Kolkata Knight Riders to keep their spin attack in the kit

THE Indian Premier League's reigning champions, the Kolkata Knight Riders, are tipped to be hard to beat again in this year's ninth edition of the tournament.

The Knight Riders will begin their new campaign against the Mumbai Indians at Eden Gardens tonight.

Spin has played a key role in the success of the Knight Riders, which also won the title in 2012, with the mystery of West Indian Sunil Narine (pictured) befuddling many batsmen.

Perth Scorchers veteran Brad Hogg and young chinaman bowler Kuldeep Yadav can also chip in.

Last year's runners-up, Kings XI Punjab, will have Aussie excitement machine Glenn Maxwell in prime form following his World Cup fireworks, including a 53-ball 102 against Sri Lanka.

That team will play the Rajasthan Royals on Friday, while Mike Hussey's Chennai Super Kings take on the Delhi Daredevils tomorrow.
