The American women made history on night 1 of the 2019 FINA World Championships as the quartet of Mallory Comerford, Abbey Weitzeil, Kelsi Dahlia, and Simone Manuel took down the American Record en route to a silver medal. Comerford took the leadoff leg with a 52.98. Weitzeil then dove in to storm to the lead for the Americans with a 52.66.
The third leg went to Dahlia, who put up a 53.46. Canada and Australia took over the lead at that point, but the Americans were still in the hunt. Olympic champion Manuel took on the anchor leg in 51.92, which was enough to catch Canada and give the USA the silver behind the Aussies, who set a new Championship Record to win it.
