A struggling Kings XI Punjab will have to pull out all stops against the sole unbeaten side, Rajasthan Royals, when the two teams clash in an Indian Premier league match here on Tuesday. Rajasthan Royals have successfully dealt with all the challenges thrown at them in the five games they have played so far. Four of those wins have come while chasing, with the one here on Sunday against a consistent outfit like Chennai Super Kings, being the most convincing.
