KINGSTON, Jamaica (CMC)

Jamaica's Olympic silver medallist Kerron Stewart won the women's 100 metres in a world-leading 10.92 seconds at the Jamaica International Invitational meeting on Saturday night.

Stewart won ahead of American Marshavet Hooker (11.14) with Jamaica's reigning Olympic champion Shelly-Ann Fraser third in 11.15 seconds.

In two other world-leading performances at the National Stadium, Puerto Rico's Javier Culson landed the men's 400-metre hurdles in 48.42 seconds and Jamaica's Novlene Williams-Mills took the women's 400 in 50.99.

won with authority

Stewart, who shared silver with her teammate Sherone Simpson, in the 100-metre final in Beijing, won with authority as she eclipsed American Carmelita Jeter's previous 2009 world best 10.96 seconds.

"It's a good time. It's better than what I ran last year, so I think I am right where I need to be," Stewart told reporters after the race.

Fraser edged Jamaican Aleen Bailey (11.15) for third while two other Caribbean runners, Trinidad and Tobago's Kelly-Ann Baptiste (11.17) and the British Virgin Islands' Tahesia Harrigan (11.47) placed fifth and eighth, respectively.

Bailey won the 200 metres in 22.96 ahead of America's Bianca Knight (23.15).

Williams-Mills, a bronze medallist at the 2007 World Championship, bettered American Monica Har-grove's 51.00 as the quickest this year as she toppled top American Sanya Richards (51.12) with local runner Rosemarie Whyte third in 51.85.

surprise winner

Culson ran a strong race to be the surprise winner of the men's 400 hurdles, defeating Jamaican Isa Phillips (48.79) and American Michael Tinsley (48.81).

In a fiercely contested men's 100 metres, American Darvis Patton edged Antiguan Daniel Bailey for a victory in 10.02 seconds, both clocking the same time and were only 0.02 off Walter Dix's world-leading time.

Jamaican Yohan Blake (10.07) was third, a shade ahead of T&T's Olympic silver medallist Richard Thompson, who also came in at 10.07.

In other men's events, T&T's Renny Quow won the 400 metres in 45.41 seconds over Jamaica's former Commonwealth Games champion Michael Blackwood (45.54) and American world leader and Olympic silver medallist Christian Cantwell won the shot at 21.16 metres.

Jamaica's women picked up two other wins when Olympic finalist Kenia Sinclair narrowly took the 800 metres in two minutes 01.02 seconds ahead of Cuban Culia Torres (2:01.19) and Nickeisha Wilson (55.20) captured the 400 hurdles.
