Having Sharp and J-Kerr batting down the order with Suzie Bates seems like the best combination in T20Is. While Bates' hitting ability has been overstated in recent years and she was the most expensive bowler for White Ferns vs South Africa (8.8rpo), it's clear that her team loves her and that she offers value with team culture, maturity etc.
Bates will be given ample opportunity to find her groove in this role and the best White Ferns team for the T20 World Cup will probably feature Bates, so best to get comfy with this. The change for the fifth game of this series with Flora Devonshire and Nensi Patel coming in for Bates and Rosemary Mair offered a glimpse into the depth available.
Devonshire and Patel are among the best batters for their domestic teams, so having them batting so low along with Sharp will be an asset moving forward. Some would suggest that Devonshire and Patel are better spinners than Bates, which at the very least sums up the impressive all round ability of the youngsters.
None of which takes away from the seam bowling department. Devine, J-Kerr and Lea Tahuhu took 3+ wickets with averages below 17 in the series vs South Africa. That is the best T20I seam trio available for White Ferns and then there are Rosemary Mair and Bree Illing next in line. Molly Penfold's in a funky spot competing with Kayley Knight for opportunities as an example of the seam depth.
Mair didn't take her opportunity vs South Africa and that's a theme that stretches further back. Mair joined Bates as the only White Ferns who conceded more than 8rpo vs South Africa and she took 1w @ 124avg. This year she has 2w @ 81avg/6.4rpo and last year she took 1w @ 106avg/9.2rpo.
None of which suggests that Mair should be a 1st 11 regular but she has played seven of the eight games this year and 12 of the 13 games since the start of 2025. Illing didn't take a wicket in her two games vs South Africa (6ov @ 6.1rpo) but Illing has been better than Mair since the start of 2025...
Bree Illing: 20ov, 4w @ 29.7avg/5.9rpo
Rosemary Mair: 36.3ov, 3w @ 89.3vg/7.3rpo
