Root has taken England 'beyond par' - Vaughan

Joe Root's century on day one of the second Ashes Test has taken England to an above-par score in the first innings, says former captain Michael Vaughan.

Root scored a sensational 135 not out to keep England afloat in Brisbane and ensure they reached 325-9 at the close.

Having come in at 5-2, Root put on 117 with Zak Crawley, 54 with Harry Brook and then crucially 61 unbroken with Jofra Archer for the final wicket.

While the average first-innings score in day-night Tests in Australia is 346, that drops to 295 in the three Tests held at the Gabba.

"England can't win without him," Vaughan said.

"He has got England to that 325 score. It is beyond par on that wicket with the pink ball."
