MOSCOW, Aug. 13 (Xinhua) -- Russia's "pole vault queen" Elena Isinbaeva ignited the Luzhniki stadium as she claimed her third world title on the fourth day of the 2013 World Championship here on Tuesday, which saw host Russia harvested two gold and one silver medals in seven finals.
The 31-year-old Russian leaped past 4.89m in the first attempt and saw off America's Olympic champion Jennifer Suhr and Cuba's world leading vaulter Yarisley Silva to secure the gold.
Isinbaeva, the 2005 and 2007 world titlist, then launched a challenge to her own world record, trying to clear 5.07, but failed in all the three attempts.
Suhr, who broke Isinbaeva's indoor world record in March, took the silver at 4.82m with a better countback while the bronze went to Silva, silver medalist at London Games.
"I am very happy for Yelena because she managed to please the home crowd. She really raised the standard of this event and I know it will be only her personal decision if she comes back to competing after a break," said Suhr.
"It is very hard to jump a World record at this kind of competition: there is too much emotions, adrenaline, tiredness. I am happy with the energy the crowd gave her, and I wish her the best."
Isinbaeva ignited the crowds at Luzhniki stadium in the evening session while Russia's London Olympic champion Elena Lashmanova led a one-two finish in women's 20-kilometer walk to jazz up the local spectators in the morning.
The 21-year-old Lashmanova, who set a world record when securing Olympic gold in London last summer, clocked one hour, 27 minutes and eight seconds to claim the title. Lashmanova has been enjoying a splendid 2013, as she clocked a season's best of 1:25: 49 to land the Russian title in Sochi and has secured IAAF Challenge victories in Rio Maior and Sesto San Giovanni.
Her countrywoman Anisya Kirdyapkina, gold medalist at the World University Games in Kazan last month, finished three seconds in arrears to take the silver.
The hosts could have enjoyed a podium sweep but Vera Sokolova, European Cup runner-up, received the third warning and was disqualified in the final kilometers when she was chasing the leading duo.
"I'm happy to win a gold medal in the capital of my home country. I am even happier that we've made it the Russian 1-2. It' s a pity that Sokolova was disqualified near the stadium in the end of the race. It could have been the three of us on the podium, " said Lashmanova.
"The judges did not really explain to us that should do one lap before the home straight and finish. That's why I stopped for a second at the stadium, but I quickly understood I should keep going," said Lashmanova, who believed she had crossed the "finish line" in a state of confusion when she still had another lap to cover.
Momentarily celebrating her success, she was then told to carry on a further lap of the Luzhniki Stadium but made the same mistake again on the top bend, allowing Kirdyapkina, bronze medalist in Daegu, to narrow the gap to only 3 seconds on the time sheets.
China's Liu Hong, the 2009 world bronze and 2011 world silver medallist, clocked 1:28:10 to take the bronze.
The American also enjoyed a one-two finish in the men's 400m race. Former Olympic and world champion LaShawn Merritt clocked a world leading time of 43.74 to win the gold while Tony Mcquay of finished second in a personal best of 44.40. Luguelin Santos of Dominican Republic took the bronze in 44.52.
"I've said it many times already, I was hungry. Probably the hungriest person in the field. No, I was starving. It's been a while since I was able to perform at my highest level. I was mentally and physically confident, I knew what I had to do, so I just had to produce it. As for the time, that race didn't feel that hard, so I think faster times will definitely come," said Merritt gold medalist in 2008 Olympics and 2009 worlds.
The women's steeplechase event also witnessed a world leading performance on Tuesday as Kenya's Milcah Chemos Cheywa clocked 9 minutes 11.65 seconds to grab the gold.
Cheywa's compatriot Lydia Chepkurui pocketed the silver in 9:12. 55 while Sofia Assefa of Ethiopia earned the bronze in 9:12.84.
The absence of Olympic champion Jessica Ennis-Hill left the women's heptathlon wild open with the top five finishers all achieving personal best in Moscow.
Ukraine's Ganna Melnichenko claimed the title in 6586 points while Canada's Brianne Theisen Eaton, wife of America's world record holder Ashton Eaton who won the men's decathlon world title on Sunday, finished second in 6530 points.
Dafne Schippers of the Netherlands set a new national record of 6477 to take the bronze.
Defending champion Robert Harting of Germany proved his high- level consistency as he claimed the third straight discus world title with the winning mark of 69.11 meters in the fourth round.
Poland's Piotr Malachowski, 30, took the silver with a fifth round effort of 68.36 while Gerd Kanter of Estonia, gold medalist at 2008 Beijing Olympics, notched the bronze at 65.19.
