Riverdale Baptist second-year wrestling coach Sean Castorina, who had to draft students walking down the hall to form a team last year, may have finally earned respect from area teams. Led by the Young Guns (freshman twins Josh and Jeremy Young), Riverdale Baptist won the Model Classic Tournament Saturday at Gallaudet. The Crusaders finished with 191 points, 10 more than runner-up Gonzaga.

"This was the sixth tournament we've participated in and we've won two and placed very high in the other four," said Castorina, the youth director at the Riverdale Baptist Church. "We are 9-2 overall and one of those losses was to DeMatha {by 37-31}, one of the best programs in the area. I don't think we've gotten the respect we deserve but we're working on it. I know we're the youngest team in the area and we should be the team to beat in the future."

Josh Young is 23-4 at 103 pounds and Jeremy Young is 31-1 at 112. Also winning Saturday were Randy DeHaven at 145 and J.R. Proctor at 160, giving the Crusaders four champions out of seven finalists.

"We only took 10 wrestlers and all 10 made the final three," Castorina said. "We had a good tournament. Last year, we had to grab kids in the hall and talk them into wrestling. We had absolutely no one who had wrestled before. But we finished 10-4. This year, we have some fine wrestlers." . . .
