Men's Hammer
Qualifying (8:00pET)
Poland's Pawel Fajdek is the four-time reigning world champion; however, he's yet to earn an Olympic medal — in Rio, he didn't make it out of the qualifying round.
His compatriot Wojciech Nowicki did make the Rio podium, finishing with bronze, a medal he also won at the last three world championships behind Fajdek from 2015-2019.
Rudy Winkler broke the American record at U.S. Olympic Trials with an 82.71m (271' 4") heave.
Women's 1500m
1st Round (8:35pET)
Sifan Hassan of the Netherlands continues her quest to triple with her second event's prelim following the 5K. She's the world record-holder at the one mile.
Defending Olympic champion Faith Kipyegon of Kenya, the 2017 world champion, was runner-up to Hassan at the most recent world championships in Doha.
The American contingent, missing its national record-holder Shelby Houlihan due to an anti-doping sanction, boasts U.S. indoor mile and two-mile record-holder Elle Purrier St. Pierre.
Heat 2: Hassan, USA's Purrier St. Pierre
Heat 3: Kipyegon
Men's Long Jump
Final (9:20pET)
Cuba's Juan Miguel Echevarria, bronze medalist at the 2019 World Championships, was the top qualifier to advance to the final, opening up with a season-best 8.50m.
World leader Miltiadis Tentoglou of Greece was the second-best overall qualifier with 8.22m. He was 10th in Doha.
Jamaica's Tajay Gayle initially appeared to have been injured, but came back for a final jump and qualified with 8.14m.
American JuVaughn Harrison, attempting the high-long jump double, jumped 8.10m to finish fifth overall in qualifying and advance.
Women's 200m
1st Round (9:30pET)
Defending Olympic 400m champion Shaunae Miller-Uibo of the Bahamas seeks gold in the 200m, an event in which she earned bronze at 2017 worlds. She petitioned for a change to the Tokyo schedule to better accommodate a 200-400 double attempt but was unsuccessful, so her focus turned to the shorter sprint.
American Gabby Thomas has the world-lead, set at June's U.S. Olympic Trials — the time, 21.61, catapulted her to No. 2 all-time behind world record-holder Florence Griffith-Joyner, the third-fastest 200m ever run.
Jamaica's Elaine Thompson-Herah, the defending Olympic champion and 2015 world silver medalist, and Shelly-Ann Fraser-Pryce, the 2012 Olympic silver medalist, attempt to add another medal from the Tokyo Games after winning gold and silver in the 100m.
Heat 1: Miller-Uibo
Heat 2: Fraser-Pryce
Heat 4: USA's Thomas
Heat 6: Thompson-Herah
Women's 100m Hurdles
1st Round (9:30pET)
World leader Jasmine Camacho-Quinn of Puerto Rico won her 100m hurdles semifinal in 12.26, taking down Australian Sally Pearson's 12.35 Olympic record from the 2012 London Games. That made her the joint-fourth fastest all-time in the event.
The woman atop that list, world record-holder Keni Harrison of the U.S., advanced to the final with a 12.51 second-place finish in section two.
Camacho-Quinn also had the top time of the first round, winning prelim five in 12.41. Harrison won the second heat in 12.74.
Harrison's all-time mark, set shortly after missing USA's Rio Olympic team in 2016, is 12.20.
