The left-arm web: how spin is hindering South Africa's World Cup

Around the time Pakistan's Nashra Sandhu was running through the Australia middle order in Colombo with her left-arm spin on Wednesday, India captain Harmanpreet Kaur was taking left-arm spin throwdowns in Visakhapatnam to prep for their next clash. That match is against South Africa, who had dramatically crumbled to the left-arm spin of Linsey Smith in their opening game.

The theme of left-arm spin kicked off this World Cup especially after South Africa had rolled over for 69 in Guwahati, that too against the new ball, when Smith struck in each of her first three overs with deceptive use of her drift and natural variations. If Laura Wolvaardt and Tazmin Brits hardly moved their feet, Marizanne Kapp tried to reach the pitch of the ball and still saw the ball go through the gate, making the top order look clueless against left-arm spin.

But do South Africa really have a problem against left-arm spin?

Wolvaardt had been prepping with batting coach Baakier Abrahams on match eve for England's left-arm spinning duo of Smith and Sophie Ecclestone, and the use of Smith with the new ball turned out to be key for England. It was, however, no surprise that Wolvaardt dismissed any similarities between that and how South Africa lost six wickets to Sandhu - four by the 17th over - in the third ODI against Pakistan just before the World Cup, because in the series before that, South Africa didn't look troubled while facing left-arm spin against West Indies and in the tri-series involving India and Sri Lanka earlier this year. In fact, since the start of 2024, the South Africa batters average a solid 42.50 against left-arm spin, which ranks third among Full Member teams, after England and Australia.

But it's for a reason that England handed the new ball to Smith as soon as they opted to field. South Africa's scoring troubles against left-arm spin appear more prominent when the ball is new: since the start of 2024 and until that match against England, South Africa had been scoring at just 4.03 an over in the powerplay against left-arm spin - much slower than England, West Indies, Sri Lanka and India - even if they weren't losing as many wickets (just three in 192 balls).

England were also not the first ones to use the left-arm spin threat against South Africa, who have faced the most such deliveries since the start of 2024 (192 in 11 innings), while India have had to face just 120 such balls in 10 innings. Even if England employed Smith early on to put the brakes on South Africa, the Guwahati pitch that had turn and grip on offer worked wonders for her, while the South Africa batters played the wrong lines.

It obviously doesn't help South Africa that their entire line-up is stacked with only right-hand batters, which gives the opposition the luxury of attacking or strangling them with left-arm spinners. It's a tactic New Zealand, South Africa's next opponents, could not employ as their only left-arm spinner - the uncapped Flora Devonshire - was ruled out of the World Cup just before their clash, and South Africa had no issues in tackling the New Zealand's offspinner or legspinner on a much flatter track in Indore.

But why are left-arm spinners tougher to face for right-hand batters than offspinners or legspinners?

"…Especially with the conditions that we've got in Guwahati and in Sri Lanka with the ball gripping and turning a bit, it's always an advantage for a [left-arm] fingerspinner," India's Jemimah Rodrigues said on Wednesday. "And if someone has that good quality who can mix it up with bowling in (angling it in) and bowling out (turning it away), I think that's where the challenge comes. I think it's always great to have a good left-arm spinner on your team."

Come Thursday, South Africa will be up against a team who have two left-arm spinners in the squad, even though only Shree Charani has played the two India games so far while Radha Yadav has sat out. Whatever the conditions in Visakhapatnam, if India pick the more experienced Radha as well, it will surely plant a seed of doubt in South Africa's mind of how to go about their approach against them.

It's not all doom and gloom for them though. Even if South Africa have the third-worst powerplay scoring rate (2.60) and the most wickets lost (three) against left-arm spinners in the early stages of this World Cup, they can take confidence from the fact that their captain Wolvaardt, who opens the innings, doesn't fall too often to left-arm spinners and has largely picked up her scoring rate against them since her debut in 2016, averaging 67 and 51 while facing them in 2024 and 2025 respectively. South Africa will hope she leads them from the front on Thursday and then against Bangladesh, Sri Lanka and Pakistan as well, who can all slot a few left-arm spinners in their XIs.
