“It’s just the greatest feeling,’’ said Costello, who has battled injuries (ankle and concussion) this season. “It’s like, we made history, that’s awesome.’’

The Minutemen (12-1-3) scored just three minutes into the game when a trailing Alison Boreiko one-timed a cross into the back of the Sachems’ net.

Winchester dominated possession in the second half but was unable to generate many scoring chances. The physical play of Lexington’s Nandi Mehta and Shelby Palafox bottled up center-mid Megan Hennessey. Mehta was issued a yellow card for her rough play on Hennessey late in the game.

“[Lexington] just did a good job preventing us from getting our crosses in, and when we got them in they were right at the near post and [Costello] was winning those balls,’’ said Winchester coach Chris Scanlon.

With 10 minutes remaining, Brooke Christopher broke free for the Sachems (10-3-3) and blasted a shot on Costello from just inside the box. Costello dove low and right to make the save.

“I wasn’t really thinking,’’ Costello said. “I just turned around and [Christopher] was shooting so I quickly dove to my right. It was all instinct.’’

Costello came through again with five minutes remaining, rising up to pull a corner kick out of the air.

“We know that any crosses that are in the air Cat is going to get,’’ said Lexington coach Frank Pagliuca. “You just can’t jump with her, with her vertical leap she can really get off the ground and go get them.

“We didn’t panic, we just defended and played organized and did what we needed to do to get the victory.’’

Pagliuca said he was proud of Lexington’s play this season.

“It’s a big accomplishment for these girls,’’ he said. “We play in a tough league and every game could go either way.’’
