OLD TOWN, Maine — Last season, McKenna Smith of Old Town High School outdueled Oceanside of Rockland’s Chloe Jones in an eight-inning Class B North softball final. But Saturday belonged to Jones. The junior right-hander allowed just two hits and she also drove in what proved to be the winning run with a single in a three-run, sixth-inning rally as the Mariners bested Smith and the Coyotes 3-0 in their Class B North semifinal. Third seed Oceanside (17-2) takes on top seed Brewer (18-0) in Wednesday’s 3 p.m.
