Gavin Buda’s first word was “ball.”

“True story,” the Harborfields dual-sport standout athlete said. “I’ve been playing sports as far back as I can remember.”

Baseball was his first love, he said, signing up for every team he could play on. He played for the varsity team from freshman through senior year of high school, also competing on high-level travel teams and tournaments in other states.

“It just seemed my path was set to play baseball in college,” he said.

But during his sophomore year, he decided to try out for the junior varsity football team with some of his friends. The team went undefeated, and the wide receiver was hooked.

“There was a feeling I got playing football that I never felt playing baseball,” he said. “This bond that is created between teammates that only happens in football. The knowing that you have each other’s backs — that feeling made me think if I work hard enough, this is the sport I’d like to play beyond high school.”

He never gave up on either sport, spending three days training for football and the other three for baseball. He said winters were intense, spending time indoors at batting cages while also gearing up for the fall football season, working with trainers like Jay Fulco, Mike Bouranis, Mike Feldman, James Brady and Jay Fiedler.

Buda this month became the first Suffolk County athlete to play in both the Rawlings Blue Chip Prospects Grand Slam Challenge and Empire Challenge football game, with Wantagh’s Ryan Sliwak achieved the feat in 2011. Buda said he had no idea the history he’d made at the time he was selected.

“From a young age you could tell the kid was super athletic — he stood out among his peers, and from there, he put in a ton of hard work to really hone that and continue to stay ahead of the pack,” said Harborfields baseball coach Casey Sturm, who coached Buda since he was in seventh grade. “He was a special player, and what really stood out at the end of his tenure wasn’t even so much what he did at the plate but his defense in the outfield and ability to pitch were huge.”

In Suffolk County’s 5-4 loss to Nassau June 8 at St. Joseph’s College, Buda tossed a baseball for what might be the last time. The pitcher and outfielder took over on the mound in the bottom of the fifth and retired the side in order.

“To end my high school baseball career being selected to play alongside players that were drafted to the MLB or heading off to colleges like Vanderbilt to play baseball is just awesome,” Buda said, although he joked if he let up a homerun he might not have been as happy. “To get on the mound and face those guys one last time was a great way to go out, and luckily, I did pretty good.”

A week later, he’d put down his glove and bat to strap on some football equipment.

In the Empire Challenge game, he made a 30-yard reception during a play he wasn’t even slated to be a part of. Knowing Northport quarterback Ryan Walsh, he said during the call in the huddle he told Walsh he could beat out the kid that was guarding him deep. Walsh trusted him, and Buda delivered. A step ahead of the defender, he said there was no way he was letting the ball drop.

His two-year head coach Rocco Colucci said for him personally the moment was fitting. Being a teacher at Northport he’d coached Walsh on the junior varsity level.

“This is why I coach football,” he said. “To see these guys grow and excel.”

He said too it was a privilege to watch Buda excel the way he did.

“Right off the bat I knew he was going to be a playmaker,” Colucci said. “His hard work showed. He was always looking to get better. He was very coachable — anything I told him to do, he’d do it. And because of that, [when other teams] put their best defensive players on him,  he’d still make the catch. He likes that type of best-on-best competitiveness in football, and there’s a lot of areas in football where he excels.”

Buda will be taking his talents to Hobart and William Smith Colleges to join the football team, but said he’ll never forget where he came from.

“Harborfields is a great school, but for some reason we are always under the radar in athletics — it’s a smaller school so I guess that’s why,” he said, adding that while other top athletes chose St. Anthony’s or Chaminade, he never questioned becoming a Tornado. “There were some great players that came through Harborfields before me, and there’ll be more after me. I just hope that I did my part to help put Harborfields sports on the map. The experience these last two weeks of playing in both all-star games is something I will carry with me forever.”
