The high-scoring Gophers women’s hockey team got only one goal from its top three lines — an empty-netter in the final minute — but it still got enough offense to beat Yale 3-1 on Saturday afternoon to sweep their nonconference series. Minnesota won the opener 7-1.

“It was kind of a workmanlike effort for us tonight,” Gophers coach Brad Frost said. “We played well, but obviously it was close right there until the end. Our team did a really good job finding a way and getting a sweep on the road.”

Fourth-line wings Abigail Boreen and Kippin Keller scored goals in the first period to give No. 2 Minnesota (15-2-1), which has won eight games in a row, a 2-0 lead. The goal for Boreen, a freshman from Hill-Murray, was her second this season. Keller’s goal at 16 minutes, 26 seconds was her first this season — and fourth of her career — and proved to be the winner. Keller, a junior from Minnetonka High School, had a game-high seven shots on net.

Catie Skaja, the center of that fourth line, had assists on both goals.

Tabea Botthof scored for the Bulldogs (2-10) at 4:37 of the third to cut the Gophers’ lead to 2-1.

Grace Zumwinkle, who had a hat trick in Friday, dispelled most of the tension with an unassisted insurance goal with 54 seconds left. It was her team-high 12th goal of the season.

Alex Gulstene had 12 saves for Minnesota, Tera Hofmann 41 for Yale.

“Credit to Yale,” Frost said. “We knew they were going to come out better than they did yesterday. They’re a well-coached team, and they did a great job.”
