On yesterday's final day men's national junior 110 metres hurdles record holder Keiron Stewart, snatched the bronze medal in 13.51 seconds, the same time as Saudi Arabia's Sami Ahmed Al-Haydar.

Stewart was a happy man with his bronze, despite concerns about the weather. "Mentally, I was prepared for anything, rain, cold ... I just came out to do my best ... World Junior final, any medal is good," he said.

Russian Konstantin Shabanov won the event in a world junior leading 13.27 seconds ahead of American Booker Nunley 13.45.

Meanwhile, Williams took silver in the women's 100m hurdles in 13.48 seconds behind American Teona Rodgers (13.40) on Saturday.

Hamstring injury

Williams was also happy with her medal: "I am feeling good ... I could have finished without a medal, so I am thankful," she said.

Natasha Ruddock, Jamaica's other entry, did well in overcoming a hamstring injury to finish sixth in 13.70.

"I am just happy that I completed the final," said Ruddock, who hinted things would have been different if it wasn't for the injury.

In the women's sprint relay, the quartet of Shawna Anderson, Kaycea Jones, Gayon Evans and Jura Levy executed well for second in a season-best 43.98 behind the United States, who won in a world-leading 43.66.

Coach Michael Dyke, who was in charge of the team, said a lot of work was put in with the girls.

"I know it was a little bit shaky, but we tried all the different combinations, so I decided to keep the three Edwin Allen girls (Anderson, Jones and Evans) together and put Jura with the extra speed at the end, I knew we would win a medal," said Dyke.

In the boy's event, Oshane Bailey, Dexter Lee, Nickel Ashmeade and Yohan Blake took Jamaica to second in a season-best 39.25. The US took gold in a world-leading 38.98.
