In Olympic rematch, 800m champion Wanyonyi pulls away from Canada's Arop at Lausanne event

Fresh off his silver medal at the Paris Olympics, Canada's Marco Arop returned to the track and finished second in the men's 800-metre event on Thursday in Lausanne, Switzerland.

In a rematch of Paris, Olympic champion Kenya's Emmanuel Wanyonyi was able to hold off Arop down the stretch, this time with a more sizeable margin.

Wanyonyi finished in a world-leading, and personal-best time of one minute 41.11 seconds in the non-official Diamond League event. It was also the fourth-fastest 800m time in history.

Arop, 25, ended his race in 1:41.72, and France's Gabriel Tual placed third in 1:42.30.

At the Paris Olympics, Edmonton's Arop stopped the clock in a Canadian-record time of 1:41.20. Wanyonyi held on for gold, beating Arop by one-hundredth of a second in 1:41.19.

Arop's Olympic medal was Canada's first in the event since Bill Crothers earned silver at the 1964 Tokyo Games, and fifth ever.

Arop entered the Olympics as the reigning world champion in the event and also claimed bronze at the 2022 world championships. He is also the second Canadian to medal in the men's 800 at a world championship alongside Gary Reed's silver in 2007.

Sarah Mitton, of Brooklyn, N.S., finished third in the shot put event with a throw of 19.52 metres.

American Chase Jackson won the event with a season-best toss of 20.64. Yemisi Ogunleye placed second at 19.55.
