Trouble for the Crimson came in the third inning, as a big hit by Roesch sent home BU sophomore second baseman Erica Casacci and senior first baseman Rachel Hebert.

The Terriers stretched their lead to 4-0 due to a fielding error on a Tuthill pop-up that sent senior third baseman Rachel Moeller home.

“BU’s a good hitting team,” Allard said. “They scored a couple of runs, and we had some missed plays in the third inning that gave them a couple of runs too.”

The rivalry between BU and Harvard is a longstanding tradition, with the squads meeting twice a season each year.

“We have a great rapport with [BU],” Allard said. “They’re a good hitting ballclub; they’ve always had great pitching and good defense.”

Both the Terriers and the Crimson sit atop the standings in their respective conferences.

Harvard will take on Dartmouth this weekend in a doubleheader to decide the winner of the Ivy League North Division, and the team that will advance to the Ivy League Championship Series.

The Terriers lead the America East Conference, one game ahead of their next opponent, Maine.

“I think they’re a really solid club,” Allard said. “I’m glad that they’re our neighbors and we get to play them a lot, because they make us better.”
