Annual net revenue at athletic supplies cataloger Sport Supply Group (OTC BB: SSPY.OB) decreased 8% , to $103.6 million for the fiscal year ended March 29. The Dallas-based marketer, which sells to schools and recreation leagues, attributes the decrease to the economic slowdown, reduced participation in traditional youth sports, and a reduced sales force. There was good news, however, as the company narrowed its loss by 37%, to $3.6 million from $5.6 million the previous year.
