Having won its previous match after two losses upfront, Kolkata Knight Riders (KKR) will look to down Rajasthan Royals in their 4th round match of the IPL-5 at the Eden Gardens in Kolkata later this evening . With a creditable win against a strong Royal Challengers Bangalore, Gautam Gambhir led KKR will also seek to avenge the defeat it faced four days back. Captained by Rahul Dravid, Rajasthan Royals began the season on a wonderful note, winning the first two matches before suffering a defeat at the hands of rampaging Mumbai Indians team on Wednesday. An exciting battle is, therefore, on the cards this evening.
