Watch Live (5 p.m. PT, Monday): Track and Field

USC’s Rai Benjamin has a shot at a medal when he competes in the final of the men’s 400m hurdles at the Tokyo Olympics.

Benjamin, the world’s No. 2 in the event, faces a tough field that includes the reigning world champ, Norway’s Karsten Warholm. The 400m hurdles final is scheduled to begin at 8:20 p.m. PT.

Only four men have ever cracked 47 seconds in the event. On July 1, Warholm broke a 29-year-old record held by Kevin Young when he finished in 46.70 in his first race of the season, in Oslo.

The others to crack 47 are Samba Abderrahman, the Qatari who is also in Tuesday’s final and Benjamin, the American who ran 46.83 at Olympic trials in June.

Benjamin is a junior at USC. He transferred from rival UCLA with two seasons of eligibility remaining.

Los Angeles’ Allyson Felix beings her quest for her 10th Olympic medal when she competes in the first round of the 400m dash. That heat is scheduled to begin at 6:01 p.m. PT

April Ross and Alix Klineman Face Germany in Beach Volleyball Quarterfinal

Watch Live (5 p.m. PT): USA v. Germany

April Ross and Alix Klineman are back on the beach for a quarterfinal matchup with Germany in Tokyo.

Ross, of Costa Mesa, and Klineman, of Manhattan Beach, held off Olympic newcomers Cuba in their first Round of 16 test after going 3-0 in pool play. Ross and Klineman stormed back after trailing early in the second set to earn a hard-fought 21-17, 21-15 win. 

Ross and Klineman play Germany’s Laura Ludwig and Margareta Kozuch at 5 p.m. PT Monday. You can stream the match here. Ludwig was on the German team that defeated Brazil to win the gold medal in Rio.

Ross is a three-time Olympian who has already won silver and bronze. She paired with first-timer Klineman after parting ways with beach volleyball icon Kerri Walsh Jennings after they won bronze in Rio. 

The two have been playing together for three years and won silver at the 2019 World Championships.

Despite withdrawing from almost all gymnastics events at the Tokyo Olympics, Simone Biles has had perhaps the most closely watched and discussed week of any Olympian this year. From being a gymnastics favorite to becoming a champion for mental health, here’s a timeline of Biles’ week at the 2020 Olympics.

Biles left the team final last week and has since withdrawn from finals in the individual all-around, vault and floor exercise. Team USA has stepped up without Biles — Lee won gold in the individual all-around, MyKayla Skinner earned a silver medal in vault and Jade Carey brought home another goal in the floor exercise.
