Two-time Grand Slam champion Naomi Osaka managed to overcome her own uneven play to pull out a three-set victory over Misaki Doi in an all-Japanese matchup in the first round of the U.S. Open.
The No. 4-seeded Osaka's movement was an issue at times but she managed to win 6-2, 5-7, 6-2 against the 81st-ranked Doi in an empty Arthur Ashe Stadium as midnight approached.
Osaka made 38 unforced errors, 13 more than her winner total.
Osaka is coming off a left hamstring injury that forced her to withdraw from the final of the Western & Southern Open on Saturday.
