By any measure, this was an incredible day of Test cricket, one that broke new ground and challenged other landmarks that have stood for decades.

Even on a pitch that has been abnormally flat for the best part of four days, and against a toothless Pakistan attack missing ill spinner Abrar Ahmed, the runs scored by Brook, Root and England were extraordinary.

The tourists gave themselves the advantage by moving to 492-3 on day three, when Root became England’s all-time leading Test run-scorer.

Root had added 10 to his overnight 176 when he drilled Naseem Shah to mid-wicket, where Babar Azam shelled a simple catch. From there, Pakistan fell apart, England scored at will and the prospect of a rare triple-century quickly became a reality.

Brook, resuming on 141, went past his previous highest Test score of 186. A top-edge off Aamer Jamal just evaded the square leg fielder and, from the next ball, a Brook pull took the stand past England’s previous best partnership of 411 between greats Colin Cowdrey and Peter May in 1957.

Root found another best in his record-laden career, beating his previous highest score of 254. After 10 hours at the crease, he was eventually beaten by an off-break that Salman Agha got to keep low.

Brook went on and on, toying with the bowling using both classical and unorthodox strokes: cover drives, ramps, flicks and use of the feet. Pakistan became a rabble, beset by misfields and overthrows, while six home bowlers conceded more than 100 runs.

Only eight overs were needed to add 79 with Jamie Smith. Brook went from 250 to 300 in just 29 balls, a holy grail of batting achievements reached thanks to a straight four off Saim Ayub.

It was the 32nd instance of a triple century in Test cricket, which Brook celebrated with a salute to the dressing room and a look to the sky.

The 25-year-old seemed set to challenge Sir Len Hutton’s 364, the highest score by an England batter, until he top-edged a sweep off Ayub. He left owning the fifth-highest score by an Englishman.

Still England were not done, becoming the fourth team to pass 800 before captain Ollie Pope decided enough was enough just before tea.
