Grace Ramsdell completed a three-point play with 2:08 remaining to break a tie, and top-seeded Wells survived an upset bid, defeating ninth-seeded Maranacook 37-30 in a Class B South girls’ basketball quarterfinal Saturday at the Portland Expo.

Wells (18-1) scored the final nine points after the Black Bears led 30-28 with five minutes left.

Ramsdell, a 1,000-point career scorer, finished with eight to go with seven rebounds as Maranacook (9-10) clogged the middle.

After Ramsdell’s three-point play, Grace Boucher hit both ends of a 1-and-1 with 50 seconds left, then two more free throws with 21 seconds to play.

Maranacook trailed by four points at the half and one point through three quarters behind the inside work of Allie LaBelle and the outside play of Eliza Pattershall. They each finished with nine points.

Boucher had 10 to lead Wells, which hit 3 of 23 3-pointers.

“That’s the tournament for you,” said Wells Coach Don Abbott. “The game was played more at their pace then we probably wanted, but the girls were resilient and found enough plays to win.”

“I told the girls after, ‘Don’t listen to the narrative that we had a difficult time.’ We’ve lived by the same mantra all year: Win any way you can.”

The Warriors will meet York (11-5) at 2:45 p.m. Tuesday in the semifinals at the Expo.
