It's Toccer!

The first racquet sport played on a field, Tennis Polo (Toccer) was created in 2004 in Bantam, Connecticut by a tennis instructor looking for a game to keep his tennis player occupied during one abnormally rainy summer. The sport had to incorporate the standard tennis equipment of a racquet and a ball, but otherwise needed to be unaffected by the elements.

After a variety of attempts at other games, Toccer immediately took a life of its own. It quickly became more than just a tennis diversion, but a sport of its own. That summer, they codified a set of rules and over the past five years, the sport has circled the globe and continued to expand its reach to a diverse set of players from 18 countries.
