Sprinter Justin Gatlin showed his dominance of the 2014 season as he won the 100 metres and the 200m in the final Diamond League event of the season in Brussels.
Gatlin, 32, produced a stunning performance over the shorter distance, storming away from a high-class field to win in a world-leading time of 9.77 seconds.
The victory saw him leapfrog fellow American Michael Rodgers, who finished second in 9.93s, in the overall standings and means Gatlin takes the Diamond League title of the second season running.
Then, just over an hour later, Gatlin produced an equally impressive display as he outclassed the rest of the field in the 200m to win in a time of 19.71s.
In the women's event, the 200m Diamond Race had also gone down to the final event, with USA's Allyson Felix, Commonwealth champion Blessing Okagbare and European gold medallist Dafne Schippers all in with a chance of taking the title.
It needed a world's best time this year to win it, Felix powering away from the field to take the victory, and her second 200m title, in a time of 22.02s. Okagbare finished a disappointing sixth but still took second overall, with Schippers in third.
The stand-out field event of the night, and perhaps the season, was the men's high jump.
Never before in one year had so many men cleared 2.40m, and heading into the final meet of the year in Belgium, both Bohdan Bondarenko of Ukraine and Qatar's Mutaz Essa Barshim had a chance of taking the title home.
As has happened on numerous occasions this year, the last jump of the night was a world record attempt, this time both the athletes attempting the 2.46m height. None could clear it, though, allowing Barshim to win the title with his 2.43m clearance - the second highest of all time.
Men's pole vaulter Renaud Lavillanie and women's shot putter Valerie Adams both also made history on the night.
Lavillanie's title in the event was his fifth in a row, the only athlete to win every year since the Diamond League was formed in 2010, while Adams, the Olympic champion from London 2012, won her event, and every one this season - the only person to have ever won all seven fixtures in any discipline.
There was also a special run in the men's steeplechase, with Jairus Birech of Kenya becoming only the 11th man ever to run under eight minutes when he clocked 7:58.41 to take the win.
