Mets Prospect Notes: Nolan McLean shines in season debut, Matt Allan's strong return

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 ...
