DOHA, Qatar (CMC):Jamaica's Olympic double medallist Kerron Stewart logged another impressive sub-11 clocking and creamed the 100-metre field at the Qatar Athletic Super Grand Prix yesterday.

On an evening of high quality performances at the Doha meeting, world-leader Stewart, who won 100-metre silver and 200-metre bronze at the Beijing Olympics last year, clocked a fast 10.93 seconds to win with authority ahead of American Stephanie Durst and Jamaican Sheri-Ann Brooks.

That result served up the only Caribbean win on the programme as Jamaicans Michael Frater and Shericka Williams and the Bahamian Leevan Sands all secured podium finishes without winning.

Coming off last weekend's 2009 world best 10.92 victory at the Jamaica International meet in Kingston, the in-form Stewart outclassed her rivals in registering a clear win over Durst (11.15). Brooks, the reigning Commonwealth Games champion, was third in 11.20 seconds.

world-leading time

Frater clocked 10.15 seconds for second spot in the men's 100 metres behind American Travis Padgett, who won in 10.00 seconds and equalled Walter Dix's world-leading time.

After winning his heat (one) in 10.14 seconds, Frater tussled with heat two winner Padgett in the final and lost out to the American. Britain's Marlon Devonish was third in 10.19 seconds and Jamaican Nesta Carter finished a disappointing seventh in 10.34 seconds.

Carter had placed second behind Padgett in heat two in 10.15 seconds.

Williams, who picked up 400-metre silver in Beijing, was outgunned by Allyson Felix in the women's one-lap event.

The American toppled Jamaican Novlene Williams-Mills as world leader by winning in 50.75 to defeat Botswana's Amantle Montsho, who clocked the same time (51.08) as Williams in third position.

Felix's time eclipsed the 50.99 Williams-Mills posted in Kingston last weekend.

commanding win

Sands, a bronze medallist at the Beijing Olympics last year, had his best effort in the triple jump measured at 16.59 metres, giving him second spot behind the Frenchman Julien Kapek (16.64m). Grenada's Randy Lewis finished sixth at 16.25 metres.

In the women's 100-metre hurdles, Canada's Priscilla Lopes-Schliep posted a commanding win in a 2009 world best 12.52 seconds over Americans Damu Cherry (12.72) and Danielle Carruthers (12.73).

Jamaica's Lacena Golding-Clarke finished fourth in 12.78, her quickest time in four years.

World-leading David Oliver lowered his own best time this year with a fine win in 13.09 seconds in the 110-metre hurdles, dismissing fellow American Antwon Hicks (13.24) and Britain's Andrew Turner (13.31).

Jamaica's Maurice Wignall was sixth in 13.53.

Jamaican distance runner Mardrea Hyman also appeared at the meet and placed 10th in the women's 3,000 steeplechase in 10 minutes 08.05 seconds.
