Markus Rogan, of Austria, felled Ryan Lochte by 0.07sec in the 200m backstroke as the two men shattered the previous world record at Manchester 2008, the difference 1:47.84 to 1:47.91, their pace slugging Lochte's 2006 best of 1:49.05 into a bygone age.
Here's how the battle unfolded:
The bronze went to Stanislav Donets (RUS) in 1:50.45.
Rogan noted that his previous best had been left three seconds behind. 'That's Ryan's fault. He dragged me along. I can't go [that fast] by myself but with him I can. I wanted to take off at the 100(m) and it didn't work. He's annoying!'
