The fastest fastball in the Mets' organization is coming to New York City.

The Mets promoted Raimon Gomez to the Brooklyn Cyclones, their High-A affiliate, on Monday. The 23-year-old righthander is best known for throwing extremely hard, including recently reaching 104.5 mph with his heater in his first month of action after a nearly two-year, injury-induced layoff.

Gomez had a 0.69 ERA in six appearances with Low-A St. Lucie, collecting 20 strikeouts in 13 innings.

With that taste, Gomez made more tangible what had excited Mets officials in a more hypothetical way during spring training. He is finally healthy — following a lengthy recovery from Tommy John surgery early in the 2023 season — and still throwing hard.

“He’s a high-octane arm who has the capacity to do a lot of pretty special things with the baseball,” Andy Green, Mets senior vice president of player development, said in an interview. “Any satisfaction you feel in [Gomez’s recent results] is built around the work he’s put in to get back to that spot and the rehab group that worked insanely hard with him to get him to that spot. It’s gratifying for those [reasons].

“There’s a long way ahead of him to get to where he ultimately has to go and there’s a lot of work in front of him. But there’s a lot of really encouraging things to take out of the first month of the season and now it’s just repping it out and continuing to improve in every facet.

“If you put in the work and you have that skill set, good things are going to happen. When you hear things about [Gomez] continuously improving and the work ethic, that’s exciting.”

The next step for Gomez is a typical one for inexperienced pitchers: Throw more strikes. He issued 10 walks in his 13 innings in St. Lucie.

As Green said: “If you want to pitch for us in the big leagues, it’s stuff and strikes.” Gomez has the “stuff,” the velocity and movement and other characteristics that make his pitches hard to hit. If he has strikes, too, he can continue to move up quickly.

“It’s top-end stuff,” Green said.

For now, Gomez is working as what Green called a “bulk reliever,” a workload similar to what Max Kranick and Huascar Brazoban have done for the major-league team (albeit in a more scripted and controlled way in the minors). The Mets haven’t determined his possible eventual big-league role, starter or reliever, but want him to pitch more frequently than once every five or six days for the sake of building up an innings total in shorter spurts.

“We have the belief that he can start. We also have the belief that he can be very valuable out of the ‘pen,” Green said. “And coming off of the injury, kind of the bulk reliever-type innings make the most sense for him this year. Leave multiple avenues open for the future and get him as many reps on the mound as possible.”

Also among the slew of interesting pitchers promoted on Monday: righthander Dylan Ross, who joined Double-A Binghamton, the level at which dreaming about the majors starts to feel more real and practical.

Ross, 24, has barely pitched professionally since the Mets drafted him in 2022 (13th round) because of two Tommy John surgeries. But now he is throwing 101 mph. With Brooklyn, he struck out 23 batters in 11 2/3 innings to pair with a 1.54 ERA in a more traditional reliever schedule.

“He throws gas,” said Mets director of player development Andrew Christie.

Green said: “I’m not one to highlight velo immediately, because it’s so much more than velo, but he’s been in the 101 category himself this year. He’s got feel for his split and a couple of real spin weapons.”

And then there is Matt Allan, a high-profile third-round draft pick in 2019 who hadn’t pitched since that year because of a variety of issues, including two Tommy John surgeries. He, too, is joining Brooklyn. With St. Lucie, he had a 3.60 ERA in seven starts (15 innings) and a fastball in the 95-97 mph range.

That his comeback has taken him even this far is remarkable.

“It’s exciting for all of us, understanding how much work he’s put in and how many people have worked alongside him just to get him on the mound consistently again,” Green said. “He’s shown some exciting flashes at times and he’s shown some rust at times and I think we anticipated both of those things.”

Before their series opener with the Pirates, the Mets hosted a family reunion of sorts between a pair of distant relatives: Pittsburgh shortstop Isiah Kiner-Falefa and Scott Kiner, son of Ralph Kiner, the late Hall of Famer and longtime Mets broadcaster.

Kiner-Falefa’s great-great-great-grandmother is Ralph’s great-grandmother, according to Scott, who is something of a genealogist. Kiner-Falefa said he grew up hearing stories about their connection — and was obsessed with the 1940s-50s Pirates slugger since he was 8 years old — but had never known anybody from that branch of the family tree.

“I’ve always talked about it and my grandpa has always talked about it. But for me to not meet anybody on my grandfather’s side, it felt like something was missing,” said Kiner-Falefa, who is from Hawaii. “To finally meet Scott, it’s all full circle. I’m getting a little emotional right now. This is incredible. This is an incredible moment that I never thought would happen.”

Scott Kiner said: “There is Pennsylvania Dutch in this guy. Not much, but he is Pennsylvania Dutch.”
