The men’s 4x100-meter freestyle relay brought home the first gold medal for Team USA, across all sports, at the Paris Olympic Games. The quartet of Jack Alexy, Chris Guiliano, Hunter Armstrong, and Caeleb Dressel clocked a 3:09.28, thanks largely in part to Armstrong’s 46.75 split on the third leg. The first-place finish marked the third-consecutive Olympic gold for the U.S. in the event. The relay also featured prelims swims from Ryan Held and Matt King.
