R Ashwin, Suresh Raina humble Kolkata

Chennai Super Kings 143 for 1 (Raina 78*, Vijay 50*) beat Kolkata Knight Riders 139 for 8 (Mathews 48, Ashwin 3-16, Bollinger 2-15 ) by nine wickets

Chennai Super Kings, inspired equally by crushed a scruffy Kolkata Knight Riders by nine wickets in front of a throbbing, partisan home crowd. After Ashwin, who for the second consecutive game grabbed two wickets in an over, led the attack in keeping Kolkata to a paltry 139 for 8, Raina and M Vijay launched a powerful assault to see Chennai home with 6.2 overs to spare and propel them to second place in the points table.

The unbeaten stand between Raina and Vijay raised the fastest team hundred of the IPL and the pair made the same surface, on which Kolkata struggled, appear a concrete strip. With another disappointing performance Kolkata are now perilously close to being knocked out.

In a crunch game, Ashwin took the new ball and rocked the top order during a mesmerising spell after Sourav Ganguly opted to bat on a surface he reckoned would assist spin later in the night. The first over suggested spin would play a role quicker than that, but at 11 for 0 after two overs Ganguly couldn't have envisioned what lay in store.
