Death by match-ups

With one bad evening, South Africa's World Cup campaign crumbled. It's a horror movie they have starred in many times before—a stumble when the stakes are highest. But to label this defeat another 'choke' would be unfair to New Zealand, stripping credit from a calm, methodical takedown of an opponent they had lost to recently. Mitchell Santner and his men deserve their flowers.

New Zealand arrived as humble underdogs, a tag that follows them. This time, it was because South Africa were on a roll and had humbled them in the group stage in Ahmedabad. Santner openly addressed the biggest pain point from that match: their Powerplay bowling. That day, six overs of pace to Aiden Markram, Quinton de Kock, and Ryan Rickelton yielded 83/1.

Santner showed how leaning on even basic tournament data could rattle South Africa early. When Quinton de Kock took strike in the second over, he faced off-spinner Cole McConchie. Off-spinners have found success in this T20 World Cup, and South Africa have used them too. McConchie preyed on De Kock's weakness, dismissing him in three deliveries with a shorter ball hit to mid-on. For the fourth time in 44 tournament deliveries, the South African opener fell to an off-spinner.

Ryan Rickelton arrived next and got a similar delivery, cutting it straight to backward point. South Africa were 12 for 2, their early flourish cut down. They limped to 48/2 in the Powerplay, playing an unprecedented 20 dot balls.

South Africa's batting depth has seen them consolidate in middle-overs better than any team, scoring at 9.65 an over. Early wickets made that harder, but Santner pushed them further back. Against Markram and Dewald Brevis—two right-handers—he used left-arm spin from both ends.

Rachin Ravindra hasn't made the runs New Zealand wanted from their No.3, but he coolly bagged nine wickets in the last three games. When Ravindra bowled, Markram was meandering at a run-a-ball. He took on the spinner and found Daryl Mitchell at long-on. Markram has struggled against spinners, and Santner cashed in.

In his next over, Ravindra toyed with variations. Brevis hit a one-handed six off a tossed-up ball, but Ravindra went shorter and quicker to contain him. When the strike turned over, he gave Miller flight outside off, and the left-hander hit straight to Mitchell at long-off.

An over later, Tristan Stubbs fell to a tame full ball from James Neesham, hitting to cover. South Africa were 77/5 in the 11th over, their momentum gone. Marco Jansen did patchwork at the death, but New Zealand conceded just 63 in the middle phase at seven an over.

New Zealand's simple route through match-ups might seem old-fashioned. McConchie bowled one over for his two wickets—he wasn't needed again. Santner and Ravindra combined for eight overs of left-arm spin, giving only 54 runs. Finn Allen then stomped on the wounded opposition with a mind-boggling century, but New Zealand's victory was built on the precursor to that effort.

Not long ago, New Zealand players were cooped up in their Colombo hotel, nervously watching Pakistan and Sri Lanka decide their fate. Now, Santner and his men know what four days and watertight planning can do.

By Thursday evening, they'll be in Ahmedabad, watching India take on England in the second semifinal. This time, it won't matter which way the wind blows.
