SwimMAC's Kathleen Baker, Caitlin Casazza, Elsa Welshofer and Nora McCullagh threw down a 1:40.82 to not only win the finale, it also lowered the meet record in the event. McCullagh had a dominant anchor leg with a 22.63 to close out the win. That performance downed the previous meet record of 1:41.63 set by Saint Andrew's just a year ago. The 15-16 squad neared the U.S. National Age Group record of 1:39.63 clocked by the Aquajets with Olympian Rachel Bootsma in 2009.
