Dodge, duck, dip, dive and dodge -- the five D's of dodgeball, according to Patches O'Houlihan, the legendary hurler from Dodgeball: A True Underdog Story.

On Sept. 10, West Michigan throwers might consider O'Houlihan's advice as teams converge on The B.O.B parking lot, 20 Monroe Ave. NW, Grand Rapids, for an aerial assault of red rubber balls.

Teams of six players 21 years of age or older will try to mercilessly pelt and eliminate their opponents in the 2011 WGRD Dodgeball Challenge, which is sponsored by 97.9 WGRD. Each team will play one another in the round-robin style tournament until one overall winner is determined. The winning team will receive a prize pack valued at more than $500, which includes gift cards from The B.O.B. and Leinenkugel's swag.

The tournament will host a maximum of 60 co-ed teams, but Dave Kim, Promotions Director for WGRD, said that 20-40 teams is more realistic.

Participants can register their teams at WGRD.com until Monday, Sept. 5. The registration fee is $120 per team. The first game will start at 10 a.m. on Saturday, September 10. Spectators can watch the competition for free.

At first glance, dodgeball might not seem like a very complicated sport. It's basic human nature to avoid projectiles sailing toward your face. President Bush showed us this at a 2008 press conference when he skillfully dodged a one-two combo of angry Iraqi wingtips.

But there's more to dodgeball than just not getting hit -- teams need offensive strategies, explained Paul Hillebrand, a competitor in this year's tournament.

"There are times when you need to coordinate with your teammates to throw at the same person," said the former member of Grand Valley State University's dodgeball team. "For example, one guy throws high, and the other throws low, or they each throw from different angles."

With $500 worth of prizes on the line, Hillebrand expects a day of fiercely competitive and entertaining dodgeball.

"You don't have non willing combatants in competitive dodgeball," he said. "You don't have that kid who gets clocked in the face and doesn't want to be there. Everyone wants to be there, so you can go all out and not feel bad about hitting people in the face."
