What challenges has Matt Allan faced in his career leading up to this point? How did he perform in his recent comeback outing? What are the expectations for Nolan McLean after his transition to full-time pitching? What were the highlights of his first start this season? How did Dedniel Núñez’s recent performance compare to his previous outings, and what is the team’s focus for his development?
Here's how some of the Mets' top prospects fared on the mound Sunday afternoon…
Former top prospect back on mound
Matt Allan’s pro career hasn’t quite gone as planned thus far.
The young right-hander was once viewed as the Mets’ top pitching prospect — but he’s been plagued by numerous different arm issues over the past couple of seasons and hasn’t taken the mound since 2019.
But after working his way back this offseason, Allan is finally healthy and ready to roll.
He made his first appearance in nearly six years on Sunday afternoon with the Single-A St. Lucie Mets and fared extremely well — allowing just two hits while walking one and striking out five across 2.2 innings of work.
The 23-year-old threw 28 of his 44 pitches for strikes and touched 97 mph.
The biggest thing will be for Allan to stay healthy — but if he can continue putting together strong performances like this one, he might be able to work his way through the system relatively quickly given his age.
Nolan McLean picks up where he left off
McLean is one of the more intriguing Mets prospects to keep an eye on.
He came into the organization as a two-way player out of Oklahoma State, but opted to transition into a full-time pitcher last season, and pitched to a strong 2.36 ERA over his final seven starts.
After working all offseason many believe that 2025 will be a breakout year for the 23-year-old, and Sunday's outing was certainly a strong start.
McLean was phenomenal across four scoreless innings of work with Double-A Binghamton, allowing just three hits while striking out eight and generating 15 swing-and-misses.
He threw 54 of his 70 pitches for strikes, and his 70-grade sweeper was on full display.
McLean is the Mets' third-ranked prospect on Joe DeMayo's updated Top 30 list heading into this season, and he could quickly find himself in Triple-A if he's able to build off his stellar season debut.

How Dedniel Núñez fared in Syracuse
Núñez has looked good with Syracuse since being sent down at the end of spring training — but he finally put together his first rough outing on Sunday afternoon.
The right-hander entered in relief of Luis Moreno in the top of the seventh and immediately allowed the next two batters to reach as Ismael Mungia singled and stole second before scoring on an Everson Pereira two-run homer to right-center.
He bounced back to retire the next batter, bringing his outing to an end.
Núñez has now pitched to a 7.36 ERA across three minor league outings, but manager Carlos Mendoza said earlier in the day that they weren't too concerned about the results.
“We just want him to continue to take the baseball. We’re not looking at results right now,” Mendoza explained. “I think it’s just more building him up. I think it’s twice that he’s gone multiple innings, and that’s what we want to see, his ability to recovery.
“I think it’s just the recovery. Are you going to be able to take the baseball two days after you throw two innings? Are you going to be able to bounce back, you throw one inning, and not necessarily back-to-back, but what about two out of three? That’s what we’re preparing him for.”
Mets Prospect Notes: Nolan McLean Shines in Season Debut, Matt Allan’s Strong Return
The New York Mets’ farm system has long been a topic of intrigue, with a mix of high-ceiling prospects and seasoned players vying for a shot at the big leagues. As the minor league season unfolds, all eyes have been on some of the standout performances from emerging talents. Notably, Nolan McLean’s impressive season debut and Matt Allan’s robust return to the mound have set the stage for excitement within the organization and among Mets fans.
Nolan McLean: A Star in the Making
Nolan McLean, an outfielder who was selected by the Mets in the recent draft, has made quite an impression since stepping onto the field. In his season debut, McLean showcased his electric skill set, combining speed, power, and an impressive baseball IQ that aligns with the Mets’ vision for a dynamic lineup.
In his first game, McLean launched a double to left field and followed up with a home run, ending the game with three RBIs and a walk. His performance didn’t just highlight his raw talent but also underscored a maturation in his approach at the plate. McLean appears to have taken strides in not only making contact but also driving the ball with authority, a critical element the Mets need as they look to bolster their lineup depth.
Defensively, McLean also demonstrated his ability to cover ground quickly, showcasing an arm that could play well at the major league level. His speed on the basepaths and defensive skills provide a dual threat that has the potential to evolve into a game-changer for the Mets. Scouts have taken note of his keen ability to read pitches and adjust mid-game, which speaks to his dedication to refining his skills and learning from each outing.
The Mets have long prioritized drafting and developing talent that can contribute not just this season but for years to come. McLean’s standout debut is just the tip of the iceberg, and if he continues to pair his athletic prowess with consistent performance, he could become an indispensable asset for the team shortly.
Matt Allan: A Strong Comeback
Equally noteworthy is the return of pitcher Matt Allan, who had been sidelined with injuries that jeopardized his career trajectory. After undergoing Tommy John surgery, many speculated about his long-term viability as a budding ace in the Mets’ rotation. However, Allan has silenced many critics with an emphatic comeback that displays his resilience and talent.
In his first start of the season, Allan struck out eight batters over five strong innings, allowing just two hits and issuing one walk. His fastball, once a prominent weapon in his arsenal, appeared lively and electric, often touching the mid-90s. Perhaps even more encouraging was his command. Allan consistently hit his spots, showcasing a refined slider and an impressive changeup that left opposing batters flailing at pitches outside the strike zone.
The Mets initially selected Allan in the third round of the 2019 draft, and while injuries have sidetracked his progress, his recent showing suggests he has not lost any prowess. His ability to handle the pressure and perform at a high level after being out of action for an extended period speaks volumes about his mental fortitude.
Mets management and fans alike are hopeful that Allan’s comeback will position him as a critical component of the pitching staff in the not-so-distant future. If he can maintain his health and continue to develop, Allan has the potential to become a cornerstone of the Mets’ rotation, bridging the gap between their current roster and a bright future.
Looking Ahead: Building Toward the Future
As the Mets season progresses, the organization’s focus on player development and scouting is becoming increasingly apparent. Young talents like Nolan McLean and the returning Matt Allan epitomize the commitment to creating a pipeline that can feed into the major league roster, fostering both immediate impact and long-term success.
With McLean’s impact at the plate and Allan’s resurgence on the mound, the Mets have reason to be optimistic. Their development programs are producing players who are not only capable of performing at the major league level but can do so with poise and impact.
In an era where roster depth and homegrown talent can significantly influence a team’s success, the Mets appear to be paving the way toward a competitive future.
