Bleasdale wins with season's best
Britain's Holly Bleasdale set a season's best of 4.75 metres to win the pole vault at the Russian Winter meeting in Moscow.
Bleasdale, who finished sixth in the London Olympics last year, needed three attempts to clear 4.65m, but then cleared 4.70m with her second attempt and 4.75m at the first time of asking.
Three failures followed at 4.80m, but the 21-year-old had already done enough to win the competition ahead of 2011 world champion Fabiana Murer of Brazil (4.65m).
That was the only British victory of the day, with Dwain Chambers having to settle for second in the 60m behind fellow veteran Kim Collins.
Chambers, 34, won his heat in 6.65 seconds and although he went quicker in the final (6.63secs), the 36-year-old Collins clocked a superb 6.57s to claim victory.
Mark Lewis-Francis could only finish fourth in his heat in 6.78s to miss out on the final, while Anyika Onuora also failed to reach the women's final after finishing third in her heat in 7.43s.
Chris Tomlinson was second in the long jump with a best of 7.83m, with Shara Proctor (6.44m) fourth in the women's event.
