Needing to win to stay afloat in the tournament, Kings XI made a wobbling start after they being put in to bat but made a late recovery to put up a respectable total.
After two back-to-back wins, Kings XI Punjab will play against Gujarat Lions at Mohali.
Tewatia's twin strikes in the 10th over wherein he accounted for struggling Gambhir (8, 18balls) and Robin Uthappa (0), knocked the wind out of KKR's sails. The pick of the KXIP bowlers was Rahul Tewatia who took 2 wickets for 18 runs from his 4 overs while Mohit Sharma got 2/24 from 3 overs.
Then Chris Lynn, who diagnosed himself "not 100 per cent fit" before the game, took on the unsafe Punjab spearhead bowler Sandeep Sharma and hit him for three fours in the first over to take the fight to the opposition. KKR with 16 points is second placed on the points table with a better run rate than Rising Pune Supergiants. In the 20 matches played between the two teams, Kolkata have won 14 and lost just six. Lynn and Manish Pandey (18) stitched together 52 runs (44 balls) in a fourth-wicket stand, but once this stand was broken - both falling in the 18th over - it was all but over for the visitors. The first went for 14, the second for 11 and three overs in, Kolkata were already sitting comfortably at 31/0.
Narine hit two boundaries off Sandeep Sharma's first two balls of the first over to announce his intentions while Lynn too hit a four in the same over to join the party.
KKR were 82 for 3 at the halfway stage, needing another 89 to win the match.
Amla has smashed the perception that he is a long format player as he hit 104 off 60 balls to power the Kings XI Punjab to 189 in their 20 overs.
Dwayne Smith struck a whirlwind 74 as Gujarat Lions defeated Kings XI Punjab by six wickets in an Indian Premier League game, here on Sunday.
In the absence of Hashim Amla, Martin Guptill opened the batting with Manan Vohra. The opener had raced to 41 from 19 balls and KKR were 61-1 at the end of the powerplay period.
Due to the fact that the third and fourth-placed teams are in a do-or-die situation from match one, it becomes really important to finish in the top two, because those two teams get is one more opportunity at making the final, and that is something that can not be taken lightly.
But Yadav had the last laugh as he dismissed Vohra in the fifth over with his short delivery kissing the batsman's gloves for Robin Uthappa to do the rest behind the stumps.
In the next over, Narine got Guptill (12; 16b 1x4 0x6) leg before wicket.
