There are nine clubs in the state and today more than 50 people came here to compete, one of them made history.
"This is my 10th year pitching and I've never even had a 90 percent, close to 100 percent so I was pretty happy with that," Ricky Hall says.
Today Ricky Hall became the first man in the state to pitch a perfect game.
"You've gotta put them on there-it's tough," Ricky says.
"If you think you're gonna do that you'll mess up and miss one-perfect games sneak up on you," Amy Hall says.
And Amy would know. Not only has she thrown a perfect game, she's also number two in the world.
"Practice and drive and knowing how to do it correctly, once you know what it takes to pitch a ringer and everything you have to do to make your shoe perfect then that's what you focus on and that's what you practice," Amy says.
No matter how well you play, you still have a shot.
"You get what you call a ringer percentage and that puts you in a class with people that pitch exactly like you do they don't have an advantage over you, but you don't have an advantage over them," Ricky says.
It's becoming more popular in the area, the Grottoes Horseshoe club's got a waiting list, but, watch out, it's competitive.
"I have a goal in life and it's to win the world title at least once it's the only thing I haven't done," Amy says.
Professional pitchers spend their weekends traveling all around the state to tournaments. Most of them say Grottoes is their favorite place to come. Grottoes hosts three to four tournaments a year.
