slated to begin the season with Kyle Stowers on the injured list, which will leave Jakob Marsee, Owen Caissie and Griffin Conine in the outfield. All four of those guys are lefties, so Slater should have plenty of chances to slot in against southpaw opponents.

Marlins’ Adam Mazur Undergoes UCL Surgery
12:05pm: Mazur underwent a UCL reconstruction (Tommy John surgery) and had an internal brace installed, reports De Nicola. The estimated timetable for his return from that hybrid procedure is 13 to 14 months.
9:00am: Marlins righty Adam Mazur will undergo elbow surgery today and miss the entire 2026 season as a result, MLB.com’s Christina De Nicola reports. Mazur wasn’t locked into Miami’s rotation but was among the top depth options in the event of an injury to one of Sandy Alcantara, Eury Pérez, Chris Paddack or likely fourth and fifth starters Max Meyer and Braxton Garrett. It’s not yet clear which type of procedure he’ll require. Mazur recently reported elbow discomfort to the team and was quickly sent for an evaluation with renowned surgeon Keith Meister.
Mazur, 24, came to the Marlins alongside infielder Graham Pauley, top pitching prospect Robby Snelling and minor league infielder Jay Beshears in the 2024 trade that sent lefty Tanner Scott and righty Bryan Hoeing to the Padres. He’s a 2022 second-rounder who posted big numbers up through the Double-A level but has run into some trouble at both the Triple-A level (5.03 ERA, 168 1/3 innings) and in more limited major league work (6.22 ERA, 63 2/3 innings).
In 2025, Mazur split the season between Triple-A Jacksonville and Miami, tossing 107 1/3 innings with a 4.36 ERA at the former and 30 innings with a 4.80 ERA with the latter. He turned in solid strikeout and walk rates in Jacksonville but was far too homer-prone to keep his ERA down. Homers were less of an issue in his six big league starts, but he recorded a bottom-of-the-barrel 13.7% strikeout rate in his 30 MLB frames.
Having traded Edward Cabrera to the Cubs and Ryan Weathers to the Yankees, the Marlins entered camp with Alcantara, Pérez and free agent signee Paddack locked into rotation spots. Meyer and Garrett have both pitched only four official spring innings, but they’re both former top-10 picks and top prospects who have experienced success in the majors previously.
Garrett notched a 3.63 ERA in 247 2/3 innings from 2022-23 before a 2024 UCL surgery wiped out his entire 2025 season. Meyer has a 5.29 ERA in 25 career starts but has had big starts to his season in both 2024 and 2025. Miami optioned him in 2024 despite that big start, keeping him down for months and leaving Meyer six days shy of the service time he’d have needed to be a free agent following the 2028 season instead of the 2029 season. In 2025, a hip injury surfaced and eventually required season-ending surgery.
Depth options on the 40-man roster include swingman Janson Junk (4.17 ERA, 110 innings in 2025), Ryan Gusto (acquired from the Astros in last summer’s Jesús Sánchez trade), Bradley Blalock (acquired from the Rockies in January) and 2020 second-rounder Dax Fulton (healthy again after multiple injuries, including a June 2023 internal brace procedure). The aforementioned Snelling and fellow left-hander Thomas White are the two most notable rotation arms in waiting; both rank among baseball’s top 100 prospects, but neither has needed to be added to the 40-man roster just yet. That’ll very likely change in ’26, as both are considered nearly MLB-ready. White is the more touted of the two but has a bit less experience in the upper minors, given his status as a 2024 draftee compared to Snelling, a 2023 draftee.
Since Mazur is on the 40-man roster, has big league experience and was in major league camp at the time of injury, he’ll be placed on the major league injured list. If and when Miami needs an additional 40-man roster spot, he’ll be placed on the 60-day IL. Mazur will accrue a full year of service time and retain the lone minor league option year he has remaining. Miami will be able to control him via arbitration through at least the 2031 season.
Adam Mazur To See Specialist For Elbow Discomfort
Marlins right-hander Adam Mazur is going to see renowned surgeon Dr. Keith Meister about some elbow discomfort, per Christina De Nicola of MLB.com. He has already had some imaging done, per Craig Mish of SportsGrid.
At this point, there aren’t many details, but it’s always a bit ominous when concerns arise with a pitcher’s elbow. Mazur was acquired from the Padres at the 2024 deadline in the deal headlined by Tanner Scott. He served as optionable rotation depth for Miami last year, making six big league starts with a 4.80 earned run average and 13.7% strikeout rate. In 22 Triple-A appearances, he had a 4.36 ERA and a much more encouraging 22.2% strikeout rate.
He was likely going to start 2026 in a similar role. He still has one option season remaining and wasn’t likely to be one of the top five starters to begin the season. Even though the Marlins traded away Edward Cabrera and Ryan Weathers this winter, they still project to go into the year with a rotation featuring Sandy Alcantara, Eury Pérez, Chris Paddack, Max Meyer and Braxton Garrett. They also have Janson Junk in the mix. He is out of options and should be on the big league roster somewhere, perhaps in a long relief role if there’s no room in the rotation.
Pitching injuries are inevitable and a team will need far more than just five or six starters to get through a season. The Marlins had 15 different guys make at least one start last year, for instance. Mazur was once of 11 guys to make at least three starts.
The depth has been challenged a bit here during spring training. Junk had an ankle sprain a couple of weeks ago but he seemed to be fine now. Per De Nicola, he is scheduled to make his Grapefruit League debut tomorrow. Prospect Thomas White recently suffered an oblique strain and will be sidelined for three to four weeks.
The Fish have Dax Fulton, Bradley Blalock and Ryan Gusto as optionable starters currently on the 40-man. Prospect Robby Snelling has 11 Triple-A starts under his belt and should push for a major league debut in 2026. If Mazur needs to miss some time, it would increase the likelihood of the Marlins turning to those other arms.

Marlins Designate Derek Hill For Assignment
The Marlins announced a big series of roster moves today. Right-hander Edward Cabrera has been reinstated from the 15-day day injured list and outfielder Griffin Conine from the 60-day IL. To open active roster spots, right-hander Adam Mazur and outfielder Joey Wiemer have each been optioned to Triple-A Jacksonville. To open a 40-man spot for Conine, outfielder Derek Hill has been returned from his rehab assignment, reinstated from the 10-day injured list and designated for assignment.
Hill, 29, was claimed off waivers from the Giants in August of last year. Since that claim, he has generally continued to have roughly the same level of production before he came to Miami. Though he can make some nice catches and steal a few bases, he has generally been a guy with subpar offense, thanks to poor strikeout and walk numbers.
He has made a few trips to the injured list this year, two due to a left wrist sprain, another due to a left middle finger sprain, and most recently a right hamstring strain. Around those IL trips, he has appeared in 53 games for the Marlins. In his 141 trips to the plate, just 6.4% of those have resulted in him taking a walk while 32.6% of them ended in strike three. His .213/.275/.331 batting line translates to a 68 wRC+.
Though he has seven stolen bases on the year and strong defensive grades, the bat was dragging him down. He is out of options and can’t be easily sent to the minors. He has crossed three years of big league service time this year, meaning he was going to qualify for arbitration this winter. It seems the Marlins weren’t planning to tender him a contract, so they have cut him early in order to open a roster spot for their other moves today.
Since the trade deadline has passed, he will be on waivers in the coming days. There wouldn’t be much short-term appeal for other clubs, since the season is almost over and he wouldn’t be postseason eligible for any claiming team. He can be controlled for three seasons after this one, but a club would only grab him if they thought he was worth an arbitration raise for 2026. If he clears waivers, he will have the right to elect free agency.
The returns of Cabrera and Conine are also potentially notable here, as the Marlins are clinging to a tiny hope of a miracle run to finish the season. They are four games back of the Reds and Mets with six games left to play. Both players were performing well earlier this year, so perhaps they can give Miami a boost for an incredible sprint to the finish line.
Cabrera’s return is also notable for the upcoming offseason. He has had something of a breakout here in 2025, as his results have kicked up a notch. He has always been able to get strikeouts and ground balls, but his stock has been held back by poor control and some injury concerns.
He has softened both of those worries a bit here in 2025. He came into this year with a 13.3% walk rate but has managed to limit the free passes to a 7.7% clip this season. He has also stayed healthy enough to log 128 2/3 innings. He had never before hit the century mark, so that’s easily a career high.
An elbow sprain did put him out of action at the start of this month, but he has managed to return three weeks later. If he can stay healthy and effective in the final week, that could give him and the Marlins some peace of mind about him going into 2026.
The Fish will are theoretical candidates to trade a starting pitcher this winter. Rumors surrounding Cabrera and Sandy Alcantara were common this summer but the Marlins held both beyond the trade deadline. Going into next season, their rotation mix includes those two as well as Eury Pérez, Ryan Weathers, Janson Junk, Braxton Garrett, Max Meyer, Ryan Gusto, Mazur, Dax Fulton and Freddy Tarnok, with prospects Thomas White and Robby Snelling currently lurking in Triple-A. It’s possible to imagine the Marlins revisiting the possibility of trading Alcantara or Cabrera this winter, which could give Cabrera’s return today a bit of extra intrigue.

Marlins Designate Connor Gillispie For Assignment
The Marlins announced that they have selected right-hander Robinson Piña, a move that was reported earlier. In corresponding moves, righty Adam Mazur has been optioned to Triple-A Jacksonville and righty Connor Gillispie has been designated for assignment.
Gillispie, 27, was claimed off waivers from Atlanta in January. He earned a rotation job to start the season but couldn’t hold it. In six starts, he allowed 25 earned runs in 26 innings, leading to an unsightly 8.65 ERA.
That got him optioned down to Triple-A, where he has since logged 33 2/3 innings with a 4.28 ERA. While that was obviously a big improvement, luck was a big factor. He struck out just 15.7% of batters faced in the minors while giving out walks at an 11.4% clip. If it weren’t for a tiny .161 batting average on balls in play, he would have fared far worse, hence his 6.55 FIP.
He’s now been nudged off the 40-man roster and will likely end up on waivers in the coming days. His minor league work prior to this year was better. From 2021 to 2024, he logged 406 innings on the farm with a 4.12 ERA. His 9.6% walk rate was a tad high but he also punched out 24.1% of opponents. He is still optionable for the rest of this year and one further season, so perhaps a club with a need for depth and a plan to get Gillispie on track could have interest. If he clears outright waivers, he would stick with the Marlins as non-roster depth.

Marlins To Recall Adam Mazur
The Marlins will recall righty Adam Mazur to start tomorrow evening’s game against Philadelphia, manager Clayton McCullough told reporters (including Daniel Álvarez-Montes of El Extrabase). He’ll go against Ranger Suárez in his team debut. SportsGrid’s Craig Mish first reported that Mazur was likely to get the call. He’s already on the 40-man roster, so the Fish only need to make an active roster move involving a pitcher.
It’s not a big league debut for the 24-year-old Mazur. He took the ball eight times for the Padres last summer. The former second-round pick struggled in his first look at MLB hitters, giving up a 7.49 ERA through 33 2/3 innings. He’d only had five Triple-A starts at the time, as San Diego was pressed into calling him up by injuries to their more established starters. The Padres optioned him back to Triple-A just before the trade deadline.
Three days later, Mazur was on the move. The Marlins acquired him as part of the return for Tanner Scott and Bryan Hoeing last July. Mazur has been on optional assignment to Triple-A Jacksonville for the better part of a calendar year. He struggled over eight starts there last year but has posted better numbers this season. Mazur owns a 3.62 ERA with a 22.2% strikeout percentage and tidy 6.5% walk rate. He has allowed home runs at an elevated rate, but it’s a generally solid performance to earn him his first call to loanDepot Park.
Miami has been operating with a four-man rotation of Sandy Alcantara, Eury Pérez, Cal Quantrill and Edward Cabrera. They lost Max Meyer and Ryan Weathers to injury and have been utilizing bullpen games to handle the fifth starter role. McCullough didn’t specify whether Mazur will get more than one start for this recall, but it stands to reason that he’ll get a real rotation opportunity at some point this year. Alcantara, Quantrill and potentially Cabrera could all be in trade discussions this summer. Quantrill also left tonight’s start early with a leg issue, though McCullough said postgame that it was just a cramp (via Isaac Azout of Fish on First).
Padres To Acquire Tanner Scott, Bryan Hoeing
3:37pm: The Padres are sending left-hander Robby Snelling and right-hander Adam Mazur to Miami, reports ESPN’s Alden Gonzalez. Mish adds that infielder/outfielder Graham Pauley is also part of the return, and Daniel Alvarez Montes of El Extra Base reports that infielder Jay Beshears is the fourth and final player in the return. It’s a major haul that’ll send three of the Padres’ top remaining prospects (Snelling, Mazur, Pauley) to Miami in exchange for the pair of relievers.
3:32pm: The Padres are finalizing a deal to acquire closer Tanner Scott from the Marlins, ESPN’s Jeff Passan reports. Craig Mish of SportsGrid and the Miami Herald adds that righty Bryan Hoeing is also going to San Diego in the deal.
It’s the latest trade market strike for a Padres club that has already added righty Jason Adam in a deal with the Rays and that picked up Luis Arraez in another early-season blockbuster with Miami. The Scott trade is still pending the medical review of the players involved.
Scott, 30, has one of the lowest ERAs in the majors this season, with a pristine 1.18 mark in 45 2/3 innings of work. He’s averaged 97.1 mph on his heater, fanned 29.1% of his opponents and induced grounders at a hearty 49% clip. The flamethrowing lefty has picked up 18 saves for Miami on the season and tacked on another 12 saves in 2023, when he tossed 78 innings of 2.31 ERA ball.
Impressive as Scott’s earned run average has been, he’s seen a resurgence of the command troubles that plagued him for his entire career prior to the 2023 campaign, when he went from a lifetime 14.2% walk rate to a tidy 7.8% mark. Scott has issued a free pass to a glaring 14.8% of his opponents this season, although a good portion of his command troubles came in the season’s first few weeks. He’s posted a 0.49 ERA, 32.6% strikeout rate and more manageable (but still too high) 10.9% walk rate dating back to April 20. At this point, last year’s strong walk rate looks like an aberration.
Scott is playing the season on a one-year, $5.7MM contract. He’s a pure rental for the Friars, barring an extension, and won’t net them any draft compensation, as his midseason trade renders him ineligible for a qualifying offer. The Padres are ponying up on a big offer in hopes of building a dominant bullpen that can help them navigate short postseason series with off-days baked in throughout the schedule. Scott and Hoeing join the aforementioned Adam, Robert Suarez (1.51 ERA in 41 2/3 innings), Jeremiah Estrada (2.92 ERA in 39 2/3 frames), Adrian Morejon (2.74 ERA in 42 2/3 innings) and Yuki Matsui (3.45 ERA in 47 2/3 frames) to round out a formidable relief corps.
Also joining the revamped bullpen is the 27-year-old Hoeing. He’s not nearly as established as Scott and the majority of his new bullpen-mates but is nevertheless enjoying a strong 2024 campaign. In 30 frames, he’s logged a 2.70 ERA with a below-average but respectable 20.2% strikeout rate against a 7.3% walk rate. Hoeing has kept the ball on the ground at a 48.9% clip in part because of a sinker that averages a solid 93.7 mph. He throws that pitch just over half the time and pairs it with a slider-splitter combo — and a rarely-used four-seamer — that helps keep both lefties and, to a lesser extent, righties off balance.
Although Hoeing will turn 28 in October, he’ll finish the season with just two years of MLB service time. That’ll make him controllable for the Padres not only for the stretch run in ’24 but for four additional seasons thereafter. He won’t be arbitration-eligible until the 2025-26 offseason at the earliest, and he still has a pair of minor league option years remaining. That gives them a potential long-term piece in the ‘pen, which the Friars surely coveted in exchange for giving up what looks like an impressive collection of young talent that’ll continue to beef up a rapidly improving Marlins system.
Among the names going to the Marlins in the deal, the 23-year-old Mazur and 23-year-old Pauley have both made their big league debuts. Mazur is the more highly regarded of the two, having been a second-round pick back in 2022. He’s struggled to a 7.49 ERA through his first five big league appearances but has posted a 4.39 ERA with a 24.7% strikeout rate and outstanding 5% walk rate in 55 1/3 innings between Double-A and Triple-A this season.
Both Baseball America and MLB.com ranked Mazur as the Padres’ No. 4 prospect, calling him a potential mid-rotation starter on the back of 60- or 70-grade command. FanGraphs’ Eric Longenhagen offered a more measured approach recently, noting that Mazur’s command struggles in the majors and some lost life on his heater have him looking more like a potential reliever. There’s some variance in potential outcomes, as is to be expected with a 23-year-old starter who’s rapidly climbed the minor league ranks, but Mazur has the potential to be a rotation piece for several years in Miami.
Pauley went 4-for-32 in a tiny cup of coffee with the Padres earlier this season and has struggled through a down year in Triple-A, hitting just .228/.342/.390. Even as he’s stumbled there, however, he’s drawn walks at a 13.9% clip and played all over the diamond, logging innings at first base, second base, third base and in both outfield corners.
Again, both BA and MLB.com are more bullish on Pauley, ranking him inside the Padres’ top-six prospects, while FanGraphs pegged him at 13th earlier this month. He raked at a .308/.393/.593 clip across three minor league levels in 2023, and his versatility adds value to his profile.
Pauley was primarily a third baseman early on but began moving around the field as the Padres looked to make him more versatile (understandable with Manny Machado entrenched at the hot corner in San Diego). He won’t face that type of permanent roadblock in Miami — Jake Burger could move across the diamond following the trade of Josh Bell — giving Pauley a potential audition as an everyday third baseman or at least a bat-first utilityman.
While Mazur and Pauley have both reached the majors, it’s arguably Snelling who’s the headliner of the deal. The 20-year-old has struggled in the minors this year, but that’s in large part due to an aggressive assignment to Double-A, where he’s one of the league’s youngest players.
The No. 39 overall pick in 2022, Snelling breezed from Low-A to Double-A last season, posting 103 2/3 innings of 1.86 ERA ball with a combined 28.4% strikeout rate and 8.2% walk rate as a 19-year-old. He’s been roughed up for a 6.01 ERA in his second shot at Double-A — he only pitched 17 innings there last year — with strikeout and walk rates that have trended in the wrong direction (20.2% and 10%, respectively). Still, Snelling ranks as the game’s No. 44 prospect at MLB.com (though he’s fallen off top-100 lists at FanGraphs and BA).
Rounding out the Marlins’ return is Beshears, a 22-year-old Duke product whom the Padres selected in the sixth round of last year’s draft. He’s hitting .261/.373/.377 between Low-A and High-A this season, with a gaudy 13.6% walk rate against just an 18.7% strikeout rate. He’s a power-over-hit infielder who ranked near the back of the Padres’ top 30 on most publications, in part due to questionable arm strength that makes him a tough fit for the left side of the infield.
The Padres have held firm on their reluctance to trade top-ranked prospects like catcher Ethan Salas and shortstop Leodalis De Vries, but the remainder of their system has been picked over in the past four months thanks to acquisitions of Scott, Hoenig, Adam, Arraez and (in spring training) Dylan Cease. They’re a Wild Card team at best in all likelihood, but president of baseball operations A.J. Preller has never encountered a star player he didn’t love on the trade market and isn’t deviating from old habits in 2024. With Salas and De Vries still in tow, the Padres have the firepower to make another blockbuster add if they soften their stance on that pair, and the timing of this trade gives Preller a bit more than an hour to survey the remainder of the trade market.
Padres Place Fernando Tatis Jr. On Injured List
Monday marked a busy day on the transaction front for the Padres. San Diego placed star right fielder Fernando Tatis Jr. on the 10-day injured list, retroactive to June 22, with a right femoral stress reaction. The Friars also optioned outfielder José Azocar and right-hander Jhony Brito to Triple-A El Paso. Filling the three spots on the active roster: outfielder Bryce Johnson, infielder Eguy Rosario and right-hander Adam Mazur. Johnson was not on the 40-man roster, but the Friars have had a vacancy for weeks.
The Tatis injury is the biggest development. Manager Mike Shildt indicated that Tatis could play through the issue but that it wouldn’t fully heal without rest (X link via Annie Heilbrunn of the San Diego Union-Tribune). The team isn’t providing a specific return timetable, though they expect it to be longer than the minimal 10 days. It’s not out of the question that Tatis is sidelined through the All-Star Break.
Any absence is a major blow to the San Diego lineup. Tatis has been one of the top outfielders in the National League this year. He’s hitting .279/.354/.468 with 14 home runs across 345 plate appearances. Tatis has trimmed his strikeout rate to a career-low 20.6% clip while making hard contact on a massive 53.4% of batted balls. There’s no easy way to replace that kind of production.
It seems the Pads could roll with a David Peralta/Johnson platoon in right field for the time being. The lefty-swinging Peralta is only hitting .204/.306/.241 over 25 games since being called up last month. Johnson, a switch-hitter, has yet to play in the majors this season. San Diego signed the 28-year-old to a minor league deal in January. The former Giant has reached base at a massive .430 clip over 259 plate appearances with El Paso. Johnson is hitting .301 while drawing walks more than 15% of the time. He has also swiped 18 bases in 20 attempts. Johnson is in the lineup against Patrick Corbin this evening.
Mazur returns to the big leagues just three days after being optioned. (He didn’t need to wait the minimal 15 days because he is technically being recalled to replace the injured Tatis.) In actuality, he’s more directly a replacement for Yu Darvish. San Diego anticipated the right-hander returning from the injured list tomorrow. However, Heilbrunn tweets that Darvish is battling some inflammation in his throwing elbow. While Shildt downplayed the long-term concern, he won’t be ready for MLB action tomorrow.
Darvish has been out since May 30 with a strained left groin. The late revelation of a new elbow concern is suboptimal, though it doesn’t seem the Padres are especially alarmed at this point. The injury will force San Diego to turn back to the 23-year-old Mazur for his fifth big league start. The former second-round pick has allowed 14 runs over his first 17 1/3 innings. Mazur has walked more than 19% of batters faced, a bizarre issue for a pitcher who has shown pristine control in his minor league career.
Jeff Sanders of the San Diego Union-Tribune observed (on X) that Johnson was in the clubhouse prior to the team announcement.
Padres To Select Adam Mazur
The Padres are promoting pitching prospect Adam Mazur, as first reported by FanSided’s Robert Murray (on X). The right-hander is listed as the probable starter for tomorrow evening’s matchup with the Angels.
San Diego selected Mazur in the second round of the 2022 draft. The University of Iowa product worked to a 2.81 ERA in 96 innings during his first professional season. Baseball America ranked the Saint Paul native as the #6 prospect in the organization over the winter. BA’s offseason scouting report credited Mazur with a mid-90s fastball and a plus slider to lead a four-pitch mix. The outlet also lauded his plus-plus (70-grade) control, no surprise for a pitcher who walked a minuscule 4.3% of batters faced a year ago.
The Padres started Mazur at Double-A San Antonio this year. He breezed past the level, working to a 1.95 ERA with a near-27% strikeout rate while issuing only five walks in his first six starts. He’s had a tougher time since being promoted to Triple-A El Paso last month. Over four appearances in the Pacific Coast League, he has been tagged for 15 runs in 19 innings. Mazur has given up four homers in a tough setting for pitchers, but he has fanned 18 opponents (22.8%) against four walks (5.1%).
Despite Mazur’s lack of Triple-A experience, he’ll get his first look at major league hitters in Anaheim. The Padres lost both Joe Musgrove and Yu Darvish to the injured list over the weekend. That left a pair of vacancies behind Michael King, Dylan Cease and Matt Waldron. San Diego recalled right-hander Randy Vásquez for a start against the Royals on Saturday. Mazur will get at least one start and could take a couple turns through the rotation. The Padres don’t have an off day until June 13.
San Diego’s 40-man roster is full. They’ll need to make a corresponding move to select Mazur’s contract, though that’ll likely be a procedural transaction. Glenn Otto and Tucupita Marcano have been on the injured list all season and could be moved to the 60-day IL without impacting their eligibility to return. (Marcano is reportedly under MLB investigation for allegedly placing bets on baseball last year.) The Padres will need to option a pitcher as a corresponding active roster move once they officially call Mazur up.
