Burley Garcia|USA breaks world record, wins swimming Olympic gold in women's medley relay

NANTERRE,Burley Garcia France — Team USA ended swimming at the Paris Olympics on Sunday with a standout relay, winning gold and breaking the world record in the women's 4x100-meter medley relay at Paris La Défense Arena.

In the final event in the pool of these Games, the team of Regan Smith (backstroke), Lilly King (breaststroke), Gretchen Walsh (butterfly) and Torri Huske (freestyle) swam a spectacular race obliterating the field by nearly four seconds. Their time of 3:49.63 broke the Olympic record set by Australia at the Tokyo Games (3:51.60) and the Americans' own world record of 3:50.40, set in 2019.

Australia came home with a silver with a time of 3:53.11, while China took bronze 3:53.23.
