Chennai bowlers put up a good show to help their side register a comfortable 55-run victory against Kolkata at Eden Gardens.
Justin Kemp dismissed two wickets of hosts Kolkata in quick succession as he packed off Angelo Mathews and Rohan Gavaskar.
Muralitharan followed soon by claiming the eighth one in Laxmiratan Shukla. R Ashwin then accounted for the penultimate wicket in Shane Bond. Murali Kartik was the last one to get run out.
Justin Kemp accounted for the fifth Kolkata wicket in skipper Sourav Ganguly as Morkel took the catch at deep midwicket.
Albie Morkel and Manpreet Gony struck early to rock Kolkata's ship as the hosts started their 165-run chase on a dismal note.
Ashwin caught Brad Hodge off Morkel to land the first wicket. Gony then accounted for Manoj Tiwary to deal another blow.
Then Laxmipathy Balaji got the better of Wriddhiman Saha's middle stump to send the third one packing.
After that Dhoni did a neat job behind the stumps to help Balaji land his second wicket in Owais Shah.
Skipper MS Dhoni and Subramaniam Badrinath brought Chennai back into the fray after Kolkata dealt them quick successive blows. Dhoni hit a half-century (66) and Badrinath also contributed 43 runs to lead Chennai to 164/3.
Brad Hodge accounted for the third Chennai wicket in Suresh Raina.
Murali Vijay was the second batsman to depart when Laxmi Shukla got the better of his stumps.
Chennai lost an important wicket in Matthew Hayden as Ishant Sharma dismissed him as soon as he got off the mark.
Chennai skipper MS Dhoni called right at the toss and chose to bat first against Kolkata at Eden Gardens.
With back-to-back victories, Kolkata must be raring to go against Chennai in their IPL match today.
His decision to promote Virender Sehwag to the opening slot had made history, a benchmark for a captain's thinking ability. Now Sourav Ganguly is at it again. He is trying to do the same with Manoj Tiwary. For Sehwag, it was in the longest version of the game and for Manoj, it is in the shortest version.
But the impact is the same! Manoj, too, had never opened in his entire cricketing life except on one or two club matches, before he was instructed to do the same for Kolkata by Sourav.
Kolkata: Sourav Ganguly (C), Brad Hodge, Manoj Tiwary, Owais Shah, Laxmi Shukla, Rohan Gavaskar, Angelo Mathews, Wriddhiman Saha (W), Murali Kartik, Ishant Sharma, Shane Bond.
