Kyron McMaster almost failed to put his talent on full display on the world stage for the second major meet in a row after he was disqualified from the 400 metre hurdles in Doha, Qatar for a hurdles infringement, only to be re-instated later.

McMaster, one of the five or six best 400 hurdlers in the world at this point, seemed to want to make a statement in his semi-final heat on Saturday and stormed out of the blocks so quickly he slammed into the first hurdle and almost did not recover.

The US Virgin Islands athlete still managed to finish third in the heat, clocking 48.40 behind the fast finishing Brazillian Alison Dos Santos, 48.35, and Turkey’s Yasmani Copello, 48.39.

McMaster had initially been labelled with a disqualification but successfully appealed the decision.

In a previous World Championships, McMaster, then the quickest in the world with some mid-47-second runs, failed to negotiate a hurdle properly and was deemed to have breeched the same rule. On that occasion there was to be no reversal.

In the meantime, McMaster’s rivals over the distance have all made it to the final.

Karsten Warholm, the man who has gone fastest this year and is the second fastest 400 hurdler in history won his heat comfortably in 48.28, while Rai Benjamin showed he was in better shape than Abderrahman Samba, beating the former world number one to the line in 48.52. Samba would stop the clock at 48.72.

The other man from the Caribbean in the event, Jamaica’s Kemar Mowatt, struggled in the semi-final, finishing seventh in 49.32 to bring an unwelcome end to his World Championships experience.

Once again, Abderrahman Samba stole the Diamond League spotlight with another superb performance to highlight the IAAF Diamond League Shanghai on Saturday (18).

Already in the spotlight as the key protagonist in the meeting’s most eagerly anticipated face-off, Samba lived up to expectations with a decisive victory over Rai Benjamin in the pair’s first head-to-head battle.

Running to the Qatari’s outside in lane five, Benjamin, son of former West Indies fast Bowler Winston Benjamin and the third fastest 400m hurdler of all-time, took the early lead, leading Samba, history’s second-fastest ever, by about half a stride until the pair reached the fifth hurdle. Samba briefly pulled ahead, but Benjamin kept up the pressure through the turn as they approached hurdle nine. There, Benjamin lost his rhythm, giving Samba an opening he took full advantage of. Three strides later, Samba was in the lead for good, padding his advantage as he cleared hurdle ten before crossing the line in 47.27, the second fastest time of his career in just his second race of the season. And he did it on less than a handful of restless hours or sleep after losing a battle with jetlag.

“To be honest with you, I couldn't sleep last night,” Samba said. “I fell asleep this morning at about 7 and got up at 10:30. But I’m so happy. It’s my second fastest time so I think the season will be great again like last year.” It was his 12th straight victory.

Only eight other men have ever run faster, Benjamin, who clocked 47.02 last year, among them. Despite his late-race dip in fortunes, the 21-year-old was pleased.

“I was good until (hurdles) 9 and 10 - I wish I could have those hurdles back - but it's fine, it's the season opener so I can't really complain too much,” said Benjamin, whose 47.80 run was also the second fastest of his career. “I didn't go out too strong, he just had it at the end and I didn't. I just have to go home and work on some things and come back.”

The tenth anniversary season of the IAAF Diamond League continues with the Diamond League Shanghai meeting on Saturday whose programme includes a slew of tantalising head-to-heads that just may define much of the 2019 season in the run up to the IAAF World Athletics Championships Doha 2019. 

Rai Benjamin, one of the fastest men in history in the 400m hurdles is officially a USA athlete.
