Gold for Bolt in 4th best 200 in history

Six days and a slow start later, Usain Bolt finally won gold at the world championships, running the fourth-fastest 200 metres in history to back up his showmanship with a stunning performance.After he was disqualified for a false start the 100 final last Sunday, Bolt was slowest out of the blocks before driving through the bend and powering to the line in 19.40 seconds, just .21 seconds of the world record he set to win his first world title two years ago.Knowing he had something to prove, there was no braggadocio during the race. Instead, he gritted his teeth in utter effort over the last 20 metres before dipping across the line for the fastest time in two years.Walter Dix of the United States won his second sprint silver in 19.70 and Christophe Lemaitre earned bronze with a French record of 19.80.In the high jump, Anna Chicherova of Russia beat two-time defending champion Blanka Vlasic of Croatia, and Matthias De Zordo of Germany overcame favourite Andreas Thorkildsen of Norway to win the mens javelin.Before Bolt took to the track, Sally Pearson ran the fastest 100 hurdles race in almost two decades to win gold. Pearsons time of 12.28 seconds was the fastest since 1992 and moved her up to fourth in the all-time list of performers.It was Bolts fourth gold over two world championships and he is expected to anchor his countrys 4x100 relay team on Sunday in another Jamaica vs. United States sprint duel.Allyson Felix now has done three better. The American ran the second leg on the winning 4x400 relay team to claim her seventh gold over four world championships.Felix and Sanya Richards-Ross failed to get gold in the individual 400 but running the first two legs of the relay, they built such a lead that the outcome was inevitable. They won in 3:18.09.Behind the Americans, Jamaica took silver in 3:18.71 and Russia earned bronze in 3:19.36.It was the third straight victory in the event for the United States, while Jamaica has now taken silver at the last four world championships.The Kenyans flaunted their confidence again on Saturday, extending their dominance of the middle and long-distance events with Olympic champion Asbel Kiprop leading Silas Kiplagat in the 1,500 for yet another Kenyan 1-2 finish.Earlier, Russia completed a sweep of the walking events, with Sergey Bakulin winning the 50-kilometer race ahead of teammate Denis Nizhegorodov. After Valeriy Borchin and Olga Kaniskina won the 20-kilometre events earlier in the week, Bakulin made sure of a second straight Russian walking sweep at the world championships.The walks and Chicherovas victory left Russia in second place in the medal standings with seven gold and 17 medals overall, behind the United States, which has 10 gold and 21 medals overall. Kenya is third with six gold and 14 medals overall.
