Tenth-seeded American Madison Keys, playing just her third match of 2021, rolled to a 6-1, 6-1 win over Taiwan's En-Shuo Liang on Monday in the first round of the Dubai (United Arab Emirates) Duty Free Championships.
Keys hadn't played since the 2020 French Open before returning to reach the second round in Doha, Qatar, last week. She missed last month's Australian Open after testing positive for COVID-19.
