When Usain Bolt means business, he is still all alone out there.

Bolt coasted to his third straight 200-meter world title on Saturday with the race basically wrapped as soon as he entered the finishing straight.

Jamaican teammate Warren Weir never got close to Bolt's world leading time of 19.66 seconds, but crossing .13 seconds later for silver still left him enough time to join Bolt in a reggae dance to Bob Marley's "Three Little Birds."

"The energy was great tonight," Bolt said. "The crowd was in to it."

Curtis Mitchell of the United States took bronze in 20.24 seconds, but was never in the hunt for gold.

Now Bolt will go for his fourth triple gold at a major championship when he joins the Jamaican team for the 4x100 relay on Sunday.

His seventh world title leaves him one shy of American greats Carl Lewis and Michael Johnson, who lead the overall gold medal standings in the 30-year history of the event. On Sunday, Bolt can pull alongside them.

And with 10 medals overall, Bolt can overtake Lewis at the top with two silvers compared to a silver and bronze for the American sprinter-long jumper.

Even though he is only 26, Bolt's maturity showed Saturday as the wild hot-dogging of the Beijing Games gave way to a sense of near-seriousness.

His Lightning Bolt stance came late and besides the dance steps, everything was contained.

"I got to face the fact that I am getting older so I have to try not getting injured during the season," Bolt said.

The only thing that never changes is the gold.

The wealth of Jamaican sprinting is such that they might well sweep their American rivals in unprecedented fashion, after Shelly-Ann Fraser-Pryce clinched a similar 100-200 double and has her final relay also late on the closing day of the championships.

Opposition could hardly touch Bolt on Saturday, and once it was clear his right foot was OK after he dropped a starting block on it early in the week, everything was as good as gold.

Even his start was strong as he quickly gained a decisive edge.

In the finishing straight, Bolt fully let loose his giant stride, the one that has dumbfounded rivals since he won three gold medals at the 2008 Beijing Olympics.

Stephen Kiprotich secures men's marathon gold

A few zigzag moves near the end secured the men's marathon gold medal for Stephen Kiprotich.

The Olympic champion from Uganda used the moves to break free of Lelisa Desisa of Ethiopia shortly before entering Luzhniki Stadium on Saturday at the world championships. He then cruised home, waving to the fans and slapping the palms of others as he went by.

Kiprotich won in two hours nine minutes 51 seconds — 21 seconds ahead of Desisa, the winner of the Boston and Dubai marathons. Another Ethiopian, Tadese Tola, took the bronze, 32 seconds behind.

Rob Watson of Vancouver was 20th.

"I am super pumped about placing 20th, my ultimate goal coming in was a top 20 performance," he said. "When you're hurting and suffering but passing people it makes it that much easier, you're suffering for a cause, not just hanging on for dear life.

"I was ranked 48th coming in, I just wanted to beat people in a race."

No Kenyans were in the top three for the first time at a world championship since 2005. Kenyans had won the last three world titles.

The best Kenyan on a sunny and warm afternoon in Moscow was Peter Some in ninth place.

Ethiopians had four runners in the top eight, but failed to grab the coveted gold medal they've missed out on since 2001.

The three medallists were among six runners who pulled away from the pack after 35 kilometres. Some, including Tsegay Kabede of Ethiopia and Kentaro Nakamoto of Japan, were eventually dropped and the lead pack was left to decide the race alone.

Kiprotich then stepped up the pace at the 40th kilometre. Desisa followed but Tola dropped back.

Approaching the stadium, Kiprotich executed his zigzag moves, throwing Desisa off his rhythm and leaving him behind.

American Rollins wins women's 100-metre hurdles

Brianna Rollins of the United States won the women's 100-meter hurdles Saturday at the world championships with a late surge to the finish.

Rollins won in 12.44 seconds, just ahead of Olympic champion Sally Pearson of Australia. Pearson, who was also the defending champion, took silver in 12.50, while Tiffany Porter of Britain earned bronze in 12.55.

Edmonton's Angela Whyte highlighted Canada's performance finishing 6th in 12.78 seconds.

"I'm so happy I made the final, but now we re-evaluate and see what I need to do to really be in the medal mix," Whyte said. "I'm just happy to be back at a world class level after knee surgery in 2008."

"I got out relatively well, came off hurdle one and collapsed quite a bit," she said. "It wasn't the time I was looking for, I didn't execute as cleanly as I wanted to, but I responded well and battled back."

Jessica Zelinka of London, Ont., was eliminated in the semifinal earlier Saturday with a time of 13.12 seconds.

Dawn Harper, the 2008 Olympic champion from the United States who won bronze at the worlds two years ago, was fourth.

Meseret Defar wins women's 5,000 metres

Meseret Defar regained the women's 5,000-metre title at the world championships on Saturday, coming out of the slipstream of Ethiopian teammate Almaz Ayana to win gold with a strong finish.

Defar, the 2007 world champion, finished in 14 minutes, 50.19 seconds, beating silver medallist Mercy Cherono of Kenya by 1.03 seconds.

Ayana did most of the heavy work for Defar but weakened near the end. She still won her first major championship medal with a time of 14:51.33.

Ethiopia also won the 10,000 in Moscow with Tirunesh Dibaba taking gold during the opening weekend.

Two-time defending 5,000 champion Vivian Cheruiyot of Kenya missed the worlds this year because she is having a baby.

Russia wins 4x400 relay

Russia won the women's 4x400-meter relay at the world championships, holding off the United States at the end.

The Russian team of Yulia Gushchina, Tatyana Firova, Kseniya Ryzhova and Antonina Krivoshapka won the race in 3 minutes, 20.19 seconds.

The defending champion American team, with Jessica Beard, Natasha Hastings, Ashley Spencer and Francena McCorory running, finished second in 3:20.41.

The Americans ran without Allyson Felix, who tore her right hamstring in the 200 final on Friday.

Britain earned bronze in 3:22.61.

 Russia's Shkolina takes women's high jump

Svetlana Shkolina of Russia won the women's high jump at the world championships on Saturday with a leap of 2.03 metres, beating Brigetta Barrett of the United States by three centimetres.

Olympic champion Anna Chicherova of Russia, who is also the defending world champion, shared bronze with Ruth Beitia of Spain. Both cleared 1.97.

Emma Green Tregaro of Sweden, who wore rainbow-colored fingernails during qualifying to show support for Russian gays and lesbians in the face of an anti-gay law, finished fifth in the final, with red nails.

With one attempt to go for 2.03, Barrett mistimed her steps on her run-up and didn't even jump before slumping against the mat.

Vesely of Czech Republic wins men's javelin

Vitezslav Vesely of the Czech Republic won the men's javelin at the world championships on Saturday with a throw 87.17 metres, edging 2007 champion Tero Pitkamaki of Finland by 10 centimetres.

Dmitri Tarabin of Russia took bronze on his last throw with a mark of 86.23. He pushed Julius Yego out of medal contention, leaving the Kenyan to settle for a national record of 85.40 in fourth.

Vesely set the top mark on his first throw and only Pitkamaki got close on his third attempt.

Two-time Olympic champion Andreas Thorkildsen of Norway, who was also the 2009 world champion, finished seventh.
