The New Zealand side are placed second with 10 points and a win will ensure them a last-four spot, putting Mumbai Indians out of the tournament.
Mumbai and Otago’s fate will depend on net run-rate if the Kiwi side are defeated and the IPL champions beat Perth Scorchers on Wednesday.
Otago pipped Highveld Lions in the Super Over on Sunday. Both teams scored 13 runs in the over but Otago won by virtue of losing no wickets compared to Lions two.
On the other hand, a win today will guarantee a top place finish for the Royals in Group ‘A’. This will also ensure that they play their semi-final at home on Friday.
Rajasthan went to the top of the group courtesy a nine-wicket win over Perth on Sunday.
Chasing a modest target of 121, the Royals won their third consecutive match with 3.3 overs to spare as opener Ajinkya Rahana (62 not out) and wicketkeeper batsman Sanju Samson (50 not out) guided the team home.
