South Africa allrounder Albie Morkel plundered 28 runs off an over from Virat Kohli as Chennai Super Kings scored a thrilling last-ball victory over Royal Challengers Bangalore in the Indian Premier League on Thursday. Defending champion Chennai seemed to have been edged out when it needed 43 off the last two overs, but Morkel (28) turned the game around in the 19th over with three sixes and two fours, leaving allrounders Dwayne Bravo and Ravindra Jadeja to complete a five-wicket win. Bangalore had scored a mammoth 205-8 as opener Chris Gayle (68) led a belligerent top-order performance. But Chennai remained in the hunt through South African Faf du Plessis (71 off 46) and Mahendra Singh Dhoni (41 off 24) before the allrounders wrapped up the game at 208-5.
