Bailey Oliver scored twice, including the go-ahead goal off a rebound with 16:58 remaining, as the top-seeded Wildcats (11-3-1) fended off the eighth-seeded Clippers (7-8) in a Class B South quarterfinal in York.

Emlyn Patry assisted on Oliver’s first goal about three minutes into the second half. Yarmouth tied it less than two minutes later on a goal from Lydia Guay.

York advances to play fourth-seeded Lake Region in the semifinals on Saturday.
