Eoin Morgan equalled his own record for the fastest T20I fifty for England as he led them to a five-wicket win in a high-scoring thriller delivering a 2-1 series win over South Africa on Sunday. England overhauled the target of 223 with five deliveries to spare thanks to Morgan's unbeaten 22-ball 57 after Jonny Bairstow (66) and Jos Buttler (57) set the base for a grandstand finish at Centurion. <p></p> <p></p>With the series locked at one-all, the third and final T20I served as the series finale and South Africa posted a mammoth 222/6 to set England a stern challenge. The foundation for their strong finish was set by Temba Bavuma whose opening stand with captain Quinton de Kock set them off to a flying start after opting to bat first. <p></p> <p></p>Bavuma scored 49 off 24 while De Kock struck 35 off 24 as they added 84 runs. <p></p> <p></p>The tourists made a sort of a comeback with quick strikes that included the scalps of both the openers and No. 3 Rassie van der Dussen - two of those coming from allrounder Ben Stokes. <p></p> <p></p>Heinrich Klaasen then struck four fours and as many sixes in his 33-ball 66 to put South Africa back on track for a 200-plus total before David Miller applied the finishing touches with an unbeaten 20-ball 35. <p></p> <p></p>England lose opener Jason Roy in the second over but then the pair of Bairstow and Buttler negated the early advantage with their 91-run partnership for the second wicket. Having taken the score past the 100-run mark, Buttler fell in the 10th over. <p></p> <p></p>Bairstow though continued but his departure in the 13th over allowed South Africa to tighten the screws. <p></p> <p></p>With six overs remaining, England needed 76 to win and two new batsmen Morgan and Stokes had just arrived titling the balance little in favour of South Africa. <p></p> <p></p>Morgan changed the equation with some sensational hitting with Stokes assisting him with 12-ball 22. Lungi Ngidi removed Stokes with the first delivery of the 19th over before Morgan hit him for back-to-back sixes to reach fifty off just 21 deliveries. He hit seven sixes in total. <p></p> <p></p>England hit the winning boundary off the first delivery of the final over to finish their successful tour of South Africa.
