Rugby matches between South Africa and Argentina used to be predictable. You'd expect the Springboks to bully the Pumas up front, maybe a little flair from the Argentine backs, and a comfortable green-and-gold victory. But honestly? That script has been shredded.
If you watched the 2025 Rugby Championship, you know things got weird. Fast. We saw a match in London that felt like a home game for Pretoria, a record-breaking performance in Durban that left historians scrambling for their record books, and a bizarre "try from nowhere" that had everyone—including the referee—scratching their heads.
The Durban Massacre and the Rise of Sacha Feinberg-Mngomezulu
Let's talk about September 27, 2025. Hollywoodbets Kings Park in Durban. The Springboks absolutely demolished Argentina 67-30. But the scoreline doesn't even tell the half of it.
The first half was a dogfight. At 25-23 going into the break, it felt like anyone’s game. Argentina was tenacious, basically living off South African errors. Then, the second half happened. South Africa unloaded 42 points while the Pumas basically stood frozen.
Sacha Feinberg-Mngomezulu—the name is a mouthful, but the game was even bigger. He dropped 37 points. That isn't a typo. He broke Percy Montgomery's long-standing record for the most points by a Springbok in a single Test match. He scored a hat-trick of tries, converted eight others, and slotted two penalties. It was the kind of individual performance that makes you realize you're watching a generational talent take the keys to the No. 10 jersey.
But it wasn't just about the points. It was the way he did it. Flick passes, line breaks, and a level of composure that's frankly scary for a kid with only 13 caps at the time.
That Bizarre Try Nobody Saw Coming
You've probably seen the clip by now. If not, it’s worth a re-watch just for the "what on earth?" factor.

In that same Durban match, Cheslin Kolbe—usually the one doing the magic—accidentally gifted Argentina one of the strangest tries in Test history. Kolbe went to ground the ball behind his own try line for a routine goal-line drop-out. He casually drop-kicked the ball toward Feinberg-Mngomezulu, thinking the play was dead and they were just resetting for the kick.
The ball was live.
Santiago Chocobares, being the opportunistic shark he is, just walked up, snatched the ball, and dived over. The Boks stood there looking at the ref, the ref looked at the TMO, and eventually, the try stood. It was a lapse in concentration that Rassie Erasmus likely didn't let them forget for a month.
Why Twickenham Became "Bokkenham"
One of the biggest talking points of 2025 was the decision to play a "home" game for Argentina at Allianz Stadium (Twickenham) in London. It happened on October 4.
Why London? Money, mostly. But it backfired for the Pumas.
Out of a crowd of 70,000, it felt like 65,000 were wearing green. It was a sea of South African jerseys. Even though the Pumas fought like cornered animals, losing 29-27 in a heart-stopper, they had surrendered their biggest weapon: the hostile atmosphere of an Argentine crowd.

Rassie Erasmus was pretty blunt about it afterward. He admitted they were "fortunate" not to be playing in Argentina. He’s right. The Pumas are a different beast in Santiago del Estero or Mendoza. Taking that game to London essentially handed the Springboks back-to-back Rugby Championship titles on a silver platter.
Key Stats from the 2025 Clashes
- South Africa vs Argentina (Durban): 67-30 (Boks win)
- Argentina vs South Africa (London): 27-29 (Boks win)
- Scrum Dominance: In the London match, the Boks won despite a "patchy" performance, purely because their scrum was an unstoppable force.
- Discipline: Argentina conceded an average of 11 penalties per game across the tournament, a habit that ultimately cost them the trophy.
The Strategy: Power vs. Chaos
Argentina’s coach, Felipe Contepomi, has tried to evolve the Pumas into a high-octane, chaotic team. They want to move the ball. They want to tire out the big men. And for 40 minutes in most games, it works.
But the Springboks under Rassie and Tony Brown (their attack coach) have added a layer of sophistication that’s hard to beat. They still have the "Bomb Squad"—that terrifying bench of six forwards—but now they have a backline that can score from anywhere.
Take the scrum-half battle. Cobus Reinach is still lightning fast. He scored twice in London, proving that even at his age, his support lines are elite. When you pair that with the raw power of Malcolm Marx (who also bagged a double in London), the Pumas just couldn't sustain the pressure for a full 80 minutes.
What Most People Get Wrong
People think South Africa vs Argentina is just a warm-up for the Boks before they face New Zealand. That’s a mistake.
In 2024, Argentina beat the Boks 29-28 in Santiago del Estero. They are the only team in the world that consistently finds ways to make the Springboks look "sloppy," as they did in the first half of the London test. They force South Africa into individualistic play, breaking down the disciplined structures the Boks usually rely on.

If Argentina can ever fix their scrum—which was pushed back even when South Africa was down to seven men in a pack—they’d be world-beaters. Right now, the set-piece is their Achilles' heel.
Looking Ahead to 2026
The rivalry is only getting more intense. We're seeing a shift where the "Big Three" of the Southern Hemisphere is very much a "Big Four."
Argentina proved they can beat anyone on their day, having knocked over the All Blacks in Wellington and the Wallabies in 2025. But to beat South Africa consistently, they need more than just "passion" and "chaos." They need a front row that can survive a 60-minute onslaught.
If you’re following this rivalry, keep an eye on the young guns. Sacha Feinberg-Mngomezulu is the obvious one, but watch out for Argentina’s Joaquin Oviedo. The guy is a "human bulldozer" and is becoming the heart of that Pumas pack.
Actionable Insights for Fans and Analysts
- Watch the Scrum: If Argentina is conceding more than two scrum penalties in the first 20 minutes, the game is likely over. They can't recover from that kind of set-piece drain.
- The 50-60 Minute Mark: This is when the Springboks deploy the bench. If the Pumas aren't leading by at least 10 points at this stage, the "Bomb Squad" will almost certainly overwhelm them.
- Discipline is Everything: South Africa's kickers (especially Sacha) are currently operating at over 85% success. Giving away "cheap" penalties inside the 40-meter line is essentially gifting the Boks points.
- Follow the Venue: Always check where the game is being played. A neutral venue like London favors the Boks’ global fan base. A game in Argentina is a 5-point advantage for the Pumas before the whistle even blows.
The days of South Africa walking over Argentina are gone. Every match now is a tactical chess game played at 100 miles per hour, and as 2025 proved, you can't afford to blink for even a second.
