South Africa beat Argentina 17-10 in Buenos Aires on Saturday and left the Estadio Jose Amalfitani with the win, the momentum and a captain they may not have for Ellis Park.
Siya Kolisi lasted 25 minutes on his first start of 2026 before Andre Esterhuizen fell across him at a ruck. He walked off clutching his hamstring, replaced by Marco van Staden, with the opening Test of the four-match Rugby's Greatest Rivalry series against the All Blacks two weeks away.
The rugby around it was a struggle for the world champions. Santiago Carreras opened the scoring with a third-minute penalty, Sacha Feinberg-Mngomezulu levelled, and Benjamin Grondona powered over on 10 minutes after Lood de Jager's knock-on. Edwill van der Merwe finished a slick backline move under the posts to make it 10-10 at half-time. Cameron Hanekom's 63rd-minute try from the base of a dominant scrum, converted by Handre Pollard, was the only score of the second half.
Argentina had the last play of the game, 14 phases of it, and Matias Moroni knocked on with the line in front of him.
News24's Lloyd Burnard called it "easily the biggest test they have had this year" for the Springboks and wrote that "it was an absolute war" from the first whistle to the last, with Argentina answering everything South Africa threw at them.
Clinton van der Berg, writing for SA Rugby magazine, framed the result as a warning rather than a win. South Africa lost the collision battle for long stretches, he argued, a rare thing for a side built on physical dominance, and Argentina's line speed crowded Feinberg-Mngomezulu out of the game on his return from injury. His conclusion was that Dave Rennie's notebook is now bulging: if the All Blacks can limit South Africa's set-piece, there is a template here for attacking the Boks in unorthodox ways.
Planet Rugby's Jared Wright rated the replacements as the difference, noting the Bomb Squad "wasn't an explosion but it was enough to get the job done", with Van Staden brilliant from the moment he came on for Kolisi and Ben-Jason Dixon and Cobus Wiese adding the physicality that had been missing.
Hanekom, on his first start at No 8, was the one Springbok who matched Argentina collision for collision. That may prove convenient. Speaking on the Boks Unpacked podcast before the Test, Springboks legend Schalk Burger had already flagged him as a solution rather than a stopgap.
"If you look at the Springboks, we've got a couple of older hands coming back; we haven't seen Lood de Jager, Eben Etzebeth," Burger said. "What we've created by default is another two layers of players who can fill in and have already played this season. You think Ben-Jason Dixon, Cobus Wiese and Cameron Hanekom. Cameron Hanekom potentially becomes the new Kwagga Smith on the bench."
Burger believes that depth is where a four-Test series is won.
"The big issue for the All Blacks is the way they play. There's going to be nothing in these four Test matches, but it's four games back-to-back, so it's depth," he said.
The counter-argument arrived on the same weekend. Argentina, a side South Africa were expected to manage comfortably, took the world champions to the final phase of the match with a game plan built on tempo, offloads and niggle at the breakdown.
South Africa now head home for the series that defines their season. Etzebeth got through a solid 50-plus minutes, Boan Venter and Grobbelaar put in claims for the Ellis Park 23, and Feinberg-Mngomezulu built into the game after a scratchy first half. The one number that matters this week is on Kolisi's hamstring scan.
