YORK – The York High field hockey team continued its quest for another Western Class B field hockey championship Saturday, defeating Greely 2-1 in overtime in the semifinals.

The top-ranked Wildcats (15-1), seeking a fourth straight regional title and seventh in eight years, will meet seventh-seeded Mountain Valley (11-4-2) in the final at 5:30 p.m. Tuesday at Thornton Academy in Saco.

Cari Posternak scored both goals for the Wildcats, including the overtime winner. It was the first real chance either team had in overtime in a game that had its share of near misses.

Posternak scored from the left side of the goal after receiving the ball on the baseline from Liz Fiorentino, who controlled the ball at midfield and was able to run it up the left side, fending off several defenders.

“I honestly have no idea what happened,” said Posternak. “The ball either went by her left pad or right through her legs. I just wanted to get a shot on. (Fiorentino) dribbled it up the field and made a cross. I scored (but) I don’t even remember.”

Fourth-seeded Greely (11-5) forced overtime by scoring on the last possession of regulation.

The Rangers were awarded a corner with 10 seconds left. The clock wound down but the Greely players took their time, knowing the game wouldn’t end as long as they kept the ball deep in York territory.

Greely didn’t score on its first chance but was awarded another corner. Eliza Porter passed from the baseline to Megan Labbey, who scored from just within the box.

York Coach Barb Marois said she wasn’t worried.

“I knew (the players) were kind of mad,” she said.

“I wasn’t concerned about a letdown. I just wanted to make sure the energy, or whatever they were feeling, was channeled in a positive way and wouldn’t distract them.”

Both teams had ample opportunities and dominated for stretches at a time.

York received 18 corners and had nine shots on goal; Greely had nine corners and 10 shots on goal.

Greely Coach Kristina Lane-Prescott thought her team was in control and could have scored more.

“We had plenty of opportunities to score. That’s always a Greely issue. I feel like we dominated. Unfortunately not taking that extra second to look up and shoot definitely hurt us,” said Lane- Prescott.

York also squandered corner after corner, often three or four in a row. But with 9:26 left in regulation, on its 16th corner, Posternak took the free pass from Shelby Spencer and took a shot that deflected off a defender and into the goal.

“Every year we always get to this point. York has beaten us the last couple years and they’re a strong team,” said Lane-Prescott.

“It was an amazing game, though, and I couldn’t ask for any more from my players.”
