Shelly-Ann Fraser-Pryce kept the 60 metre world indoor title in Jamaica on Sunday in Sopot, Poland, beating Murielle Ahoure of Ivory Coast and Tianna Bartoletta of the United States.
With the fastest run by anyone in four years, Fraser-Pryce led from the start to finish in 6.98 seconds, adding a first indoor gold to two Olympic sprint and five world outdoor titles. Ahoure was .03 seconds back and Bartoletta timed 7.06.
Veronica Campbell-Brown was the double defending champion but still too rusty to be at her best as she was only cleared at the last moment to compete at the championships after a doping scandal had sidelined her since last summer.
The result proved Jamaica's sprint credentials again, but overall the day and the championships again belonged to the United States. Going into the final events Sunday, the U.S. team had seven gold and 11 overall, more than double the total of runner-up Russia, which had three gold and five overall.
The first U.S. gold Sunday came in the women's 800, where Chanelle Price did all the frontrunning and refused to fade over the final two laps, as she disregarded the massive cheers of the home crowd that was pushing for Angelika Cichocka. Price finished in a world-leading 2:00.09, and held a .39 gap over Cichocka.
Then, the 4x400 team led from start to finish to easily win the relay ahead of Jamaica and Britain.
And in the wide-open 60 hurdles, Omo Osaghae dipped at the line to beat two Frenchmen in a world leading 7.45. Pascal Martinot-Lagarde was .01 back and Garfield Darien a further .01 second in a tight finish.
In individual races, no one was as overwhelming as Genzebe Dibaba. She breezed to a gold medal in the 3,000 metres, failing to add a third world record in a season but clinching a long-distance title after the 1,500 two years ago.
Dibaba knew from the start she was in a league all her own, and when she took charge at the halfway point only a few could match her pace. With a kick for home with two laps to go, the Ethiopian immediately created a yawning gap, leaving silver to defending champion Hellen Obiri of Kenya and bronze to Maryam Yusuf Jamal of Bahrain.
Dibaba had already set world records in the 1,500 and 3,000 and a world best over 2 miles this winter but decided against a double in Sopot because it would be too draining.
"It's been a great year for me," said the younger sister of Tirunesh Dibaba, the triple Olympic and five-time world long-distance champion.
"Tirunesh also wanted me to focus on the gold and not the time," she said. "I have done what they hoped and expected."
Mohammed Aman added to a good day for Ethiopia when the 800 defending champion swept past two Polish runners to take another gold. Adam Kszczot got silver. Teammate Marcin Lewandowski crossed in third place but was later disqualified.
Kszczot' silver delighted the home crowd at the Ergo Arena after Anna Rogowska had failed to live up to expectations in the pole vault, finishing fifth behind gold medallist Yarisley Silva of Cuba, who scaled 4.70 metres. Two silver medallists Anzhelika Sidorova of Russia and Jirina Svobodova of the Czech Republic scaled the same height but missed out on the title on a countback.
Olympic champion Jenny Suhr only cleared 4.65 before she skipped the next height and failed three times at 4.75.
In Canadian results, Cameron Levins of Black Creek, B.C., finished eighth in the men's 3,000-metre final in a time of 7:57.37. Shortly after in the high jump final Michael Mason of Nanoose Bay, B.C., cleared 2.25 metres landing him in eighth place as well.
Canada finished the meet with two medals. Brianne Theisen-Eaton of Humboldt, Sask., won silver in the pentathlon on Friday with a Canadian indoor record of 4768 points. Nicole Sifuentes of Winnipeg captured the bronze medal in the women's 1500-metres on Saturday, also in a Canadian indoor record of 4:07.61.
"This was a great performance for our team at a very high level indoor World Championships," Athletics Canada head coach Peter Eriksson said. "With 60 per cent of the team making finals, and winning two medals, I will definitely grade that as passing the mark."
In other Canadian results, Damian Warner of London, Ont., was seventh in the heptathlon, Toronto's Gavin Smellie was eighth in the men's 60-metre semifinal, Nathan Brannen of Cambridge, Ont., finished sixth in the men's 1,500 metres and Calgary's Jenna Westaway placed fifth in her opening heat of the women's 800 metres.
