What sport is involved in both the 2013-14 Sheffield Shield season and 2013-14 Ashes series?
2013–14 Sheffield Shield season The 2013–14 Sheffield Shield season was the 112th season of the Sheffield Shield, the domestic first-class cricket competition of Australia. It was held after the conclusion of the Ryobi One-Day Cup and included a break halfway through for the entirety of the Big Bash League. As a part of Cricket Australia's campaign for day/night Tests, it included three day/night matches, played with the pink ball. The separation of the tournaments meant that players in the national Test squad only played two or three Shield matches before the first Test of the 2013–14 Ashes series.
The Rugby Championship The Rugby Championship is an international rugby union competition contested annually by Argentina, Australia, New Zealand, and South Africa. Prior to the 2012 tournament, when Argentina joined, it was known as the Tri Nations. The competition is administered by SANZAAR, a consortium consisting of four national governing bodies: the Argentine Rugby Union, Australian Rugby Union, the New Zealand Rugby Union and the South African Rugby Union.
