GWANGJU, South Korea — Simone Manuel completed a sweep of the 50 and 100-meter freestyles at the world swimming championships on Sunday night, the first American woman to achieve the feat. Her haul during the eight-day event included four golds and six silvers.
She came back later to anchor the U.S. to an easy victory in the 4x100 medley relay. Regan Smith, Lilly King, Kelsi Dahlia and Manuel won in 3:50.40, lowering the mark of 3:51.55 set two years ago in Hungary.
Manuel outdid Australia’s Cate Campbell on the final leg, with the Americans winning by 3.
