England have tightened their grip on the first day-night Test against the West Indies after Alastair Cook registered a remarkable 243 on day two.
The 32-year-old, England's leading run-scorer of all time, accumulated the third-highest Test score of his career in nine hours and 22 minutes at the crease.
Cook ended up hitting 33 fours off 407 balls, his eventual dismissal at the hands of Roston Chase prompting England's declaration at 514-8 before tea.
Meanwhile Dawid Malan, looking to secure a place at number five, scored 65, his maiden Test half-century.
West Indies had reached 44-1, 470 behind, when rain forced the players off with 26 overs left to bowl.
