Misaki Doi - Rose Danielle Collins

Danielle Collins resumed her winning ways after a much-needed three weeks of rest. She defeated 35-year-old Kirsten Flipkens, 6-4, 6-2, in an hour and 21 minutes, dropping just one service game en route. It was her 20th win of the season on hard courts; other surfaces account for 12.
The American, who has faced multiple physical issues this season, has still succeeded in winning 18 out of her last 22 matches. She won her maiden career titles at the Palermo 250 and San Jose 500, along with a couple of decent third-round finishes in Montreal and the US Open.
Misaki Doi needed in excess of three hours to beat the struggling Marie Bouzkova, 6-3, 6-7, 6-3. She was broken four times during the marathon but returned the favor six times. It may turn out to be a crucial result, given she arrived in Chicago with losses in six of her last seven matches.
The Japanese player has cleared the second round of a tournament just once in the entire season. However, that lone instance came via the courtesy of Sara Sorribes Tormo's withdrawal at the Phillip Island Trophy. She hasn't recorded two WTA main draw wins in a row since 2019.
Head-to-head: Danielle Collins leads 1-0. The pair met for the first time in the third round of the Phillip Island Trophy in Melbourne. The former Australian Open semifinalist needed an hour and a quarter to prevail 6-4, 6-2, and went on to reach the semifinal of the 250 tournament.
