FOXBOROUGH, Mass. — Freshman star Chloe Humphrey scored four goals and older sister Ashley Humphrey had four assists and North Carolina’s defense dominated as the Tar Heels capped an unbeaten season with a 12-8 win over Northwestern on Sunday for their fourth NCAA women’s lacrosse championship.

The top-seeded Tar Heels (22-0) and the second-seeded Wildcats (19-3) both matched their lowest scoring games of the season.

Madison Taylor, who set the NCAA record with 109 goals for Northwestern this season, was limited to four assists. Sam Smith and Lucy Munro each had two goals for the Wildcats in the loss.

Wildcat goalie Delaney Sweitzer set a new school record with 17 saves.

“It’s awesome. I’m so happy for my team,” North Carolina coach Jenny Levy said. “They played their hearts out all year. They’re warriors, they’re dogs. Congrats to Northwestern … they’re great competitors and obviously make us better because of what we had to do to beat them.”

Levy’s freshman daughter Kate scored the goal that put the Tar Heels ahead to stay at 2-1. They became the first mother-daughter combination to win the championship.

Northwestern, the 2023 champion, dropped to 8-3 in championship games. The Wildcats had advanced to the title game with a comeback victory over Boston College in Friday’s semifinal. They were playing in their sixth consecutive Final Four and 16th in the last 21 years under coach Kelly Amonte Hiller

The game drew a record crowd of 14,423 to Gillette Stadium as part of a Final Four weekend that includes the men. Top-seeded Cornell faces second-seeded Maryland in the men’s final on Monday.

Ashley Humphrey finished with 90 assists as the NCAA career leader broke her single-season record. Chloe Humphrey pushed her NCAA freshman record to 90 goals.

“I have no words. It’s unbelievable,” Ashley Humphrey said. “To be able to do it alongside my sisters is something I could never have dreamed.”

Ashley Humphrey spent her first two seasons at Stanford while her sister Nichole, finishing up her career as a reserve, was on North Carolina’s 2022 championship team.

North Carolina led 7-4 entering the fourth quarter, then got three goals in less than a minute, including two from Eliza Osburn that were nine seconds apart.

Betty Nelson had eight saves for the Tar Heels.

The Wildcats are scheduled to host the 2026 Final Four at Northwestern Medicine Field at Martin Stadium.

The school earned its 12th national title earlier in the week when the women’s golf team won its first NCAA championship over Stanford.
