RR won the toss and choose to bowl.It is big match for the RR because they need to win most of the matches as they can to enter into the playoffs.RR is much weaker side in my opinion because last match is very easy to win for them and the captain is at the crease but he still can't even hit the balls at the last overs such an poor form from them.
Rain has delayed the start of the match and already an hour has passed and match has not yet started. So RR has already now have an upper edge because match could be of less overs and if it rain again in between match RR will have more wickets in less overs to bat.
