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.
2017–18 Ashes series The 2017–18 Ashes series is a forthcoming series of Test cricket matches to be contested between England and Australia for The Ashes. The series will be played at five venues across Australia between 23 November 2017 and 8 January 2018.
