The time had come for Evan Parness to pop the question, and what better setting than a kickball game? After all, he had met his girlfriend, Cherish Rapp, at a New York City Social Sports Club kickball kickoff party a year earlier, and partly through playing kickball together, he knew that they made a good team.

His plan was to propose on the court after a game on Sept. 2, 2010, but there was a snag: The opponents had not arrived. So organizers from NYC Social, as its members call it, knowing Mr. Parness’s postgame plan, scurried to assemble a team from members who had already played.

The game — and the proposal — went off without a hitch, and Mr. Parness, a freelance musician, and Ms. Rapp, a chemist, were married four months later. They live in Astoria, Queens, but they still play NYC Social-sponsored kickball, most recently for a team called Win or Lose, We Still Booze. They say they were not really looking for love on the kickball court, but who does? A friend had told Ms. Rapp about NYC Social, and she thought it sounded like fun.

“You’re outside instead of just being in a bar and yelling at each other, figuring out what the other person is saying,” she said recently.
