Olympic silver medallist, Kerron Stewart, believes she is on target for this year's World Championships after toppling Olympic champion Shelly-Ann Fraser on the way to a world-leading 10.92-second victory in the women's 100 metres at the Jamaica International Invitational track and field athletics meet at the National Stadium on Saturday night.

Running in the middle of the track, the powerfully built Jamaican easily disposed of challenges from Fraser and American Marshevet Hooker to take the female glamour event. Hooker was second in 11.14, while Fraser placed third in 11.15, the same time as Aleen Bailey who placed fourth.

Good time for stewart

"It's a good time," said Stewart, who tied for second with Jamaican teammate Sherone Simpson in the 100m final in Beijing and claimed third in the 200m final.

She added: "It's better than what I ran last year, so I think I am right where I need to be."

The previous 2009 best was the 10.96 recorded by American Carmelita Jeter.

Bailey, the 2004 Olympic relay gold medallist, returned to take the women's 200m in 22.99, ahead of American Bianca Knight (23.15). Jamaica's Anastasia LeRoy ended third in 23.32.

Bailey, who changed from Glen Mills to her former coach, Lance Brauman, who is based in Florida at the start of the season, says she is now discovering her true form.

"My coach wanted me to double so it could help me with my seasonal progress and so it is a good workout," she said. "I feel good and I am proud of my time and I just have to go back home and start working hard again."

Amazing training partners

With regards to the switch, she added: "The relationship has been going great because I have some amazing training partners, which include Veronica Campbell-Brown, Omar Brown, Tyson Gay and Steve Mullings and they have been pushing me very hard and it has been helping me a lot.

"My goal for this year is to make the World Championships team and finally get my individual gold medal," admitted Bailey.

There were two other world-leading times at the meet.

Jamaica's Novlene Williams-Mills produced a mild surprise to win her pet event, the women's 400 metres, over number-one ranked Jamaican-born Sanya Richards, who now competes for the US. Williams-Mills clocked 50.99, while Richards was timed in 51.12. Williams-Mills' 4x400m relay teammate, Rosemarie Whyte, placed third in 51.85.

The previous world best was 51-flat by American Monica Hargrove.

The other world best also came from a surprise winner Puerto Rico's Javier Culson, who took the men's 400 hurdles in 48.42. Jamaica's Isa Phillips (48.79), American Michael Tinsley (48.81) and Danny McFarlane (48.85) all clocked season-best times in placing second, third and fourth, respectively.

Big favourite for the race, America's Olympic silver medallist Kerron Clement, who holds the meet record of 47.79, finished fifth in 49.10 seconds.

Jamaica's Nickiesha Wilson took the women's equivalent in 55.20 seconds, well off the 54.17 world-best set by American Lashinda Demus in Guadeloupe on Friday night.

"I am really not pleased with the time because my aim was to run in the 54s. But I won and so I guess it is ok," said Wilson, a semi-finalist at last year's Olympics in Beijing, China.

Another Jamaican, Kaliese Spencer, was second in 55.89, while Trinidad and Tobago's Josanne Lucas was third in 56.16. Great Britain's Tasha Danvers, the Olympic bronze medallist, was sixth in 57.15.

Wilson, who finished fourth at the 2007 championships, in Osaka, Japan, also noted that her preparation has been good.

"My season has been going good because I think that my first race went well and to come here and not run better is kind of disappointing, but I will just have to go back and work on my mistakes," said Wilson.

Darvis Patton of the United States sped to victory in the men's 100 in 10.02 seconds. Antigua and Barbuda's Daniel Bailey, who is based in Jamaica as part of the Racers' Track Club, also clocked 10.02 for second, while Jamaica's Yohan Blake finished third in 10.07.

Olympic silver medallist Richard Thompson of Trinidad and Tobago was fourth in 10.19.

In the women's 100 metres hurdles, Olympic champion Dawn Harper of the US won in 12.78, finishing ahead of Jamaica's Vonette Dixon (12.80) and Candice Davis (12.98) of the US, respectively.

Calabar picked up where they left at the Penn Relays, as they clocked 40.66 to win section two of the high-school boys 4x100m relay. St Jago was second in (40.86) and Camperdown third (41.15).

Kingston College took section two in 41.44 ahead of St George's College (41.59) and Herbert Morrison (41.73).
