Having lost only once since winning the 2011 World Cup, New Zealand’s All Blacks continued their reign as world No. 1 with a 37-28 triumph over South Africa in the Rugby Championship in Johannesburg. After slipping to No. 2 after 101 weeks atop the tennis pantheon, Novak Djokovic defeated No. 1 Rafael Nadal to claim the China Open title in Beijing. In the NFL, the New Orleans Saints and Kansas City Chiefs remained unbeaten at 5-0, as did the Denver Broncos thanks to the continued resurgence of the “Prometheus of Dad-Rock,” 37-year-old quarterback Peyton Manning, who put 414 passing yards and 51 points on the board against Dallas. And the sporting world’s eyes turn to an unusual spot today: Buckingham Palace, where Prince William will host a match on the palace grounds to celebrate the English Football Association’s 150th anniversary.
