Donaldson plays Istomin next

Uzbekistan's Istomin edged easier than expected Russian No. 3 seed Khachanov to reach the quarter-finals. The 31-year-old lost just five games on his way to clinching the win 6-3 6-2. It was the first-ever meeting between the two.

Donaldson wants to make amends

Donaldson and Istomin will be meeting for the second time ever when they meet in the Chengdu Open quarter-finals. Previously, Istomin beat Donaldson in the Madrid Masters qualifying round this past May. However, the match was played on clay — Donaldson's least favorite surface.

The Chengdu indoors tennis event is held on hard. Donaldson will surely have a better chance of beating Istomin this time. It remains to be seen can the rising American player continue his hood week and reach the Chengdu semi-finals.
