Well.. it is a three match series, and then Scots still have two matches remaining. And given their track record, I won't be extremely surprised if they win at least one of these matches.
It isn't going to happen for sure. And I will consider it as extremely surprising if Scotland somehow managed to win any match against Australia. Either Jake Fraser-McGurk or Travis Head is enough to destroy the opponent team bowling attack. Both of them were magnificent in the last IPL season. Australia is playing with their full strong squad. Now it is impossible for Scotland to win against this squad of Australia.
