Co-captain Reed Endresen picked up his third win at the No. 2 spot for the Crimson, defeating Quaker Danny Greenberg in four sets.

The first set finished in favor of Penn, but Endresen was able to outlast his opponent. This was especially evident in the third set—a 16-14 battle for the 2-1 advantage in games.

“Fitness was a key element in helping us win,” Hill said. “It also took mental strength to be able to handle the pressure of the crowd and the opponents. That really carried us through in the end.”

Outstanding performances for Harvard came from everywhere in the lineup, with freshman Thomas Mullaney and sophomore Alexander Ma picking up dominant victories in straight sets. Hill and freshman Brandon McLaughlin defeated their respective opponents in tough five-game matches.

Harvard’s one loss came at the No. 9 spot, as Penn’s Justin Ang defeated Crimson junior William Ahmed in four sets. The match included an 11-9 victory in the first set and two other games decided by just two points.

Overall, this weekend marked one of the season’s biggest tests yet for the Crimson, which has just two more regular season matches left to play. For the rest of the season, fitness appears to be one of Harvard’s main focuses.

“We’ve been doing a lot of fitness, about three times a week,” Power said. “Our bodies will definitely be well prepared for our [upcoming] matches.”
