All eyes will be on India's captain Harmanpreet Kaur when she plays her 200th T20I against South Africa in Manchester but her opposite number, Laura Wolvaardt, could attract as much attention, albeit for different reasons.
After finishing as the leading run-scorer in each of the last three ICC events, Wolvaardt finds herself far off the pace at the start of this one. Not only has she struggled to repeat her feats of tournaments of old, she has been starved of the strike at the start of the innings as teams have targeted tying her down. India will have been taking notes.
Though this is their first meeting against South Africa at a T20 World Cup, they played each other in a five-match series as recently as two months ago. India lost 4-1 and were beaten largely by Wolvaardt's runs. She was the series' leading batter, with 330 runs from five innings, including a century and three fifties and gave South Africa starts from which India could not pull them back. Across the five innings of that contest, Wolvaardt faced 98 balls in the Powerplay and scored 176 runs: more than half her total tally, at a strike rate of 179.5. At this tournament, Wolvaardt has only been on strike for 21 balls in the Powerplay and managed just 21 runs. Is that a growing concern?
"You always want to be facing many balls, especially a player like Laura," Chloe Tryon, South Africa's vice-captain said, at the pre-match press conference. "For us it's just being proactive as a batting unit. We probably haven't rotated as well as we should have."
Some of the onus of that falls to Wolvaardt's opening partner, Sune Luus. While she was in relatively good form in the pre-tournament series against India, and scored two half-centuries, Luus has a better record in the middle-order. So far she has scores of 1 and 5 at this World Cup and there may even be an argument to bring Tazmin Brits in her place. Whatever happens, Tryon hopes they can build a solid stand to help Wolvaardt get out of this mini-rut.
"You win cricket games if you have really good partnerships with the bat. And we've obviously not had enough of that, especially building an innings. That can put frustration on the player," Tryon said "But we know our capabilities. We've had a lot of chats about how we can approach different games and how we can keep encouraging others to just keep getting better. And being able to communicate things in the middle."
One of things South Africa must have spoken about when strategising is that India could be the perfect team for Wolvaardt to face right now. At this World Cup, India have taken only two wickets in the Powerplay, the same as Netherlands and Scotland. Only Sri Lanka, with one wicket, have done worse.
A fresh Old Trafford pitch should offer more zip than it did at the venues for the opening fixtures last weekend so batters can expect the ball to come on quicker, Equally, temperatures are much warmer and humidity higher than it was seven days ago, when South Africa played Australia in Manchester, which suggests there could be some movement on offer as well. That could prompt India to pick Renuka Singh, who has yet to play at this tournament, while South Africa will look to Marizanne Kapp and Shabnim Ismail.
And so to the other half of what Wolvaardt has to manage. Her seamers have been good without grabbing headlines and the jury's still out on the efficacy of Ismail's retirement u-turn. That she is quick and scary is not in doubt. Whether that means she will win South Africa matches remains to be seen. The talk around her remains positive though.
"I feel like she's never left. She's fitted in perfectly," Tryon said. "She's enjoying being in the group, she's gelled really well with the bowlers and they have a lot of communication around how they can improve in different areas and different phases of the game. She's brought a lot of knowledge. She's got a lot of experience. She's played in various World Cups. So having the girls listen to her and her information is really important."
Information is always good but what counts is how a team uses it. South Africa, with a host of support staff including Surrey women's coach Johann Mybrugh, have done as much homework as they could. It didn't really show in their opener against Australia or in how close they came to making a mess of a modest chase against Pakistan but they're still in it. The India match is as close to a quarter-final as it comes. Win it, and they leave India facing the challenge of having to beat Australia in the final group match. Lose it, and they're all but out, The enormity of South Africa's task and their captain's role in it has not escaped them as they gear up to face their biggest challenge of the tournament so far.
"It's going to be really difficult and probably going to be really loud here tomorrow. But our destiny is in our hands," Tryon said. "We know how important this game is for us. And we can't overthink it too much. And we can take what we learnt in that 4-1 series win but not dwell too much on that. We can take the positive from it but it's different going to a World Cup. There's a lot of pressure added. And we know it's like a quarter-final. Our destiny is in our hands so how can we make sure we're playing our best cricket?"
