There was plenty of Olympics action on day three of the Tokyo Games Monday.
The big picture: Highlights for the U.S. included Caeleb Dressel leading Team USA to Olympic gold in the 4x100-meter freestyle relay and Regan Smith setting a new swimming record. Outside U.S. success, Japan's Momiji Nishiya, 13, won the inaugural Olympic women's skateboarding gold — one of the Games' youngest ever winners.
