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.
