After restricting Kings XI Punjab to a none too impressive 130 for seven in 20 overs, CSK pair of Faf du Plessis (55, 41 balls) and Suresh Raina (41 no, 34 balls) added 92 runs for the third wicket to lay the foundation of a victory that was achieved in 16.5 overs.
Du Plessis and Raina joined forces after CSK were put in a spot at 10 for 2 with both Mike Hussey (1) and Brendon McCullum (6) being dismissed cheaply.
Finishing on top of the table ensures that CSK will be playing the first qualifier and even if they lose will get another shot at summit glory facing the winner of the 'Eliminator' between teams placed third and fourth.
For Kings XI Punjab, it was the end of a rather forgettable season, where nothing went right for them. Last year's champions finished their campaign with six points from 14 encounters, losing 11 matches in all.
Despite not hitting too many sixes, the Du Plessis-Raina duo scored the runs at a fair clip in only 11.3 overs before the South African was cleaned up by Rishi Dhawan.
CSK by then nearly pocketed the match and it was left to skipper Mahendra Singh Dhoni (25, 16 balls) to complete the formalities with some lusty hits.
