She won her first individual gold medal at the 2001 World Championships – having initially won silver, gold medallist Marion Jones was later disqualified.
The 2002 season was a career high for Ferguson-McKenzie: she won five gold medals, with victories at the IAAF World Cup and Grand Prix Final, and a 100 m, 200 m and relay gold at the 2002 Commonwealth Games. Her performance in the 100 m remains a personal best and Commonwealth Games record, and her time in the 200 m was the fastest by any athlete that year. She won her only individual Olympic medal in 2004, taking bronze in the 200 m. Injury ruled her out for the whole of 2005. She failed to reach the finals at the 2007 World Championships, unable to compete with the new generation of American and Jamaican sprinters. However, she managed to reach the 100 and 200 metres finals at the 2008 Beijing Olympics.
She is the current 200 m national record holder with a best of 22.19 seconds. Her 100 m best (10.91) is the second fastest time by a Bahamian after Chandra Sturrup.
Ferguson attended St Andrew's School in Nassau, Bahamas and graduated in 1994.
Ferguson graduated from University of Georgia from where she launched her senior athletics career since which she has gained medals at the Summer Olympics, IAAF World Championships in Athletics, Commonwealth Games and Pan American Games.
In 2002 she was appointed as an ambassador for the United Nations Food and Agriculture Organization. At the 2002 Commonwealth Games in Manchester, England, she set the championship record in the 100 metres and in the 4×100 m relay with the Bahamian team, recording a personal best of 10.91 seconds in the individual event.
At the 2008 Summer Olympics in Beijing she competed at the 100 metres sprint. In her first round heat she placed second behind Oludamola Osayomi in a time of 11.17 to advance to the second round. There she won her series to qualify for the semi finals in a time of 11.21, this time finishing in front of Osayomi. Despite fellow Bahamian Chandra Sturrup being unable to qualify for the final with a time of 11.22 in the first semi final, Ferguson managed to qualify with the same time as she finished fourth in her race, while Sturrup finished fifth in hers. In the final Ferguson came to 11.19 seconds, which was the 7th position.
