If you have a child who loves to play baseball, put the New York Sluggers on your radar. Started by a great local coach with a professional baseball background, Fabricio Benitez, and a New York Mets pitcher, Frank Francisco, the Sluggers opened one of the city’s best indoor batting cages (and pitching tunnels) last January. The space offers baseball training to individual players as well as to school teams. And now the Sluggers are expanding to include youth travel baseball teams of their own—with a home base on Randall’s Island for children ages 9 and up.
