Adam Mazur

Marlins Designate Connor Gillispie For Assignment

By Darragh McDonald | June 19, 2025 at 4:15pm CDT

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

By Anthony Franco | June 17, 2025 at 8:50pm CDT

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

By Steve Adams | July 30, 2024 at 3:37pm CDT

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

By Anthony Franco and Darragh McDonald | June 24, 2024 at 5:37pm CDT

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

By Anthony Franco | June 3, 2024 at 8:09pm CDT

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.
