World champions Noah Lyles and Grant Holloway safely proceeded to their respective 200 metres and 110m hurdles finals at the US Olympic Team Trials in Eugene, Oregon, as did multiple former world champion Allyson Felix in the 200m.

In the absence of the Rio 2016 silver medallist Evan Jager through injury, the men’s 3,000m steeplechase title went to Hillary Bor in 8min 21.81sec, with the other two places being claimed by Benard Keter, who clocked 8:21.81, and Mason Ferlic, who recorded 8:22.05.

In the other final at the rebuilt Hayward Field today, the men’s discus, Mason Finley booked his Tokyo 2020 place with a winning effort of 63.07m and will be accompanied by Reggie Jagers, who threw 62.51m, and Sam Mattis, who reached 62.51m.

Lyles, whose hopes of attempting a sprint double in Tokyo were dashed he finished seventh in last Sunday’s 100m final, moved smoothly into tomorrow’s semi-finals in 20.19sec, following home 17-year-old prodigy Erriyon Knighton, who clocked 20.04.

Knighton's winning time broke Lyles' US high school record of 20.09, set at the US Olympic trials in Eugene five years ago.

Lyles said he had set out to qualify with a minimum of effort after exerting himself in the 100m earlier in the trials.

"Top two - there's no reason for me to gas out," said Lyles.

"It always feels natural when I come back to it."

The men's 200m final will bring the trials to a close on Sunday (June 27) evening.

Holloway qualified comfortably in 13.11 on a day when the final heat of the 110m hurdles only got away after four false starts, rousing the sparse spectator presence.

The first round of the women's 400m hurdles saw three false starts, and world silver medallist Sydney McLaughlin said her knees had started bleeding on the sun-baked track after being forced back to the blocks so many times.

McLaughlin won her heat impressively in 54.07, while the Olympic and world champion Dalilah Muhammad, whose early season was disrupted by having COVID-19, reached tomorrow’s semi-finals in 55.51.

Felix, 35, who has already earned a sixth Olympic appearance in the 400m, was third fastest into tomorrow’s 200m final in 22.20.

Harvard graduate Gabby Thomas, who had moved joint top in this year’s world lists with Olympic 400m champion Shaunae Miller-Uibo in recording 21.98 in the heats, moved clear at the top by running 21.94 in the semi-finals.

In the men's 400m hurdles world silver medallist Rai Benjamin looked in ominous form as he won his opening heat in 48.61, slowing over the final 50 metres.
