Romeo and Glynn will be the top threats for Harvard. Romeo leads the team with 24 goals on the season, while Glynn has a team-high 16 assists. The two players are tied for most points on the team with 35.

Still, the major key to the Crimson’s success on Wednesday will be the defense, led by co-captain goalie Kelly Weis, whose saving percentage of 50.3 percent is good for 12th best in the nation.

To pull the upset, Harvard will need its defense, ranked 17th in the country, to step up against a Boston College attack that is ranked 19th nationwide (the Eagles score an average 12.47 goals per game).

Junior defender Marina Burke and co-captain and fellow defender Tory Waldstein, who are tied for the team lead with 15 caused turnovers this season, will need to be major contributors in this effort.

“Our defense and goalie Kelly Weis have been playing incredible this season,” Glynn said. “We will need them to continue that tomorrow to secure a win."
