Wintergreen Plaza is reinventing itself as a one-stop shopping center for sporting goods. TennisTopia is the latest addition to a lineup that already includes Total Hockey, Aardvark Swim & Sport, Capital Martial Arts, Gold’s Gym and Rockville Soccer. Darrell Haines, co-owner of TennisTopia, says he and wife Amy had been looking for a larger home on Rockville Pike after a decade at Congressional Village Shopping Center. “With the closing of Sports Authority and City Sports before that, we thought this was the right time to expand our business,” he says. “We liked the fact that Wintergreen Plaza is really becoming a mecca for sports.” It’s also becoming a mecca for post-sports meal breaks: The Habit Burger Grill and Jersey Mike’s Subs opened at Wintergreen this summer, and Wingstop is on the way.
