Athletics: Bernard Lagat became the first American man to win a global 1,500 metres title for 99 years when he swept to victory down the home straight at the world championships in Osaka, Japan.
The Kenyan-born 32-year-old only qualified to run for his adopted country last year but his time of three minutes 34.77 seconds was enough to a break an American drought stretching back to the 1908 Olympics.
A 1,500m silver medallist for Kenya at the 2001 world championships and 2004 Olympics, Lagat was thrilled to win his first major title for the United States.
"I have never been happier than this," he said. "I've been wearing the flag since I crossed the line and it feels fantastic.
"It was a dream come true. I am a champion. I've never felt like this."
Defending champion Rashid Ramzi of Bahrain followed Lagat through the line to claim silver in 3.35.00 ahead of Kenyan Shadrack Korir, who took bronze in 3.35.04.
"Peerless" Mel Sheppard was the last American man to win a global 1,500 metres title when he did the middle distance double at the London Olympics of 1908.
"I said, 'I think I'm going to win it' and I kept on going," Lagat said. "I got it but I didn't know how to celebrate because I'd never been number one before."
Britain's Christine Ohuruogu produced a fantastic late fightback to win an emotional gold medal in the women's 400 metres.
Ohuruogu caught Jamaican Novlene Williams in the last few metres in a pulsating final to win in 49.61 seconds with fellow Briton Nicola Sanders taking silver in 49.65.
Williams, who had looked to be home and dry coming off the final bend, had to settle for the bronze in 49.66.
Ohuruogu's victory completed a remarkable comeback for the Commonwealth Games champion, who has just returned from a year's suspension for missing three out-of-competition doping tests.
"This time last year I was in complete turmoil," she said. "I didn't know what I was doing. It hasn't quite sunk in yet. I'm just very happy I worked hard and everything came together at the right time.
"On the finish line I said 'was it me?'... it's unbelievable," she said. "I had butterflies I can tell you. Never in my wildest dreams could I have thought of coming back after my ban as world champion," she added, her voice breaking with emotion.
Tyson Gay stayed on course for a world championship sprint double by qualifying fastest for tomorrow's 200 metres final.
The American, who won gold in the 100m, coasted home in 20.00 seconds in the second semi-final with Jamaica's Usain Bolt winning the first in 20.03.
Gay, inspired by Sunday's victory over 100m world record holder Asafa Powell, cruised home despite feeling a twinge in his left hamstring coming out of the blocks.
"I had a little (hamstring) trouble at the start and in the curve," he said. "Whatever I've got left in the tank is for the final. I'm going to give it all I've got."
