Steve O’Keefe and Jon Holland were in the mix for the SCG Test but Australia selectors opted for left-armer Ashton Agar.

Ashton Agar could join Nathan Lyon in a two-man spin attack after he was added to an extended Australia squad for the fifth and final Ashes Test against England in Sydney.

Steve O’Keefe and Jon Holland were in the mix for the SCG Test but selectors opted for left-armer Agar, it was announced on Saturday.

Agar, who was involved in the Bangladesh tour, has made four Test appearances but never on Australian soil.

The 24-year-old – famous for scoring 98 runs on his Test debut against England in 2013 – missed the early part of the Sheffield Shield season due to a broken finger in October – making only one appearance with Western Australia for four wickets.

Agar, who boasts the third-best bowling economy in the Big Bash League this season, helped Perth Scorchers beat Melbourne Renegades by three wickets on Friday.

Australia have already reclaimed the Ashes after taking an unassailable 3-0 series lead prior to the Boxing Day Test in Melbourne.
