Mills Godwin, boosted by a goal from Sarah Bellotti in the 51st minute, held off a furious counterattack after a lightning delay to defeat visiting Oakton-Vienna 1-0 in the quarterfinals of the VHSL Group AAA girls soccer tournament last night. Mills Godwin will face Cox of Virginia Beach, a 3-1 winner over Forest Park (Woodbridge), in the state semifinals Friday at 4 p.m. at Westfield High School in Chantilly.
