Caeleb Dressel leads U.S. to gold in men's 4x100-meter freestyle relay

Tokyo — Caeleb Dressel got started on his quest for six gold medals in swimming, while Katie Ledecky found herself in a very unusual position: second place.

Dressel led off a U.S. victory in the men's 4x100-meter freestyle relay Monday at the Tokyo Olympics, easing a bit of America's sting from Ledecky's first Olympic loss. Australian Ariarne Titmus - nicknamed the "Terminator" - lived up to her billing when she chased down Ledecky in the 400 freestyle to win one of the most anticipated races of the Summer Games.
