Jones impresses in 100m hurdles heats as day four kicks off in Bydgoszcz

Tia Jones finished second at the US Junior Championships last month but the 15-year-old, who has already clocked 12.84 in the 100m hurdles and still has three full seasons left in the junior ranks, was the fastest qualifier across the six heats, the key highlight as the fourth day of competition at the IAAF World U20 Championships Bydgoszcz 2016 got underway on Friday (22).
