SOUTH BERWICK — Marshwood continued its late-season surge as the fifth-seeded Hawks pulled away from No. 8 Windham for a 3-0 victory Saturday afternoon in a Western Class A field hockey semifinal.

In winning their eighth consecutive game — and third in the playoffs — the Hawks scored three goals in the second half, two by sophomore Emily Osborne, to break a scoreless tie. Marshwood (14-3) will play seventh-ranked Portland in the regional final at 7:30 p.m. Tuesday at Thornton Academy in Saco.

“The first half we were hesitant,” said Hawks Coach Lisa Truesdale. “We had jitters. There were a lot of fans there, we weren’t focused. At the half, I asked the girls, ‘What are we waiting for?’

“In the second half we started to play our game. And the first goal really amped us. The girls were relentless to the ball, they were the team I was used to seeing.”

Freshman Lindsey Poirier got the first goal, with 16:30 remaining in the second half.

One minute and 57 seconds later, another Poirier drive was tapped in at the left post by Osborne. Osborne then scored with 6:12 remaining, assisted by Karissa Boesch.

SACOPEE VALLEY 2, TRAIP ACADEMY 1: Paige Shortsleeves scored on the second round of penalty corners to lift the top-seeded Hawks (13-2-1) past the fifth-seeded Rangers (8-8) in a Western Class C semifinal at South Hiram.

Both teams scored in the first half, with Sacopee Valley getting the first goal, by Elizabeth Moulton 20 minutes in. But Traip responded about two minutes later, as Hayley Alessi scored.

The Hawks dominated, putting 24 shots on Traip goalie Emily Bolton, but could not beat her again until penalty corners.

On Sacopee Valley’s second round in the first set of three, Rachel Anderson gathered the ball just outside the circle and quickly hit it in, where Shortsleeves directed it inside the left post. Traip had one more chance, on its third round of corners, but committed a foul.

BELFAST 2, JOHN BAPST 1: Kristi Osgood scored using a reverse sweep with 1:58 left in regulation as third-seeded Belfast (12-1-3) defeated second-seeded John Bapst (13-3) at Bangor in an Eastern Class B semifinal.

Twin sister Kari Osgood and Maddy Cummings assisted on the winning play, which Osgood drove as the ball rolled away from her just above the penalty-stroke mark.

John Bapst took the lead with 4:56 left in the first half when Elise Tilton scored unassisted. Belfast tied it 20 seconds later when Ally James set up Kendra Kirby during a goal-front scramble.
