(AFP) Ashton Eaton cruised to his third consecutive heptathlon crown to complete a unique husband-and-wife double as American athletes dominated at the World Indoor Athletics Championships on Saturday.
Olympic and world decathlon champion Eaton wrapped up a comfortable victory in the multi-discipline event by cruising home in third place in the 1,000m to roars from his hometown crowd.
Eaton's win came just 24 hours after his wife -- Canada's Brianne Theisen-Eaton -- had snatched a dramatic last-gasp win in the women's pentathlon on Friday to claim her first world crown.
Pierre sinks Schippers
Barbara Pierre rounded out the host nation's gold haul in the final track event with victory in the women's 60m final.
Pierre took the tape with a time of 7.02sec, just holding off a surge from world 200m champion Dafne Schippers of the Netherlands, who finished with silver.
An unexpected American victory came in the men's 800m, where Boris Berian completed an extraordinary personal journey to take gold.
The 23-year-old was working in a McDonald's in 2014 but resurrected his career last season.
Elsewhere, the Czech Republic's Pavel Maslak became the first reigning 400m champion since Alleyne Francique in 2006 to successfully defend the title.
The talented 25-year-old surged past Bralon Taplin of Grenada in the home straight to win in 45.44sec, with Abdalelah Haroun of Qatar taking silver and Deon Lendore of Trinidad and Tobago the bronze.
Bahrain's Nigerian-born star Oluwakemi Adekokya won the women's 400m, withstanding a fierce late challenge from American duo Ashley Spencer and Quanera Hayes to come home in 51.45sec.
Adekokya, 23, controversially switched allegiances to Bahrain in 2014 despite complaints from athletics authorities in her native Nigeria.
Saturday also saw Dong Bin become only the third athlete from China to win a World Indoor Athletics Championships gold with victory in the triple jump. The 27-year-old from Changsha led the competition from start to finish, winning with a best leap of 17.33m.
