For all of its tradition, the Mount Hebron girls’ lacrosse team thrived in the underdog role Wednesday night in the Maryland 3A/2A East final. The sixth-ranked Vikings — winners of a record 15 state titles — beat No. 2 Marriotts Ridge, 10-8, to earn their first state tournament appearance in three seasons and 20th overall.

Junior Haley Sutton finished with a team-high three goals, junior Samantha Brookhart shined at the draw circle and junior goalie Madison Fisher had 10 saves to hand the defending state champ Mustangs their first loss of the season. Mount Hebron advances to play Queen Anne’s on Friday night at Annapolis.

“It was not mistake-free by any means, but we were able to put together a full game,” Mount Hebron Coach Trish Sullivan said. “We are just extremely united as a team and peaking at the right time. [The win] was about Mount Hebron playing for Mount Hebron.”

Mount Hebron (15-2) had lost the past two region finals to its rival, including last season when Marriotts Ridge (17-1) avenged a regular-season defeat en route to its first state title. The Mustangs also won the regular-season meeting between the teams this year, 12-6, on April 17.

This time, the Vikings came with a plan and rarely wavered from it, staying patient to slow the pace against the explosive Mustangs. They scored the game’s first three goals and never trailed, earning a victory that keeps them in contention for their first state title since 2007.

“We did our homework, and we didn’t cut any corners,” Sullivan said. ‘We were doing as much as we could to prepare. We knew what we were facing and what to expect, and that only gives a team confidence.”
