The match came down to the No. 7 spot, where Princeton senior Alex Sawin was able to win a pair of hard-fought early games against Lillian Fast 12-10 and 11-8. Fast took the third 11-9 and used that momentum to grab wins of 11-6 and 11-7.
That completed a final-shift sweep for Yale, which also got wins from former national champion Millie Tomlinson at the No. 1 spot, as well as a 3-1 win for Issey Norman-Ross at No. 4.
Princeton, which fell 5-4 to Yale during the regular season as well, got out to an early lead after impressive performances by the junior duo of Nicole Bunyan and Hallie Dewey. Bunyan took out Shihui Mao for the second time this season by a 3-0 score, while Dewey remained perfect against Ivy League competition with a 3-0 win at the No. 6 spot.
Yale fought off the early sweep with a comeback win at the No. 9 spot, but Princeton got back on the board with a 3-1 win at No. 5. That opened the door for a heroic performance by senior co-captain Libby Eyre, who has battled injuries throughout the season. In her best performance of the year, she defeated Kimberley Hay 11-9 in the fifth for a 3-2 win at the No. 2 spot.
Princeton will move to the consolation round Saturday morning and will take on eighth-seeded Dartmouth.
