England’s outrageous Twenty20 form saw them obliterate Sri Lanka in Manchester, propelling them back to the top of the world rankings in the process.Jos Buttler finished the contest by swatting a one-handed six over midwicket, symbolising the ease with which Harry Brook’s team chased down their 125-run target. They required just 58 of their allotted 120 deliveries.And so with a 20th win in 22 they displaced India in first place, having briefly dislodged the world champions by beating them 4-0 earlier this summer.Neatly, this particular sequence of results began on this ground 12 months ago when England piled up 304 for two against South Africa, the record total between two Test playing nations.’You never want to take the opportunity of whitewashing a side for granted and that’s why we went with our strongest side. We obviously knew we had the chance to go No 1 in this series if we beat them 3-0, so that was always in the back of our minds,’ beamed Brook.’Now, we have got to stay motivated, to try to keep that spot for as long as possible. We don’t play as much T20 as other nations, especially India, so keeping that might not be as easy as it sounds, but every opportunity we get, we are going to try to dominate the opposition.’ Jos Buttler starred for England as they romped to another dominant T20 win over Sri Lanka The team continue to impress under Harry Brook (centre) and are now ranked No 1 in the worldSri Lanka have not defeated England in this format for 12 years and that statistic was not remotely challenged, as they slumped from 107 for four to 124 all out, with the farcical penultimate dismissal of Wanindu Hasaranga – who dislodged the leg bail with a flourish of his bat after missing a delivery from Jofra Archer.Two wickets for Sonny Baker, taking his series figures to six for 44 – at a miserly economy rate of 3.71 – set the tone. Jamie Overton kept up the pressure through the middle overs, sending down 14 dot balls in taking one for 15.And the ruthless nature of this England team was highlighted by Buttler’s finale: in smiting Eshan Malinga for 18 off four balls, including his only two sixes of the innings, he finished unbeaten on 62 off 32.Sri Lanka crumbled under the pressure, allowing Brook to get off the mark via a misfield. He departed to a run out, after adding 33 from 21. It felt like the only way Sri Lanka would dismiss him such was the disdain with which he treated their bowlers.
