Walton and junior Jeanne Ficociello also had a strong showing for the Harvard defense.
"We weren't playing at our best but we were able to capitalize on their mistakes," said Walton.
Walton looks at their performance in a different light after playing No. 1 Maryland yesterday.
"[Maryland] played so flawlessly we weren't able to take advantage of any mistakes. We thought we were doing a good job covering cutters against Penn," said Walton. "But we realized today against Maryland that we aren't doing enough. We really need to communicate better."
With a total of eight saves, Donelan's solid goalkeeping was also critical for the Crimson. Throughout the season Donelan has performed consistently well in the cage for the Crimson.
"It was definitely a good win for us," said junior midfielder Kim Weeks. "An Ivy win is always a good win."
