Alexander Zverev vs. Dominic Thiem
In the first set of Alexander Zverev’s quarterfinal match against Stan Wawrinka, Zverev looked lost. Wawrinka’s powerful serve and backhand were moving Zverev around the court, preventing him from gaining purchase in any of the points. He lost the first set in just 26 minutes.
Zverev, the seventh seed, used his serve to settle back into the match.
