A group of local investors is negotiating with the American Professional Soccer League to buy the Salt Lake Sting, a Bountiful businessman said. Steve Maclyn, co-owner of the Scoreboard Sports retail soccer supply chain, said Monday that he and his partners are in discussions with the APSL, which took over the Salt Lake franchise from the nonprofit Sting Foundation last week."There's not a lot I can say at this point," he said. "We have a group and we're trying to finalize it, but it's not finalized yet. When it's put together, we'll be happy to talk about it." Macklyn said he is not part of the Merrill Osmond-led group that surfaced as a potential buyer last week. The league is committed to running the Sting only through Sunday's game at Colorado. The United states Soccer Federation announced last week that it has designated the APSL as it's official professional outdoor league as it prepares to host the 1994 World Cup. As a result, the APSL next season will require its franchises to upgrade capacity of their playing facilities and increase the size of their front office staffs. By 1994, the USSF wants a three-tiered pro league of first, second and third divisions in place. Whoever purchases the Sting would be faced with the cost of making the league-mandated improvements.
