Scotland’s cricketers were due to enter the second day of a four-day encounter with Australia A at Raeburn Place on the back foot after the tourists recovered from a shaky start to finish on 335-6.
At the heart of the Australian innings was a captain’s knock of 113 from Brad Haddin before he succumbed to a brilliant diving catch by Preston Mommsen off the bowling of Moneeb Iqbal.
That was the last wicket of the day to fall and Peter Siddle carried on where Hadden had left off to finish unbeaten on 85 runs.
Earlier the Scots had started brightly with Iain Wardlaw opening with a maiden over and both openers were soon back in the pavilion with the total at 23.
Three more Aussie batsmen failed to exert authority and were dismissed before Hadden and Siddle put the visitors in a commanding position entering day two.
For the Scots, who had won the toss, there were two wickets apiece for Wardlaw and Calum MacLeod.
