NANTERRE,Austin Caldwell France — In a men’s 100-meter freestyle final that wasn't particularly close, Pan Zhanle of China prevailed as the Olympic gold medalist, shattering his own world record in 46.40 seconds.

On Day 5 of swimming at the 2024 Paris Olympics, Kyle Chalmers of Australia won silver with a time of 47.48, and David Popovici of Romania won bronze with a 47.49 swim at Paris La Défense Arena. 

The previous world record was 46.80 set by Pan in February.

Americans Jack Alexy and Chris Guiliano, both 21-year-old first-time Olympians, finished seventh and eighth respectively.

Alexy qualified sixth and Guiliano seventh in Tuesday’s semifinals, and both were about half a second behind Pan, who qualified first.

Through the first half of swimming at the Paris Games, Guiliano and Alexy already have some Olympic hardware. Both were part of the gold medal-winning men’s 4x100-meter freestyle relay Saturday, and Guiliano added a silver medal to his stash in Tuesday’s men’s 4x200-meter freestyle relay behind Great Britain’s gold.
