Liz Stillman’s goal with 5:30 left in sudden death overtime gave the Greenwich field hockey team a 2-1 win over top-seeded Wilton in the FCIAC semifinals on Tuesday in New Canaan.

The fourth-seeded Cardinals (11-4) earned co-FCIAC championship honors with Darien, which beat New Canaan, 3-0, in the other semifinal game.

It was the first loss of the season for Wilton, which dropped to 17-1.

"They knew they are a great team," Greenwich coach Ally Orrico said of her players. "It was just a matter of execution, and today was the culmination of all the hard practice and all the hard work. This was their best game. They executed the game plan perfectly."

Greenwich opened the scoring 13 minutes into the game on a goal by Sydney Cole, but Wilton tied things just a minute later off a penalty corner, when Madison Hendry’s blast was tipped into the cage by Valentina Tudisco.

The Warriors dominated the entire game, particularly in the second half when they had the Cardinals pinned in their own defensive end for nearly the entire 30 minutes.

However, Greenwich goalie Freddie Bancroft was sensational, finishing the game with 14 saves to earn MVP honors.

Wilton finished the game with a 15-0 advantage in penalty corners, and 15-2 advantage in shots at goal. Greenwich had possession inside Wilton’s arc only two times all game, and scored both times.

"They came out ready to play, and we did not," Wilton coach Deirdre Hynes said. "Greenwich played unbelievably tonight."
