Tom Shields, Lilly King, Kelsi Worrell and Michael Chadwick celebrate their gold medal in the 4x50-meter mixed relay at the 13th FINA World Swimming Championships (25m) at the WFCU Centre on Dec. 8, 2016 in Windsor, Ontario.


Team USA continued to collect hardware Thursday evening at the 13th FINA World Swimming Championships for short-course distances at the WFCU Centre in Windsor, Ontario, gathering two gold and two silver medals and rewriting a meet record while boosting its medal total to 13.

Leah Smith and Ashley Twichell gave the United States the top two steps of the podium in the women’s 800-meter freestyle in runaway fashion. Smith, a two-time medalist at the Rio 2016 Olympic Games, led from wire to wire to post a time of 8:10.17. Twichell, a 2011 world championships bronze medalist in the 5-kilometer open water, held second place virtually the entire race, touching at 8:11.95. Bronze medalist Kiah Melverton of Australia was 4.56 seconds behind Twichell in 8:16.51.

Tom Shields, a relay gold medalist in Rio, took silver in the men’s 100-meter butterfly with a time of 49.04 seconds, 0.96 behind South Africa’s Chad le Clos. It was the second time this week Shields took silver to the two-time Olympic medalist after placing second in Tuesday’s 200-meter butterfly final.

Shields joined Lilly King, Kelsi Worrell and Michael Chadwick to close out the evening with a championship record in the 4x50-meter mixed medley. Their time of 1:37.22 shaved 0.04 seconds off the old mark, set by Brazil two years ago in Doha, Qatar. The performance was only 0.05 seconds shy of the world record, written in 2013 by Team USA in Glasgow, Scotland. It was the second record relay performance in as many nights for Olympians King and Worrell, who were part of Wednesday’s world-record swim in the women’s 4x50-meter medley. Worrell boosted her Windsor winnings to four medals while King picked up her third podium finish.

The world championships continue through Sunday.
