This was the first time the event was held at a World Championship level meet.
In the first leg, Australian Ryan Gregson took it out in 2:53.15 to take a 5-meter lead over American Kyle Merber with Kenya another 7 meters back.
The 800 metre leg was thrilling as Brandon Johnson quickly passed Jordan Williamsz only to be overtaken by Ferguson Cheruiyot Rotich.
But Ben Blankenship had no interest in the lead, literally slowing down and inviting Timothy Cheruiyot to take over.
Cheruiyot more than obliged, accelerating to a much faster pace breaking away from Blankenship possibly trying to steal the race while Collis Birmingham brought Australia back into the mix.
