But despite Thursday's sublime scoring taking many by surprise, almost 60 per cent of those who responded to this week's iSeekGolf Weekly Reader Poll predicted an under par winning total.
With Rickie Fowler at 7 under through 18 holes and a further 43 players in red numbers after day one, an under par champion appears a foregone conclusion.
The largest group of respondents (29 per cent) said this week's winner will finish at 3-4 under par, while the next largest group (24 per cent) conversely forecast a leading mark of three over or worse.
But a telling fact was that 59 per cent of poll voters anticipated the 2017 US Open champion will finish under par.
