WORLD Athletics Championships 4x400 metres silver medallist Deijanea Oakley was on fire last Saturday on the final day of competition at the Southeastern Conference Track and Field Championships at Auburn University as she raced to a world-leading and personal-best 48.92 seconds to win the women’s 400 metres.

Representing the University of Georgia, Oakley, who was fourth in the event last year, crossed the line well ahead of the field as Kaylyn Brown of the University of Arkansas was second in 49.54, with her teammate Sanaria Butler third in 50.22.

The 21-year-old Oakley, who captured the indoor title in the event at last year’s NCAA Division I Indoor Track and Field Championships and was runner-up at the outdoor championships, became the second-fastest Jamaican ever in NCAA history and, in the process, replaced Nigeria's Ella Onojuvwevuc previous world best of 49.59.
