Argentina shocked New Zealand 29-23 in Buenos Aires on Saturday to record their first ever home victory over the All Blacks after 40 years of trying. Fly-half Santiago Carreras steered the Pumas to the milestone win, while coach Felipe Contepomi praised his side’s discipline and defensive aggression, noting it capped a run in which Argentina have now beaten every tier-one nation on home soil. Earlier in Cape Town, South Africa reignited their Rugby Championship title defence with a 30-22 win against Australia. Handré Pollard contributed 15 points from the tee and tries from Canan Moodie, Kwagga Smith and Eben Etzebeth gave the Springboks just enough cushion to hold off a spirited Wallabies team that had stunned them a week earlier in Johannesburg. The weekend’s results leave all four Rugby Championship sides — Argentina, New Zealand, South Africa and Australia — level on one win apiece after two rounds, throwing the shortened tournament wide open. The Pumas travel to Townsville to meet the Wallabies next, while the Springboks face the All Blacks in Wellington in a pair of fixtures that could prove decisive in the race for the southern hemisphere crown.
