The foundation began working with Eagle Academy students in September 2015. The learning center was still under construction, so the classes met at the Harlem Y.M.C.A. The boys swung plastic clubs until the center opened eight months later.

“As soon as we put a real club in their hands, they wanted to swing it,” said Brian Hwang, one of the foundation’s two full-time teaching pros. “And then they started to hit their first shots into the screens. That was it — they loved it.”

As the only boys’ high school golf team in Harlem, one composed entirely of freshmen, Eagle Academy lost every match last spring. Still, the boys said they gained valuable experience. The season produced highs as well as lows.

“Look at this shot!” Randy Taylor, the foundation’s other full-time pro, said during the Bronx Science match last spring as a drive of Antonio’s flew toward the green at Mosholu’s third hole, stopping 10 feet from the cup.

Mr. Taylor, 35, grew up in a family of modest means in Bridgeport, Conn., and took up the game at the insistence of his mother, who enrolled him in an after-school program that combined golf and academics. When he was 14, Mr. Taylor met Tiger Woods, then a rising star, who awarded him a scholarship to a Nike golf camp.

“I tell the boys all the time,” said Mr. Taylor, “that changed a lot for me and put me in a situation where I could learn this game of golf, be good at it and teach it for a living, and pass it on to them.”
