Here's the must-see action on the second day of the 2016 Summer Olympics in Rio.
Sunday, August 7 (all times Eastern)
9:45 am. — Tennis: First Round
After winning the French Open in June, Novak Djokovic completed the career Grand Slam and became the reigning champion of all four major tournaments. Next up: winning Olympic gold, which would solidify his spot atop the tennis world.
2:00 p.m. — Synchronized Diving: Women’s Three-Meter Springboard
Canada's Jennifer Abel and Pamela Ware team up with the 10-meter duo of Roseline Filion and Meaghan Benfeito to form the Fab IV. Abel (below) and Ware are the favorite here. They might try dive 5154B, which sounds like a Star Wars character but is actually two-and-a-half somersaults and two twists.
9:00 p.m. — Swimming
At 19, Katie Ledecky already has the Ledecky Slam named after her. It entails winning a gold medal in every freestyle event, which Ledecky did at the 2015 world championships. Her quest to pull off an Olympic version begins with the finals of the 400-meter free, an event she won in the 2012 Games as a 15-year-old.
