Jordan Spieth says pars won’t do as ‘monster’s’ defences left vulnerable

Old man par is usually your friend at the US Open but Erin Hills is such an unknown quantity that the world’s best are hedging their bets on the winning score this week.

The first par-72 course to stage a US Open since Pebble Beach in 1992 is a veritable monster, measuring 7,741 yards from the back stakes with deep fescue rough lining both sides of every fairway.

But with heavy rain taking the still out of its billowing fairways, little wind forecast and the greens more receptive that in previous years, 2015 champion Jordan Spieth sees the winner getting well into the red.
