JD Beach dominated the first day of the Ethan Gillim Memorial inside the Southern Illinois Center at the Du Quoin State Fairgrounds. Beach, a 19-year-old Washington State native now living in Philpot, Ky., won five of the six pro races his entered on his Red Bull-backed Honda CR450F. Only a victory by Attica, New York’s James Rispoli, in the Open Pro/Am TT final kept Beach from earning a complete sweep of Saturday’s pro races.
