This total should be chaseable, but with Royal Challengers' batting having failed miserably on two successive occasions, they would still exercise caution as they go about chasing these runs down.
The lowest total successfully defended this year has been 131, and that was by Kolkata Knight Rides when they shot out Bangalore for the lowest total in IPL history. Those wounds are still fresh. Remember, they need to win all their remaining games. Another defeat could almost certainly spell curtains for them. Be back shortly with the chase.
