ITHACA, N.Y. – No. 19 Penn scored four unanswered goals midway through the fourth quarter to take its first lead of the game, and then got the game-winner with 17 seconds to play as the Quakers upset No. 8 Cornell men's lacrosse, 16-15, this afternoon at Schoellkof Field. "It's a disappointing loss for an important game in the Ivy League standings," said Peter Milliman, the Richard M. Moran Head Coach of Lacrosse. "We did what I would anticipate we needed to do to win, but we didn't make the plays when they mattered most. And that's the difference to the game. When the most important plays were needed we didn't make them and Penn did. They're good. They played hard. They've got a great senior class. Their leadership is excellent and they're well coached. They were making plays when they needed to and we were not." It was the first time this season Cornell surrendered a lead in a loss, as the Big Red had taken a 7-2 advantage just under five minute into the second quarter before an unreleasable one-minute penalty, coupled with an additional 30-second penalty put Cornell down two men, allowed Penn to get back into the contest with three consecutive man-up goals. "I think our defensive struggles came from undisciplined penalties," said Milliman". We were on man-down a lot. They also came from failed clears, at the worst times. So we were giving second chance opportunities to them. And realistically there were transition and scramble opportunities after loose balls." Cornell eventually pushed its lead back to four goals (11-7) with back-to-back tallies from Connor Fletcher and Johnathan Donville late in the third quarter, but Penn closed the stanza with a pair of scores to steal back some of the home team's momentum. The teams traded goals to start the fourth before another man-up goal from Penn opened up the 4-0 run to give the visitors a 14-13 lead with 4:42 to play. Luca Tria won the restart and John Piatelli knotted the game at 14-14. After another Quaker goal, Piatelli would score his fourth, and the Big Red's final, goal of the game to tie the contest at 15-15 with 2:02 remaining on the clock. In addition to his four goals, Piatelli added one assist for his seventh game of the season with at least five points. Jeff Teat led the Big Red with three goals and three assists, while Donville chipped in two scores and one assists. Jake McCulloch also had two goals, while Clarke Petterson extended his point-scoring streak to 22-striaght games with one goal and one assist. Defensively, Cornell caused 10 of Penn's 20 miscues, led by Brandon Salvatore's five caused turnovers on the day, a mark good for fourth in Big Red history for caused turnovers in a single game. Salvatore also picked up a career-high 14 ground balls. In goal, Chayse Ierlan made 15 saves. Penn (4-3, 2-0 Ivy) was led by Tyler Dunn (five goals, one assist), Adam Goldner (four goals, one assist) and Sam Handley (three goals, two assists). In goal, Reed Junkin made seven saves. The Quakers won 20-of-33 face-offs, with Kyle Gallagher winning 20-of-32, and had the advantage in shots (46-29). Cornell had the edge in ground balls (41-28) and forced the visitors into a 13-of-20 performance on clears. Still, the Big Red finished with one more turnover (21-20). Both team's man-ups were solid, with Penn going 4-of-5 and Cornell scoring on 2-of-3 chances. Cornell (5-4, 0-2 Ivy) is back in action next weekend when it welcomes Dartmouth to Schoellkopf Field for a 1 p.m. contest on Saturday, April 30.
