Defending women’s champion Shaunae Miller-Uibo, five months removed from the birth of her first child, failed to advance to the semi-final round of the 400m at the 2023 World Athletics Championships in Budapest, Hungary on Sunday.

The Bahamian star finished seventh in Heat 3 in 52.65. The 2022 bronze medallist Sada Williams of Barbados won the heat in 50.78 to keep her quest alive for another global medal in the one-lap sprint.

Meanwhile, all three Jamaicans advanced to the semi-final round of the competition. Jamaican champion Nickisha Price comfortably won Heat 4 in 50.38 over Cuba’s Roxana Gomez, who eased to second place in 50.86 and Gabby Scott of Puerto Rico, who was also an automatic qualifier, finishing third in a season’s best time of 51.07.

Candice McLeod was third in the opening heat in 50.37 to earn her place in the semi-final round. That heat was won by medal favourite Natalia Kaczmarek of Poland in an impressive 50.02. Cynthia Bolingo of Belgium ran a season’s best 50.29 to advance.

Charokee Young, meantime, sneaked into the next round as one of the sixth fastest finishers, when she ended up sixth in the sixth and final heat won by gold medal favourite Marileidy Paulino of the Dominican Republic in a smart time of 49.90.

Young struggled to a time of 51.24.

Guyana’s Aliyah Abrahams was not as fortunate. She ran 51.44 to finish fifth in Heat 5 and failed to advance. Ireland’s Rhasidat Adeleke, who recently signed a professional contract, won the heat in 50.80.
