They scored the goal without senior Gianna Antone, who was penalized for 10 minutes with 9:01 remaining in the game.
The senior standout had scored the Sailors first goal in the opening half with 9:45 left until intermission.That had evened the score after Severn’s Hailey Schendel had scored off an assist by Regan King giving the Admirals a 1-0 lead.
The Sailors pressure the visitors in the second half with strong midfield play from Antone, Logan Dean and Lindsay Kelly, setting up penalty corners by insert Madison Capps.
But two shots by Antone leaked wide and shots by Hope Keller and Lacey were saved by goalie Arielle Hillock.
But on the third penalty corner in the final four minutes, Lacey converted.
“One of the biggest things I’ve tried to instill this year is team cohesion and accountability,” first-year varsity coach XiaoYing Van Schaik said. “The one thing that amazes me is that all of our girls stepped up.”
The victory improved the Sailors to 8-1 in the conference and 8-5 overall.
It was the fourth straight win, including a 1-0 decision over St. Mary’s, who was previously unbeaten in the conference.
St. Mary’s is 7-1 and in second place and Severn is third at 5-3.
“We were major underdogs (before the season) and I think we are starting to make our mark and have a comeback,” coach Ying said.
Mount de Sales seniors, who were honored after the game, included Caroline Corbitt, Rileigh Byrd, Rachel Hornig, Libby Rehkemper, Antone, Capps, Kelly, goalie Heather Stofregen and managers Carly Carruba and Grace Laquarta.
