Australia's list of injuries continued to grow with captain Aaron Finch expecting to go for a scan on Saturday after picking up a "hip or glute" problem during the first T20I.
He was clearly hampered while batting and with such a short turnaround between games - the next match is on Sunday before the final game on Tuesday - he could be in doubt.
"It's a bit of a hip or glute, we'll wait and see," Finch said in the post-match presentation. "It progressively got worse throughout the game."

Australia are already without David Warner (groin) for this series while Marcus Stoinis is still recovering from the side strain he suffered in the opening ODI. Left-arm spinner Ashton Agar was ruled out of the T20I series ahead of the first game with a calf strain and legspinner Mitchell Swepson was brought across from the Australia A squad training in Sydney to play in Canberra.
If Finch was unavailable it would be likely that Matthew Wade, who was vice-captain for the first T20I, would step up to lead. Regular vice-captain Pat Cummins has been rested for the series while previous joint vice-captain Alex Carey is currently not part of the XI. Steven Smith has not been considered for an official leadership position since his return to the game although he is now eligible to captain Australia again.
Marnus Labuschagne and Cameron Green are the other batting options in the limited-overs squad.
Following this T20I series, Finch will head onto the BBL with the Melbourne Renegades. Their opening fixture is on December 12 against the Perth Scorchers in Hobart.
