Jamaica's Briana Williams continued her impressive showing on Thursday in the semi-finals of the Women's 100m at the IAAF U20 Championships in Tampere, Finland.

Running in wet conditions, the 16-year-old Jamaican, exploded from the blocks and cruised home in 11.25s to win the second of three semi-finals heats.

However, unlike in the preliminary round when she had the fastest time, Williams' time was only second best as Twanisha Terry, the American favoured for the gold medal, set a new championship record of 11.03s in winning the first of three semi-finals. It is the seventh fastest ever time run at the U20 level. The American, who has a personal best of 10.99, said her aim was to break the 11-second barrier at these championships and seems on course to achieve that goal.

Great Britain's Kristal Awauh secured her place in the final by winning the third semi-final in 11.37s and looks set to be on the podium after today's final.

TT's Jenea Spinks was third in 11.62 and Jamaica's Ockera Myrie 11.67, were third and fourth, respectively, and failed to advance to the final.
