A bid to make the last eight
It is that kind of attitude that has helped Thiem retain his place inside the top 10 this year and the 24-year-old is leaving no stone unturned in his bid to make the last eight for the first time, including standing closer to the baseline on returns.
“I have to, on hard courts,” he said. “I have to move closer to the lines. First serve I think, especially against a really good server like Taylor, it's impossible to return far back. Second serve, I try to mix it up a little bit. But in general, of course, I'm practising to come close to the baseline, especially on this surface.
“I didn't have any good experiences yet in the fourth round, so I don't rely on them,” he said. “It's always something special for me to reach the second (week) of a slam. Let's see who I play. But one thing is for sure. I will give everything to maybe make the first quarters here.”
Thiem will now play Kevin Anderson, the South African who reached the final here last year and the final at Wimbledon last month, after he edged out Denis Shapovalov in five sets.
