Isinbayeva rounds off a fine home performance in Moscow

The 23-year-old retained her pole vault title, but failed in an attempt to raise her world record by 2cm to 4.93m.

Ethiopian Meseret Defar defended her 3,000m title, with home favourite Lilya Shobukhova having to settle for silver.

Terrence Trammell won gold in the 60m hurdles in 7.43 seconds, the fastest time in the world this year.

The American, running his sixth race in two days after winning bronze in the 60m on Friday, beat Cuban Dayron Robles into second with compatriot Dominique Arnold third.

Shobukhova had won the host nation's first medal of the day in finishing behind Defar.

The world record would have been the icing on the cake but it's hard to break records Yelena Isinbayeva

Olympic 5,000m champion Defar, 22, finished strongly to win in a time of eight minutes, 38.80 seconds after Shobukhova fell away having led for much of the race.

But Tatyana Lebedeva ensured the crowd were on their feet shortly afterwards as she led a one-two in the women's triple jump, before Yaroslav Rybakov and Andrey Tereshin repeated the feat in the men's high jump.

Olympic champion Isinbayeva, arguably the biggest draw of the Games, kept the momentum going when she retained her pole vault crown, clearing 4.80 in the final event of the day.

Poland's Olympic bronze medallist Anna Rogowska claimed silver by clearing 4.75, with Russian former world champion and Olympic silver medallist Svetlana Feofanova third with a jump of 4.70.

But even Isinbayeva's failed attempt at 4.93m did not dampen her spirits as she said: "I was hungry to win and give the crowd something to cheer about.

O'Rouke celebrates a maiden win for Ireland at the Games

"The most important thing for me was to win. The world record would have been the icing on the cake but it's hard to break records."

While the Russians were adding to their medal tally, Derval O'Rourke became the first Irishwoman to win a title at the championships with victory in the 60m hurdles.

Saturday's other medals went to Ukraine's Ivan Heshko in the men's 1,500, and Ghanaian Ignisious Gaisah in the long jump.

Britain's Jimmy Watkins beat his personal best for the second time in 24 hours to reach Sunday's 800m final.

The 23-year-old, who was left out of Wales Commonwealth Games team, recorded a time of one minute 47.23 seconds to finish third in his semi-final.

"I hope the Welsh selectors are embarrassed," said Watkins.

Team-mates Jenny Meadows and Sarah Claxton both failed to progress to leave just three British medal hopes on Sunday.
