In the marquee event of Day 3 of the World Athletics Championships in Budapest, American Sha'Carri Richardson stormed back to defeat rivals Shericka Jackson and Shelly-Ann Fraser-Pryce of Jamaica to win gold in the women's 100 metres.

Richardson barely qualified for the final after placing third in her semifinal heat earlier in the day. Running in the outside Lane 9, she used a late surge to clock a world-championship record 10.65 seconds and shock Jackson (10.72) and Fraser-Pryce (10.77), the 36-year-old icon who was gunning for her third consecutive 100m world title and sixth of her career.

This is the 23-year-old Richardson's first appearance in a major global championship. She was suspended for the Tokyo Olympics for testing positive for cannabis and then failed to qualify for last year's worlds.

Also today, American Grant Holloway won his third consecutive world title in the men's 110m hurdles. Read more about the top results from Day 3 and watch highlights here.

The Canadian highlight of opening weekend was Ethan Katzberg's surprising gold medal in the men's hammer throw. Making his world-championships debut, the hirsute 21-year-old from Nanaimo, B.C., lengthened his own Canadian record to 81.25 metres to defeat reigning Olympic champion Wojciech Nowicki of Poland, who got the silver with a toss of 81.02m. Defending world champ Pawel Fajdek of Poland finished fourth.
