Team USA Trio Advances in Women's 100m on First Night of Track and Field

In the first session of track and field at the Tokyo Olympics, many Americans advanced to the next stage, including all three women in both the 100m and 800m, but Hillary Bor surprisingly failed to finish with a good enough time in the men’s 3000m steeplechase. Here’s how the first events went at Japan National Stadium:

Americans move forward in women's 100m

In a blistering set of heats in the women’s 100m, Marie Josee Ta Lou of the Ivory Coast had the fastest qualifying time at 10.78, followed by Jamaica’s Elaine Thompson-Herah at 10.82 and Olympic legend Shelly-Ann Fraser-Pryce at 10.84.

All three Americans -- Teahna Daniels, Javianne Oliver and Jenna Prandini, who replaced Sha’Carri Richardson in the event – also advanced to the semifinals on Saturday at 6:15 a.m. ET. The finals will follow at 8:50 a.m.

Bor fails to advance in steeplechase

In the first event of track and field at the Tokyo Olympics, Hillary Bor surprisingly did not advance to the final in the men’s 3000m steeplechase after having finished seventh overall at the 2016 Rio Games. He was in the third heat, where the runners ran at a much slower pace than their counterparts in the first two heats.

Among the other Americans, Benard Keter advanced after finishing in 8:17.31, good enough for sixth in the second heat, and Mason Ferlic finished eighth in the first heat.

American men advance in the 400m hurdles

All three Americans in the men’s 400m hurdles advanced to the semis after their performances in the heats. Rai Benjamin and Kenneth Selmon had the fourth (48.60 seconds) and fifth (48.61) fastest times overall. Dave Kendziera was toward the back of the pack with a time of 49.23.

Here's a clip of the race:

Mixed results in high jump and discus for American men

Two American men moved forward in the high jump. Juvaughn Harrison and Shelby McEwen each jumped 2.28m. Darryl Sullivan did not make it to the final on Sunday, Aug. 1 at 6:10 a.m.

Sam Mattis was the only American to advance in the discus throw, with his best throw at 63.74m, good enough for eighth out of the 12 athletes moving forward. The final will be Saturday at 7:15 a.m. ET.

Reggie Jagers and Mason Finley’s Olympics come to an early end.

Track and field action continues at 6 a.m. ET Friday with the first medal event, the men's 10,000m, as well as the Olympic debut of the mixed 4x400m relay.
