American Kelli White was crowned the fastest women in the world after claiming the 100m gold medal at the World Championships in Paris.
The 26-year-old, who won bronze two years ago, burst away from the pack at the 50m-mark to win in 10.89 seconds - the fastest time of the year.
American number two Torri Edwards made the most of a strong start to hold on for the silver medal in a personal best of 10.93.
Defending champion Zhanna Block battled to the line to take bronze, finishing a season blighted with injuries on something of a high note.
"This is the beginning," said White. "We can all have one successful season but it's doing it over and over that makes a successful champion.
"I don't have to be world champion again or Olympic champion but I would like to be consistent."
White will now attempt to emulate American sprint queen Marion Jones, who missed the championships after giving birth to a baby son, by going for multiple medals in Paris.
"It has not really sunk in yet, as I'm thinking about the 200m," White revealed.
"I also have the 4x100 relay to think about as well. The meet's not over yet so I can't do much tonight."
Block added to her world gold and silver medals with a bronze and was delighted to recover from a thigh injury to grab a spot on the podium.
"Every athlete feels they deserve the gold but White definitely deserved the title," said the 31-year-old Ukranian.
"If I was healthy I would have given her a better race, but injury is a part of our job.
"I did everything I could in the last 10 weeks to stay fit, get treatment and get better. I was probably a couple of weeks short of preparation."
Bahamian sprinter Chandra Sturrup, who had gone into the race as the world's number one female sprinter, was forced out into fourth place while Olympic silver medallist Greece's Ekaterini Thanou came home fifth.
