2015 World Championships in Athletics – Men's 110 metres hurdles

The returning champion was David Oliver, while world leader in 2015 Orlando Ortega is ineligible after switching his nationality to Spain (after defecting to the USA at the 2013 Championships). World record holder Aries Merritt was here, just days before a scheduled kidney transplant.[2][3]

The heats will be remembered for the false start disqualification of Ronnie Ash. Similar to Jon Drummond's incident in 2003, Ash refused to accept the disqualification and took several minutes before being convinced to leave the track.[4]

In the finals, Oliver was the first to the first hurdle, and he hit it badly. Dimitri Bascou was the next to show a microscopic lead which only lasted until he clobbered the third hurdle, giving world #2 Omar McLeod three steps in the lead until he flipped the fourth hurdle. Merritt and Sergey Shubenkov were the next leaders. Merritt seemed to be running too close to the hurdles and had to slow to compensate giving Shubenkov a slight edge. Hansle Parchment built up speed and even though he hit the tenth hurdle, had more speed to the finish.[5] His late rush passed Merritt to earn silver and make for a challenge to Shubenkov for the gold. Shubenkov's 12.98 was a new Russian National Record.[6]
