Spinner Stephen O'Keefe says he can play a match-winning role in the third Test, as coach Darren Lehmann revealed Australia are seriously considering playing spin twins on home soil for the first time in nearly 10 years.
O'Keefe was named on Wednesday in a 13-man squad for the inaugural day/night Test but his chances of adding to his only cap hinge on the Adelaide Oval being baked into a dusty turner by the oppressive heat. 
History, however, is stacked against O'Keefe. Australia have not played more than one spinner in a Test at home since 2006 when Stuart MacGill and Shane Warne bowled in tandem at the SCG against South Africa.
But Lehmann, the national coach and a selector, has floated the prospect of O'Keefe joining Nathan Lyon in the XI next week. "We'll wait until we see the wicket, but that's why we've included Stephen in the 13. We're seriously looking at it [two spinners]," Lehmann said.
"His record in shield cricket, he continues to rack up the numbers. A good competitor. He was our second spinner for Bangladesh, which didn't go ahead."
O'Keefe's promotion is more disappointment for Ashton Agar, Glenn Maxwell and Fawad Ahmed, who all had reason to believe they were in the frame for the series finale. O'Keefe, who has 181 first-class wickets at 25, has been rewarded for a strong tour of India with Australia A during the winter. He has an excellent record in Adelaide, with 31 wickets at 19.48, and has become a pink-ball specialist, snaring 18 victims at 18 in three matches under lights - all at next week's Test venue.
"I've certainly had success with the pink ball. I think the selectors have noticed that, hence why I'm getting the opportunity," O'Keefe said.
"I've played three pink-ball games now, they've all been at Adelaide Oval and in each case I feel like the pink ball has helped our spinners and I've had success with it.
"Fingers crossed Steve Smith and the selectors see it the same way as I do and if there's that option for a second spinner let's run with it and hopefully I can repay that faith."
Insiders have noted the improvement in O'Keefe's game since his only appearance in the baggy green, against Pakistan in Dubai last year.
"I've played over 50 first-class games now, the one Test, I've worked hard at state level, I feel as prepared as I can be without playing Test cricket or playing for Australia," O'Keefe said.
"I've played a handful of Aussie A games in which I think I've done well. My numbers would suggest that.
"Test level is that next level up ... it'll be tough work but I feel confident in my own ability that I can get in there and do a job and a match-winning job if that's required."
O'Keefe also has extended experience bowling with Lyon. Although they flopped in Dubai 12 months ago, they bowled NSW to the Shield title two seasons ago.
"On wickets that are conducive to spin we pose a considerable threat," O'Keefe said.
