Brandon Sproat

Mets To Promote Brandon Sproat

By | at

11:45am: The Mets will indeed call up Sproat for his major league debut this weekend, per Chase Ford of MiLB Central. He’ll make his big league debut on Sunday. The Mets will need to open spots on the active and 40-man rosters for Sproat.

9:15am: The Mets have already called up two of the organization’s top three pitching prospects. Nolan McLean has taken the National League by storm, and Jonah Tong looked sharp in his MLB debut last week. The third member of their touted Triple-A trio could soon join them in the majors. SNY’s Andy Martino reports that righty Brandon Sproat is receiving “strong consideration” to make a start for the big league club in the near future.

A possible promotion for Sproat comes at the same time the Mets have been mulling a minor league stint for struggling righty Kodai Senga, who has a 6.56 ERA over his past eight starts (averaging just 4 1/3 innings per outing in that time).

That’s not as straightforward a decision as it might seem. The five-year, $75MM contract Senga signed when he came to MLB from Japan’s Nippon Professional Baseball stipulates that he cannot be optioned to the minors without his consent. It’s not expressly clear that the Mets have asked him about to accept an optional assignment, though Mike Puma of the New York Post implied as much yesterday when writing that the organization expects to know whether Senga would approve the move by this weekend. Puma added that one way or another, the organization expects Sproat to make his big league debut before season’s end.

Sproat, 24, was the Mets’ second-round pick in 2023. The former Florida Gators standout has had an up-and-down year in Triple-A. He struggled to an ERA north of 6.00 in April/May before dominating with a combined 2.22 ERA in June and July. Sproat alternated between quality starts and clunkers throughout August. He’s sitting on a 4.24 ERA overall, and he’s punched out 22.1% of his opponents against a 10.6% walk rate. Those numbers look far better if you toss out the first two months of the season; Sproat has a 3.13 ERA, 25.7% strikeout rate and 10.1% walk rate in his past 14 starts. He tossed seven scoreless frames against the Yankees’ top affiliate his last time out, fanning nine hitters against only two walks along the way.

The uneven nature of Sproat’s season, coupled with the influx of talent from this year’s draft, has dropped him down — or even entirely off — most top-100 lists around the industry. ESPN’s Kiley McDaniel still lists him 83rd in the game, and Baseball America has Sproat at No. 98. Baseball America notes that his turnaround in Syracuse coincided with increased usage of his curveball, changeup and two-seamer, helping to diversify his repertoire and make him less predictable, as opponents had become too keyed-in on his four-seamer. The 6’3″, 215-pound Sproat is sitting 96.4 mph on that four-seamer this season, and both his changeup and slider draw above-average to plus grades from scouts.

While Sproat’s seemingly inevitable addition to the 40-man roster and his MLB debut will come after Sept. 1, he’ll still be eligible for postseason play. Any player in an organization prior to September is eligible for postseason rosters. Technically, the Mets would need to petition for him to be an injury replacement, but teams make this move every year. At times, we’ve even seen top prospects who weren’t on the 40-man roster at the beginning of September get selected to the roster in October make their MLB debuts in the playoffs (e.g. Shane McClanahan, Adalberto Mondesi, Alex Kirilloff).

Mets Notes: Tong, Duran, Siri

By | at

There is some feeling within the Mets organization that right-handed pitching prospect Jonah Tong could make his MLB debut before the 2025 season is up, Mike Puma of the New York Post reports.  Tong only just made his debut with Triple-A Syracuse on August 16 and hadn’t been projected as “a consideration for the Major League roster this year,” Puma writes, but “that stance has changed in recent days.”

The shift is due to both the Mets’ rotation needs, and Tong’s continued excellence in his third pro season.  A seventh-round pick for New York in the 2022 draft, Tong has emerged as a top-100 prospect — Baseball America has the right-hander 42nd on their midseason top 100 list, and MLB Pipeline has Tong in their 44nd spot.  It is easy to see why, as Tong has an absurd 1.43 ERA and 40.5% strikeout rate over 113 2/3 combined innings at the Double-A and Triple-A levels in 2025.  That includes 11 2/3 scoreless innings during his brief time in Syracuse.

Naturally there’s some risk in bringing the 22-year-old up to the Show in such relatively rapid fashion, and Tong’s 10.6% walk rate stands out as a potential weakness to be exploited by big league hitters.  That said, Tong’s unusual delivery could also leave some hitters baffled, not to mention his plus fastball that has a ton of break if relatively little velocity (in the 91-94mph range).

Promoting Tong doesn’t necessarily mean he’d be in the majors for the rest of the season, of course, as the Mets could potentially use him for a spot start during a crowded stretch of the schedule.  New York is six games into a stretch of 26 games in 27 days, with September 4 as the only off-day during that stretch.  This puts even more pressure on a rotation that hasn’t provided much in the way of length or results lately, and the Mets already turned to another rookie in Nolan McLean to take Frankie Montas’ rotation spot earlier this month.

At this point it wouldn’t be a shock to see McLean, Tong, and another top prospect in Brandon Sproat all get onto the mound before the Mets’ season is over.  This need for help from the farm (in addition to any club’s natural reticence about moving top prospects) may have been a reason why the Amazins didn’t make much progress in trade talks with the Twins about Jhoan Duran.

The Mets were loosely linked to Duran’s market just prior to the trade deadline, and the New York Post’s Jon Heyman reported that the Mets weren’t willing to move any of McLean, Tong, Sproat, Jett Williams, or Carson Benge.  This quintet are the consensus top prospects within New York’s farm system, and Baseball America has all five players within their league-wide top-100 prospects list.  Minnesota was known to be seeking at least one top-100 type for Duran’s services, and found such an offer from another NL East club in the Phillies, who landed Duran for Eduardo Tait and Mick Abel.

Duran has looked excellent in Philadelphia, while the Mets have gotten mixed result from their deadline bullpen acquisitions.  Tyler Rogers and Gregory Soto have both pitched well since coming to Queens, but Ryan Helsley has struggled badly.  Shaky pitching on both the bullpen and rotation has contributed to the Mets’ 7-13 record in August, and the Phillies have pulled out to a six-game lead over New York in the NL East.

In other Mets news, manager Carlos Mendoza told reporters (including MLB.com’s Anthony DiComo) on Wednesday that Jose Siri is expected to start a minor league rehab assignment this week.  Siri fractured his left tibia after fouling a ball off his leg back in April, and what was expected to be an absence of 8-10 weeks has now lasted well over four months.  Since he played in only 10 games with the Mets before the injury, Siri figures to need at least a week of minor league action to get fully ramped up for a return to the active roster.

This makes him a candidate for an IL activation once rosters expand on September 1, though Siri will be returning to a more crowded outfield picture.  New York went into the season planning to use Siri and Tyrone Taylor in a center field timeshare, but the deadline acquisition of Cedric Mullins has now created a more traditional lefty-righty platoon up the middle with Taylor.  A player with Siri’s elite glove always has value on a roster, of course, so the Mets could use him as something of a defensive specialist if nothing else.

Mets To Promote Nolan McLean

By | at

The Mets will call up top pitching prospect Nolan McLean to make his MLB debut this Saturday, reports SNY’s Andy Martino. He’ll step into the rotation spot vacated by Frankie Montas’ move to the bullpen. Jon Heyman of the New York Post reported earlier this morning that righty Paul Blackburn was also headed to the bullpen when he’s ready to be reinstated from the injured list, setting the stage for either McLean or fellow prospect Brandon Sproat to make his debut.

As we noted yesterday when the Mets moved Montas to the ’pen, the Saturday start aligns far better with McLean’s turn in the Triple-A rotation than with that of Sproat. McLean has also simply outpitched Sproat this season, though both well-regarded prospects have excelled recently.

The timing of the move likely isn’t a coincidence. Saturday marks the first day on the calendar where there’s not enough time remaining for players to accrue enough service to exhaust their rookie eligibility. By waiting until Saturday to promote McLean, the Mets have ensured that he’ll still qualify as a rookie next season and therefore still be able to earn the Mets potential future draft picks via the league’s Prospect Promotion Incentive (PPI) program. In all likelihood, McLean is just one of several top prospects around the league who’ll be promoted after Aug. 15.

McLean, 24, was the Mets’ third-round pick in 2023. He’s rated as one of the system’s more promising young arms since that selection, but his stock has exploded in 2025 as he’s ripped through Double-A and Triple-A lineups. McLean has pitched a combined 113 2/3 innings between those two levels and compiled a tidy 2.45 ERA while punching out 27.2% of his opponents. His 10.7% walk rate is still too high, but his huge 54.7% ground-ball rate can help to erase a few of those free passes by way of the double-play ball.

This year’s terrific run has not only vaulted McLean toward the top of the Mets’ in-house prospect lists — it’s made him a consensus top-100 prospect in the sport. He sits 37th among all big league prospects at MLB.com, 40th at Baseball America and 53rd at FanGraphs on each outlet’s post-deadline reranking of the sport’s top young talents.

The 6’2″, 215-pound McLean is an Oklahoma State product whose athleticism draws plenty of praise. He was a two-sport star in high school, playing both baseball and football, and he was a two-way player at OSU, where he was a third baseman and outfielder in addition to his work on the mound. He’s since dialed in only on pitching and experienced an uptick in velocity, now sitting 95 mph with a four-seamer that can climb to 98 mph when he needs to reach back for a bit extra. MLB.com’s report on McLean calls his sweeper a “monster” of a pitch with “elite” spin rate. He’s sitting 85.5 mph with that pitch and also mixing in a sinker, cutter and seldom-used changeup.

Because McLean will retain rookie eligibility going into next year, he could earn the Mets a draft pick down the line. If McLean were to win National League Rookie of the Year or finish top-three in NL MVP voting next season, the Mets would gain that pick. Even if McLean doesn’t hit either of those goals, the fact that he’ll be a top-100 prospect who accrued a full year of service as a rookie opens a three-year window for him to net the Mets a compensatory pick based on award voting. If McLean were to land any top-three finish in Cy Young or MVP voting before reaching arbitration, the Mets would still gain a pick. Players can only net their team one pick under the league’s PPI program, but the timing of his promotion means McLean could do so at any point from 2026-28.

Setting aside the PPI aspect of the promotion, McLean’s promotion comes at a time when he cannot accrue a year of service this season. He’ll be controllable for at least six full years beyond the current campaign — potentially more than that, depending on whether he’s optioned at any point in the future. The earliest he could become a free agent would be after the 2031 season, and the earliest McLean could qualify for arbitration would be following the 2028 season.

Mets Move Frankie Montas To Bullpen

By | at

The Mets will move struggling right-hander Frankie Montas from the rotation to the bullpen, manager Carlos Mendoza announced Tuesday (link via Anthony DiComo of MLB.com). The team has not yet announced who will start in place of Montas on Saturday. The Mets have righty Paul Blackburn on a minor league rehab assignment, but Mendoza indicated that Blackburn will make at least one more rehab appearance and is not an option to step into Montas’ rotation spot this weekend.

Notably, Saturday is the first day that prospects can be promoted to the major leagues but still fall shy of the requisite 45 days on the active roster that exhausts a player’s rookie status. In other words, beginning Saturday, the Mets will be able to turn to a top prospect like Nolan McLean or Brandon Sproat without burning either pitcher’s rookie eligibility. That’s key for teams with top-100 prospects, as promoting those prospects early in the 2026 season can then net the teams a compensatory draft pick, based on Rookie of the Year voting.

It’s been a miserable season for the veteran Montas, who inked a surprisingly strong two-year, $34MM contract with an opt-out provision over the winter. That opt-out is a moot point by now, with the 32-year-old righty being relegated to bullpen work after logging a 6.38 ERA in his first eight appearances of the year (36 2/3 innings).

Montas began the season on the injured list due to a lat strain and didn’t pitch in the majors until late June. He’s allowed four or more earned runs in four of seven starts and has yet to complete six innings in an outing. Setting aside a solid season debut in which he tossed five shutout frames, Montas has been clobbered for a 7.39 ERA and yielded an average of 2.27 homers per nine innings pitched in six starts and one three-inning relief appearance (his most recent outing).

It appears that Montas won’t get the opportunity to improve on that rotation performance anytime soon. It’s difficult to fathom a scenario where he’d turn down the $17MM player option he’s facing at season’s end, so it’s in the Mets’ best interest to get him back on track, but their recent play doesn’t afford them the luxury of keeping a struggling veteran in the rotation while he tries to sort things out.

The freefalling Mets, who’ve lost seven in a row, currently have Kodai Senga, Sean Manaea, Clay Holmes and David Peterson in the rotation. Sproat and McLean stand as the two most logical replacements. (Fellow top prospect Jonah Tong was only just promoted to Triple-A and has yet to throw a pitch there.) Sproat last pitched Aug. 7 and would be on eight days’ rest, whereas McLean pitched on the 10th. Based on their current schedules, McLean seems like the more straightforward option, and he’s pitched more effectively this season anyhow.

Mets Prioritizing Bullpen Help

By | at

The Mets have several areas where they could plausibly pursue upgrades prior to next week’s trade deadline, but president of baseball operations David Stearns indicated yesterday that his primary focus is on improving the bullpen (link via ESPN’s Jorge Castillo).

Mets relievers have been a middle-of-the-pack unit overall, ranking 13th with a combined 3.87 ERA on the season. They’ve struggled to a 5.30 mark over the past month, however, due in no small part to injury. A.J. Minter’s season ended in early May when he required surgery to repair a torn lat. Fellow southpaw Danny Young had Tommy John surgery that same month. Righties Max Kranick and Dedniel Nunez both went down with season-ending arm injuries as well.

The Mets have used a staggering 30 different relief pitchers this season, including 23 over just the past 30 days. They’ve treated the final couple spots in the relief corps as a revolving door, frequently shuttling in waiver claims and minor league signees when they need a fresh arm, than designating those players for assignment in favor of the next arm that comes down the conveyor belt. It’s led to a dizzying number of Mets transactions and constant turnover among the relief corps. Many of those stopgaps have been hit hard, and mainstays Reed Garrett and especially Huascar Brazoban have struggled over the past month.

Edwin Diaz, Ryne Stanek, Garrett and Brazoban have been constants in Carlos Mendoza’s bullpen. The Mets clearly have room to add multiple arms and should likely be expected to do just that. They were in the mix to sign David Robertson before he opted to reunite with the Phillies, and they reportedly have some interest in Twins left-hander Danny Coulombe (at a time when Minnesota is said to be increasingly open to offers on rental players).

The Mets have been tied to rotation upgrades, reportedly showing interest in Pirates righty Mitch Keller and in Marlins righty Edward Cabrera. Stearns downplayed the possibility of adding to his starting staff, however, stating that he’s “comfortable” with the in-house group and its ability to navigate a postseason series. If Kodai Senga, Sean Manaea, Clay Holmes, David Peterson and Frankie Montas can all remain healthy, New York’s starting five indeed looks sharp, but health is hardly a given. Each of Senga, Manaea and Montas has had a monthslong IL stint within the past 15 months. Holmes is in his first season stretching back into a rotation role after years as a high-leverage reliever.

Similarly, while Stearns acknowledged that he expects to explore the market for center fielders, an acquisition isn’t necessarily likely. The Mets have been pleased with Jeff McNeil’s increased comfort in center and Tyrone Taylor’s defensive play. “[T]he bar to improve center field has probably risen over the past, let’s say, two weeks,” Stearns said.

Stearns naturally did not decisively rule out a center field addition, but it’s a thin market in terms of options. Cedric Mullins is likely available in Baltimore, and the O’s have multiple relievers available (e.g. Gregory Soto, Seranthony Dominguez and perhaps Andrew Kittredge). Similarly, if the Mets already have interest in Minnesota’s Coulombe, they could look into both him and old friend Harrison Bader, who’s on a one-year deal and has performed well on both sides of the ball in the Twin Cities. The White Sox have both Luis Robert Jr. and Mike Tauchman available. The former has finally begun to heat up in recent weeks, while the latter has hit well for much of the season. If the Mets wanted to take a bigger swing, they could try to pry Oneil Cruz from Pittsburgh. He (reportedly) is not completely off the table, but the asking price would surely be extreme.

The Mets are willing to deal from their collection of young infielders, which includes Brett Baty, Mark Vientos, Ronny Mauricio and Luisangel Acuña. They also have several pitching prospects on the cusp of the majors, including Brandon Sproat, Nolan McLean and Blade Tidwell. Stearns noted that any of the three could be a candidate to join the bullpen down the stretch but added the Mets will be cautious with such decisions, as once a starting pitcher is ramped down to a bullpen role during the season, it’s hard to stretch him back out.
