Australia's Alex de Minaur has had to dig deep to justify his No.2 seeding and move into the second round of the Vienna Open.
The 25-year-old started slowly against Germany's Jan-Lennard Struff and looked out of sorts as he dropped the first set on Tuesday. But he gradually put his game back together and won 2-6 6-2 6-2 at the indoor hardcourt ATP 500.
De Minaur converted four of his six break points in the second and third sets. He finished the second with an ace and clinched victory with an overhead smash, winning in an hour 42 minutes.
