Warriorz have made the playoffs on the back of a strong middle-order display. Of the 1161 runs Warriorz have scored, 663 have come from the middle order (Nos. 4 to 7), the most in the WPL. Tahlia McGrath and Harris have made the giant's share of these runs, both scoring in excess of 200.

Mumbai's middle order, in contrast, has only contributed 464 of their 1119 runs, and nearly half those middle-order runs have come from Harmanpreet Kaur. The other major contributor has been Amelia Kerr, who hit an unbeaten 45 in the tournament opener. Pooja Vastrakar and Issy Wong have blown hot and cold, however, and as a result Mumbai's batting has tended to lose fizz if the top order hasn't scored too many runs, as has been the case of late. Mumbai have lost two of their last three games, managing scores of 127 and 109 for 8 in those two losses.

Warriorz and Mumbai have used four uncapped Indian players each in the competition. Warriorz, though, have also regularly played Kiran Navgire and Anjali Sarvani - who have played only six T20Is each - and Devika Vaidya, who has played 13 T20Is. Navgire began the tournament with a half-century, while Sarvani has three wickets to show in her eight appearances. Only Vaidya hasn't left a mark yet, and was left out of Warriorz's last league game. Sarvani and Parshavi Chopra have complemented the experienced Warriorz bowlers in Sophie Ecclestone, Rajeshwari Gayakwad and Deepti.

Mumbai, meanwhile, have banked a lot on their established names. Save for Saika Ishaque, who has taken 13 wickets, Mumbai's other significant contributions, with both bat and ball, have come from the likes of Harmanpreet, Hayley Matthews, Nat Sciver-Brunt and Kerr.

They will hope for more from their uncapped contingent as they look to leap past Warriorz and set up a title clash with Delhi Capitals.

Form guide

In the spotlight: Saika Ishaque and Sophie Ecclestone

In the first four games of the WPL, left-arm spinner Saika Ishaque picked up 12 wickets at an economy rate of 5.85. This was at a time when the scores were high and the overall economy rate of all bowlers were 8.44. However, Ishaque has been wicketless in three of her last four outings while going at an economy rate of 7.78. The overall economy rate of the bowlers in this period (after March 14) was 7.60. A key cog in the Mumbai bowling line-up, all eyes will be on Ishaque in the Eliminator.

Sophie Ecclestone has been a consistent performer in the WPL, picking up wickets in each of her outings. Her economy rate of 6.22 is the best among bowlers with ten or more wickets in the competition. She has also shown glimpses of her ability with the bat under pressure. Expect the England spinner to step up on the big occasion.
