Andrew Cheever scored on a wild pitch in the bottom of the seventh inning and earned the victory in relief as No. 2 Yarmouth rallied to beat 10th-seeded Leavitt, 2-1, in a Class B South baseball quarterfinal Thursday afternoon in Yarmouth.

Yarmouth (12-5) will host sixth-seeded Greely in Saturday’s semifinal round.

Clippers starter Liam Hickey and Leavitt starter Will Keach matched zeroes for five innings, before Leavitt (9-9) took the lead in the top of the sixth when Keach scored on a throwing error.

In the bottom half, Jack Janczuk hit a sacrifice fly to drive home Jonny Cody.

After stranding the potential go-ahead run at third in the top of the seventh, Cheever drew a walk from reliever Colton Taylor in the bottom of the seventh. He stole second and went to third on a flyout, then raced home on a pitch in the dirt that got away.

Keach had two hits for the Hornets.
