Naomi Osaka, the 2019 Beijing champion and 12th seed, meets Maria Timofeeva in a first career meeting.
Osaka is ranked 17th and has a 13-6 record on hard courts this year. Her serve and first-strike forehand are still the best weapons in this match, and she tends to play her cleanest tennis on this surface. Her weakness is consistency over a full match, especially when rallies get long and her opponent keeps the ball in play.
Timofeeva has had a strong season with four titles and a 38-17 record, though most of that success came on lower-level events. She beat Darja Vidmanova 6-3, 6-3 in round one and will compete hard. Ranked 68th, she moves well and defends solidly, which tests Osaka's patience.
The key is Osaka's error count. If she keeps unforced errors in check, her power should carry her. If the match turns into a long rally contest, Timofeeva has the legs and form to make it a third set.
Prediction: Osaka to win in three sets. Confidence: medium-high.
