Nearly 150 junior athletes from across the nation will compete this week for the 2013 USA Racquetball Wilson Junior Olympic Championships here. "Des Moines is becoming a real hot spot for junior racquetball," Iowa Racquetball Association President Bryan Crosser said. Scheduled Wednesday through Sunday at the Oakmoor Racquet and Fitness Center, 4731 Merle Hay Road, the tournament is junior racquetball's premier event. The tournament is a qualifier for the U.S. Junior National Team, which will compete in the International Racquetball Federation's World Racquetball Championships later in 2013.
