Fairfax County Supervisor Robert B. Dix Jr. (R-Hunter Mill), who was defeated in his reelection bid in November, will become an executive with an Internet company that runs a Web-based clearinghouse for youth sports information.

Dix, a longtime youth basketball and football coach, will quit his part-time job as an aide to the House subcommittee on the District chaired by Rep. Thomas M. Davis III (R-Va.), a position that critics said created a conflict of interest. His new job, as a senior vice president at SportsCombine.com will start immediately.

"I believe this is a company that will grow and grow rapidly," Dix said yesterday. "It allows me to utilize my business skills and combine that with my passion for youth sports. It's a concept that we have a great opportunity to take nationally."

Dix has spent the last eight years representing the Reston and Vienna areas on the Board of Supervisors. A sometimes controversial figure who was known for his temper, Dix nonetheless had the support of many of the high-technology business executives whose companies have located in his district.

Last year, those executives and others contributed more than $200,000 to Dix's losing campaign. Dix lost to Democrat Catherine M. Hudgins, a Reston activist and former aide to Board of Supervisors Chairman Katherine K. Hanley (D).

Despite his recent loss, Dix said his experience as an elected official will serve him well in his new job.

"Certainly, the network of contacts both in the political arena and the business arena will be an asset as we try and grow this company," Dix said. "The opportunity to have kids get exposure is going to help revolutionize the way college recruitment works."

SportsCombine.com, based in Vienna, allows youth and school sports teams to report statistics and scores on individually designed Web pages. The company focuses mostly on Washington area teams, but Dix and Chief Executive Officer Casey Samson said the plan is to expand to metropolitan areas across the country.

"Fairfax County was our test market," Samson said. "We have a working prototype that's expanding dramatically. We felt Bob could really help us along."

Dix said he hopes to focus on helping inner-city high school athletes get more exposure by making it easier for college recruiters to find out about them through the SportsCombine Web site.

Hanley, a longtime Dix adversary, said she wishes him well in his new endeavor.

"It sounds interesting," she said. "It's certainly something Bob knows a great deal about. It could well be a perfect fit. I offer my congratulations on an exciting opportunity."
