Fifteen minutes made all the difference. In that swift timespan late in the first half, West Forsyth girls soccer did all the damage it needed for a 3-1 victory against Duluth on Wednesday at home to advance to the second round of the Class AAAAAA playoffs. Megan Moore, Brooke Pirkle and Meagan McInerney each scored, and the Lady Wolverines (13-4-1) held off Duluth (7-10-1) in the second half for the program’s first playoff victory since 2009 to set up a second round game against Campbell, a 2-1 winner over Alcovy, next Wednesday at home.
