The superb opening burst from Makhaya Ntini and Manpreet Gony reduced Mohali to 34/4 in 6 overs. The change bowlers Morkel (2/27) and Balaji continued the good work with a probing line to limit the Mohali outfit to 112/8. Wily Murali, who started the proceedings for Chennai, too joined with an economical spell besides plucking the wicket of Piyush Chawla.
No. 9 batsman Ramesh Powar swung the bat to good effect to take Mohali past 100. Shaun Marsh (23 off 17), a run-machine, failed to deliver the goods for Mohali in the crunch game. Right-arm seamer Wilkin Mota coming in for Luke Pomersbach made a sedate 25.
In reply Chennai hunted down the measly target with nine wickets in hand and as many as 31 balls to spare. Parthiv (51*) and Raina (55* off 34) shared an unbeaten 102-run stand for the second wicket.
Parthiv dealt in boundaries hitting eight of them in his 48-ball knock while Raina feasted on the tossed up deliveries from Powar and Chawla belting four sixes and as many boundaries.
Vidyut's wicket was the sole consolation for the Mohali Kings as the two young left-handers batted elegantly and sensibly to steer their side to final.
Chennai take on the spirited Warne boys in the garnd finale to be held at the D Y Patil Stadium, Mumbai on Sunday.
Everything went wrong for Kings XI Punjab after captain Yuvraj Singh opted to bat first on winning the toss and half their side was back in the dug-out with only 40 on the board on a seamer-friendly track.
Thoughtless batting and running between the wickets coupled with some good seam bowling and sharp catching undid the Punjab side.
Makhaya Ntini and Manpreet Singh Gony wrecked the high-flying Kings XI Punjab side with a double strike apiece which reduced Yuvraj-led team to a pathetic 34 for four in the sixth over.
Ntini started the rot when he had James Hopes caught behind chasing an outswinger for two in the second over.
Then Gony dismissed Sangakkara in similar fashion, caught by gloveman Parthiv Patel to leave Punjab at a shaky 11/2.
Gony, who bowled his four overs on trot, removed Yuvraj when the southpaw pulled straight to Murali at mid-wicket to leave Mohali in a spot of bother at 28/3 in fifth over.
In the following over Ntini sent the dangerous Shaun Marsh packing when the left-hander from Western Australia played an outside the off-stump delivery onto the stumps.
Irfan Pathan came and went in a jiffy. Pathan was dismissed for a reckless run out. Mahela cuts Gony over point and the batsmen scamperd for two runs and Pathan ran for the third while Mahela was content with two. Ntini's throw from the backward point fence defeated the Baroda all-rounder.
Jayawardene followed Pathan immediatly edging a short of length ball on off-stump line from Morkel for a regulation caught-behind.
Wilkin Mota, Chawla and Powar got into damage control act and ensured their side reach three-figure mark.
