BOSTON (Interstat) — Benjamin Moulin pitched five no-hit innings and the Penn Quakers held off a furious Harvard Crimson rally in the ninth inning to secure a 7-6 victory Sunday afternoon at Joseph J. O’Donnell Field.

Penn improved to 17-18 overall and 9-6 in the Ivy League, completing a three-game sweep of Harvard. The Crimson fell to 8-25 and 3-9.

Moulin, the top star for the Quakers, struck out six and allowed no hits and no earned runs over five innings. He retired the first 11 batters he faced before issuing a walk in the second inning, but Harvard never threatened against him. Moulin’s outing was a sharp turnaround from his previous three relief appearances, in which he had allowed one earned run over 4⅔ innings.

Penn scored three runs in the first inning and three more in the fourth to build a 6-0 lead. In the first, Taylor singled, advanced on a fielding error by the right fielder and scored on a single by Gavin Degnan. Degnan stole second, and Secretarski scored on a groundout by Spaventa. Pokrovsky added an RBI single to cap the frame.

The Quakers added to their lead in the fourth. Collins doubled, Echevarria walked and O’Brien singled in Collins. Later, Degnan laced a two-run single up the middle, making it 6-0. An RBI groundout by O’Brien in the second inning had given Penn an earlier 1-0 advantage.

Harvard starter Luca Alagheband entered in the fourth and limited the damage, allowing one hit and no earned runs over 4⅓ innings while striking out four.

Penn extended its lead to 7-0 in the eighth on an RBI groundout by Guachione, who had doubled.

Harvard began its comeback in the bottom of the eighth. Colasante doubled, moved to third on a walk and scored on a wild pitch, cutting the lead to 7-1.

The Crimson mounted a dramatic rally in the ninth. Wilson singled, Rickheim singled and Kang walked to load the bases with no outs. After an infield fly, Lane singled to score Wilson. Shulman, pinch hitting, then laced a two-run single to center, bringing Harvard within 7-4. Smith doubled down the third-base line, scoring Lane to make it 7-5. Khozozian grounded out to third, scoring pinch runner Colasante, and the Crimson pulled within 7-6. But Stone grounded out to third to end the game.

Harvard outhit Penn 11-10, but stranded eight runners. Jack Rickheim led the Crimson with four hits in five at-bats. Josh Katz earned the win in relief for Penn, pitching two innings with three strikeouts. Nicholas Newburn recorded the final two outs for the save.

Penn also got two hits and three RBIs from Degnan. O’Brien drove in one run.

The game was played under overcast skies in the afternoon. Interstat’s game simulator had projected a final score of Penn 6, Harvard 2, and its ELO system gave Penn a 58.70 percent probability of winning.
