We don't know what gonna happen in the upcoming matches. In tomorrow's play off any sort of changes could happen, because in the last few matches Mumbai Indians performance is not that good. UP Warriorz seems like improving and for this reason I find the finals to take place between Delhi Capitals and UP Warriorz.
Mumbai won their last match, so we can't say that the momentum is not with them (although they had consecutive losses before that, to Delhi Capitals and UP Warriorz Women). On the other hand, their opponents have also lost 3 out of their last 5 matches. On paper Mumbai looks extremely strong. As with the men's version of the competition, Mumbai always get the best players. And this time they have Harmanpreet Kaur, Yastika Bhatia, Hayley Matthews, Issy Wong and emerging players like Saika Ishaque. On the other hand, UP Warriorz Women are very dependent on their overseas players - Alyssa Healy, Grace Harris and Sophie Ecclestone.
