Penn swept a doubleheader from Harvard on Sunday, winning the first contest, 27-6, before taking the nightcap, 6-2.
The Quakers collected 21 hits in the first contest, including four homers, with a pair coming from Craig Larsen.
Larsen finished the game 4-for-7 with five RBIs, while Cole Palis and Seth Werchan drove in four runs each. Jackson Appel chipped in with four hits, while Wyatt Henseler finished 3-for-3 with five runs scored to go along with two walks.
Penn scored seven runs in two separate innings and put up an eight-spot in the fourth.
Kevin Eaise secured the win in nightcap, surrendering just one run on four hits over six innings. Owen Coady secured his second save of the season, throwing four innings in relief while surrendering one run. He whiffed six.
Larsen went deep again in the second game, lofting a solo shot in the second inning.

The club is off until Wednesday when they travel to Piscataway for a non-conference game with Rutgers.
