Omar McLeod brought the smile back to Jamaican sprinting as he powered to the 110 metres hurdles title at the World Athletics Championships in London today.Following the shock defeats of Usain Bolt and Elaine Thompson in the 100 metres events, McLeod, another overwhelming race favourite from the Caribbean island, made no mistake as he added the world crown to the Olympic title he won last year.The 23-year-old dominated the race, winning in 13.04 seconds, a metre clear of the defending champion, Russian Sergey Shubenkov, who was competing as an 'authorised neutral athlete' with his country still banned from international athletics.Other gold medalists were Venezuela's Yulimar Rojas in the triple jump and Poland's Anita Wlodarczyk in the hammer throw.
