CANBERRA sprinter Melissa Breen set a world championship A qualifying standard at the Sydney Track Classic on Saturday night, clipping two-hundredths of a second off her personal best time in winning the women's 100 metres in 11.25 seconds.
After recording 17 B-Qualifying times for last year's Olympics before being granted a discretionary selection to London by Athletics Australia, Breen was delighted to get an A standard so early in the season.
The PB was even sweeter for Breen, as she did not have injured Olympic 100 metres hurdles champion Sally Pearson to push her.
''To see that time, it's just incredible,'' said Breen.
''Obviously not to go through what I did last year was the plan. Training has been unreal since the Olympics. I haven't missed a session in seven months.
''I honestly couldn't ask for a better prep and without Sally I had an expectation that I should be running quick.''
Meanwhile, former world discus champion Dani Samuels produced her best series of throws since 2010 as she registered five world championship A qualifying standards.
Samuels, the 2009 world champion, who finished 12th at the London Olympics, threw 62.19 metres, 64.06, 64.46, 63.65, 60.74 and 63.50 and was thrilled by the implications for her 2013 season.
''2011 wasn't very good, I came away with an OK season's best in 2012 - 63.97,'' Samuels said. ''But to have a series like that and go over 64, it hasn't been since 2010.
''I really enjoyed it tonight, it was great conditions, the wind was favourable.
''I want to win a medal at the world championships, that's always a goal, and it gives me great confidence leading into Europe.''
Sydney's Tim Leathart (10.24 seconds) produced the first upset of the night, shading dual Olympian Josh Ross (10.25) and American Calesio Newman (10.29) in the men's 100 metres.
Overseas winners included the Netherlands' Susan Kuijken (women's 5000m, 15:43.20), New Zealander Elizabeth Lamb in the women's high jump (1.84m) and fellow Kiwi Michael Cochrane (men's 400m hurdles, 50.07).
The IAAF World Athletic Championships will be held in Moscow from August 10-18.
