BREWER, Maine — Libby Hewes struck out three hitters in Brewer High School’s 6-2 victory over Oceanside of Rockland/Thomason in Wednesday’s Class B North softball final at Doyle Field in Brewer. But she didn’t have to. As usual, the Brewer High defense was superb, turning in an errorless performance to back the junior righty. The 19-0 Witches will hope that trend continues when they host Greely High of Cumberland Center, 13-7, in the Class B state championship at 4 p.m.
