Last month’s inaugural Gladiator Polo match had thousands of attendees and apparently organizers are riding the momentum.

They’ve added six more games, secured more than 45 sponsors and created four teams that will be competing for $250,000 in prize money.

The title sponsor of the first season is the U.S. Polo Assn, whose CEO Brian Cummings called the new sport “hockey on horseback” in the news release announcing the expanded schedule.

Mark Bellissimo, CEO of Wellington Equestrian Partners and the creator of Gladiator Polo, planned to ease people into the sport this year with three events, but with the success of the first night, he’s adding the six-game tournament starting Thursday.
