South Africa secured their first Rugby Championship title in five years with a dominant 48-7 victory over Argentina in Nelspruit. 

The Springboks dominated from the off, with first-half tries from Aphelele Fassi (two), Pieter-Steph du Toit and Cheslin Kolbe handing Rassie Erasmus' side a comfortable advantage. 

But an ill-disciplined Pumas display proved to be their downfall, with replacement Pablo Matera seeing his yellow card upgraded to a red on 20 minutes for making needless head contact during his challenge on Vincent Koch. 

The fixture was then firmly ended as a contest after a competitive first period when full-back Santiago Carreras joined Matera in the sin bin for a deliberate knock-on, reducing the visitors to 13 players while allowing the Springboks to hammer home their advantage. 

Malcolm Marx was the first to capitalise, with Du Toit quickly notching his second try of the encounter, before Jesse Kriel sealed a memorable triumph after latching onto the end of Handre Pollard's kick.

Tomas Albornoz scored the Pumas' only try in the contest, with the Springboks avenging last weekend's one-point defeat in Argentina, which briefly delayed their coronation. 

Data Debrief: Etzebeth makes history as Springboks seal title

South Africa sealed just a second Rugby Championship triumph in the competition's full format since 2009, while adding to last year's World Cup success. 

There was also an historic 128th Springbok appearance for lock Eben Etzebeth, who surpassed Victor Matfield as his county’s most-capped player.

Malcolm Marx scored two tries in the second half to lead South Africa to a 30-12 victory over Australia in rainy Perth.

After a tight first half, the Springboks asserted their dominance to make it two wins from two in the Rugby Championship ahead of their meeting with New Zealand next week.

Noah Lolesio's penalty gave Australia the early lead, but they could not hold onto it for long as Sacha Feinberg-Mngomezulu equalised moments before Aphelele Fassi latched onto a long kick to touch down the first try.

Lolesio slotted in two more kicks only to miss another on the stroke of half-time that would have given the Wallabies the lead.

They were punished for it after the break as Marco van Staden and Malcolm Marx twice touched down to maintain South Africa's perfect start.

Though it was a marked improvement for the Wallabies from their opening-day performance in Brisbane, Joe Schmidt still has work to do to get them ready for Argentina next weekend. 

Data Debrief: Springboks extend Australian run

South Africa have now won each of their last three Test matches against the Wallabies in Australia. The last time they recorded a longer such winning run was a four-match span from July 1971 to July 1993.

Though Australia have suffered back-to-back defeats, they showed more of a fight. Last week, it took them 75 minutes to score, compared to just three this time around.
