USA Wrestling has been notified that the arbitration claim, filed by Dennis Hall, concerning his championship series match at the U.S. Olympic Team Trials for Wrestling in Dallas, Texas, has been denied.      This is concerning Case Number 30 190 00444 00 in the matter of arbitration between Dennis Hall, claimant, and USA Wrestling, respondent. The decision was reached by arbitrator Herbert S. Channick on August 7, 2000.      Hall was defeated by Jim Gruenwald in the championship finals series at 58 kg/127.75 pounds at the U.S. Olympic Team Trials for Wrestling in Dallas, Texas, June 24, 2000, two matches to one.      In Dallas, Hall protested the third and final match, which was awarded to Gruenwald. The Protest Committee for the Olympic Team Trials upheld the decision, giving the victory to Gruenwald.      Hall, pursuant to USA Wrestling rules, appealed the Protest Committee's decision to USA Wrestling's Greco-Roman Sport Committee. That body agreed with the Protest Committee's decision on July 19, 2000, denying Hall's appeal.      Hall filed a Demand For Arbitration and named USA Wrestling, the U.S. Olympic Committee and Jim Gruenwald as respondents. The U.S. Olympic Committee and Gruenwald were dismissed from the case.      The Award of the Arbitrator provides that Jim Gruenwald is the representative at 58 kg/127.75 pounds in Greco-Roman wrestling on the U.S. Olympic Team.
