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 made a 42-ball effort, faster than any Englishman except Phil Salt, who made a 39-ball effort almost a year ago to the day against South Africa. This brought England's score to 254 for 4, which prompted Ben Stokes, a former Test captain, to wax lyrical on social media. Stokes' post sounded as confused as Sri Lanka's bowling plans. However, the overarching sentiment was that Brook's 114-match unbeaten streak demonstrated his superior intelligence to Kevin Pietersen. It's a questionable 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. Sri Lanka, on the other hand, managed just 21 runs more than Brook's new career high and was bowled out for 135 with one over remaining. 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. Captain and former captain combined in a stand of 128 from 60 deliveries, the first part of which included England's second-highest powerplay of 90 for 1. That started with an easy 12 from 5 for debutant Aneurin Donald, who became the first Glamorgan player since 2005's Simon Jones to play for England. Things were getting away from Sri Lanka as early as the fifth over when Dunith Wellalage was taken for 30 by Brook. It was abundantly clear, not even a quarter of the way through the match, that this match was only going in one direction when Buttler was run out on 45 three overs later by Eshan Malinga for overrunning a sliced heave down the ground at long off. England's superior fitness and power could never be matched. Their number of twos was even more impressive than their total of 19 fours and 12 sixes. Brook did most of the running; nine of his own along with 12 for his three partners. Sonny Baker bowled Sri Lanka's maiden, which was followed by his 3 for 12 score. The 23-year-old polished his overall numbers with his first dismissals in limited overs at his home ground after struggling on debut across all three formats, including a Test debut earlier this summer against New Zealand. The Hampshire quick got off the mark with a 90mph rasper that beat opener Kamil Mishara, before adding Lahiru Udara four deliveries later when the right-hander's attempted scoop found Adil Rashid at short backward square. A return from the Pavilion End then saw a 92mph delivery nip away and knock back Theekshana's off stump. All six of England's bowlers registered in the wicket column, feasting on a line-up that - barring Wellalage's 33 from 21 at No.8 - were all utterly woeful.
