Kolkata Knight Riders kept their winning momentum going, knocking Rajasthan Royals out of the IPL with a 25-run victory in the Eliminator at the Eden Gardens here on Wednesday. The Dinesh Karthik-led side will now play Sunrisers Hyderabad in Qualifier 2 on Friday for a berth in Sunday’s final. Much like their last match here, RR once again lost their grip on the match after having the upper hand early on.
