The MumbaiIndians put their off-field troubles aside and pulled off their first win, a 7-wicket victory over Kolkata Knight Riders in an Indian Premier League encounter here Tuesday. Thanks to Sanath Jayasuriya's 3 for 14, the best figures of the tournament, Mumbai restricted Kolkata to 137-8 in the allotted overs. Mumbai had a nervy start and was 25-3 before Dwayne Bravo and Robin Uthappa put on a century stand to take the total past 100. Despite the below-par score, Kolkata refused to surrender and took some early wickets. Uthappa and Bravo, however, carried the team to victory with a century stand for the fourth wicket. Scores: Kolkata Knight Riders - 137 for 8 (Shukla 40*, Jayasuriya 3-14); MumbaiIndians - 138 for 3 (Bravo 62*, Uthappa 37*).Clarke plays down T20 talk England and Wales Cricket Board (ECB) chairman Giles Clarke dismissed on Tuesday talk of a city franchise system being introduced for domestic Twenty20 cricket. Clarke, speaking at the ECB's annual general meeting at Lord's, said fan loyalty was an important part of all sport in Britain and would have to be a factor in any attempts to emulate a new domestic league in India. “Franchise sport has simply never worked in the UK,” he said. “Tradition and history rather than Bollywood stars and glitz are the binding which persuade supporters to return week in, week out to our grounds - whether it is rugby, football or cricket,” the former Somerset chairman added.
