Harry Brook led from the front with his second and fastest T20I century as England sent Sri Lanka swirling down the Utilita Bowl with victory by 119 runs in the first T20I.

The limited-overs skipper's 42-ball effort - quicker than every Englishman bar Phil Salt's 39-baller almost a year ago to the day against South Africa - took England to 254 for 4, compelling former Test captain Ben Stokes to wax lyrical on social media.

Stokes' post sounded as confused as Sri Lanka's bowling plans. But the underlying sentiment was that Brook's unbeaten 114 showed he possesses more genius than Kevin Pietersen.

It is a sketchy claim. But perhaps tonight, England's new mentor will happily cede to the 27-year old after his third white-ball century of the year, and second in T20Is after his maiden effort against Pakistan at the T20 World Cup. In reply, Sri Lanka mustered just 21 more than Brook's new career-best between them, bowled out for 135 with an over to spare.

England's first innings fell three runs short of the total they made in their last T20I against India, on this very ground. The similarities between this evening and that July afternoon included the opposition skipper - on this occasion, Charith Asalanka - inserting England after winning the toss.

Shreyas Iyer had made that mistake two months earlier, and likewise, he was also made to pay by Brook and Jos Buttler, who this time had to settle for 80 from 44 deliveries, rather than consecutive hundreds.
