Mahendra Singh Dhoni once again showed his prowess was not on the wane as he blazed his way to a 34-ball 70 and powered Chennai Super Kings to a five-wicket win over Royal Challengers Bangalore in the Indian Premier League on Wednesday. Opener Ambati Rayudu laid the foundation with a sparkling 82 off 53 balls, hitting eight sixes and three fours. CSK needed 16 runs in the last over and Dhoni hit a six, his seventh of the night, to see his team through after Dwayne Bravo struck and a boundary and a six.
