Laurie Calloway, head coach and general manager of the Salt Lake Sting, will become coach of the San Francisco Bay Blackhawks, the Sting announced Thursday.

"This was a tough decision for me to make," said Calloway. "I helped bring professional soccer to the Salt Lake area. The fans' support of myself and my players will always be appreciated. The state of Utah really got behind us."Calloway said that with local ownership of the Sting still a question mark, he felt he had no choice but to accept the position with the Blackhawks.
