Two big victories over the weekend have left the Amherst women’s swimming and diving team full of confidence heading into the NESCAC Championships. The winning run started Saturday when the Mammoths upended No. 8 Massachusetts Institute of Technology and included a home victory over Springfield College on Sunday.

Going into Saturday’s meet against the Engineers, the No. 10 Mammoths were the underdogs. It didn’t take long for Amherst to set the tone, however, as the team of Stephanie Moriarty ’18, Katie Smith ’19, Geralyn Lam ’18 and Ingrid Shu ’20 won the first event of the day, the 200-yard medley relay, while the team of Bridgitte Kwong ’19, Nina Fitzgerald ’21, Tracy Chen ’20 and Natalie Rumpelt ’20 took third.

An impressive performance in the 200-yard freestyle saw Rumpelt take the top spot with a time of 1:53.95, and classmate Sarah McDonald finished third with a time of 1:56.13. In the 100-yard backstroke, Amherst claimed first and second with strong showings from Moriarty and Kwong, respectively.

In the one-meter diving event, Lindsey Ruderman ’21 continued her dominant rookie season, posting a score of 290.54 to score nine points for the Mammoths.

In the 500-yard freestyle, Livia Domenig ’19 won the event with a time of 5:09.42, with fellow Mammoth Jayne Vogelzang ’19 placing third. These strong performances added up to a 171.5 to 128.5 upset victory for Amherst.

The Mammoths returned on Sunday to host Springfield on senior day at Pratt Pool, and the hosts made sure the home crowd left happy. Moriarty, Fitzgerald, Lam and Rumpelt broke the pool record by finishing the 400-yard medley relay in a blistering time of 3:53.90, smashing the old record by nearly four seconds. In the same event, Tracy Chen ’20, Smith, Sarah Wang ’20 and Dorit Song ’19 raced their way to a third-place finish with a time of 4:09.61. The second race of the day yielded yet another new pool record, as Kwong swam her way into the record books with a win in the 400-yard individual medley in a time of 4:32.16. Sophomore Heather Grotzinger finished right behind her teammate to claim second in 4:36.87. Amherst clinched its win by sweeping the top-three spots in the 50-yard backstroke (Moriarty, Chen and Ingrid Wefing ’21), the 100-yard butterfly (Clare Leonard ’19, Julia Ruggiero ’21 and Meredith King ’21) and the 50-yard freestyle (Lam, Rumpelt and McDonald). In the one-meter diving, both Ruderman and Jackie Palermo ’19 crossed the NCAA B-cut threshold of 255.00 points with scores of 292.87 and 262.42, respectively.

In the final event of the day, Shu, Rumpelt, Moriarty and Lam swam the 200-yard freestyle relay in 1:36.10, a time that doubled as both a pool record and a fitting end to senior day with Lam swimming the last leg in a 172-110 Mammoth victory.

With the pair of wins, Amherst finished its regular season with a sterling 7-1 record. The Mammoths will have two weeks off before traveling to Williamstown, Massachusetts for their biggest meet of the year so far: the NESCAC Championship, a three-day event that starts Friday, Feb. 16.
