Rajasthan Royals defeated the former champions Chennai Super Kings by 14 runs in an exciting finish to qualify for the final of the Champions League Twenty20 (CLT20) 2013 tournament on Friday.

Rajasthan posted a competitive 159 for eight, courtesy a 56-ball 70-run innings by opener Rahane, after they were sent into bat by Chennai skipper Mahendra Singh Dhoni, PTI reported.

The hosts then rode on a sensational spell of spin bowling by Pravin Tambe (3/10) to restrict the Super Kings to 145 for eight and register their 13 victory on a row at the Sawai Mansingh stadium.

Lower-order batsman Ravichandran Ashwin blasted a quickfire 28-ball 46, studded with three fours and as many sixes, to give some hope to the Chennai side in the last stages of the match but it was not enough in the end.

Defending 159, Rajasthan were athletic on the field while Chennai looked sloppy in their running between the wickets and it cost them their first two wickets.
