Rajasthan Royals will take on Mumbai Indians in Kolkata tomorrow in the Qualifier Two match of the IPL tournament. The encounter will begin at 8 P.M. On paper, Mumbai Indians may appear stronger but Rajasthan will be high on confidence after their four-wicket win against Sunrisers Hyderabad yesterday in the Elimanator fixture. Tomorrow's match will determine the Chennai Super Kings' opponents in the Sunday summit clash at the same venue.
