Alexander Zverev upset third seed Daniil Medvedev 6-4 5-7 6-4 on Thursday in a windy clash between former champions to secure his spot in the Cincinnati Open quarter-finals.
Zverev, who came into the match with a 6-9 record versus Medvedev and having lost all three of their meetings this year, broke the Russian three times and saved six of eight break points to seal victory in two hours 32 minutes.
"Very difficult conditions but also a very difficult opponent," German 16th seed Zverev said in his on-court interview. "He is somebody that gives you absolutely nothing. You have to win the match yourself and that's what I did today and I am pleased with that."
