BRISBANE, Australia — Madison Keys beat Samantha Stosur 7-5, 6-3 on Wednesday to be among three Americans with second-round wins at the Brisbane International.
Stosur had beaten former world No.1 Angelique Kerber to progress beyond the first round at the tournament for just the second time in seven years on Monday.
The Australian had an early break against Keys, the 2017 U.S. Open finalist, but the American broke back in the next game and then in the 12th game to take the first set.
Keys broke serve again to begin the second set before sealing victory in 77 minutes.
“Sam obviously has a great serve and a great forehand and she’s really tricky off of her slice,” Keys said. “So I’ve known that in the past; I just felt like in the past I wasn’t doing a great job at handling my side of the court.”
Stosur will continue her Australian Open preparation at the Hobart International next week.
In earlier American victories, Alison Riske beat Barbora Strycova 6-3, 6-4 and Danielle Collins defeated Yulia Putintseva 6-1, 6-0.
Australian world No. 1 Ashleigh Barty won’t begin her singles campaign until Thursday but is already just one win from the doubles final.
Barty combined with Dutch player Kiki Bertens to beat second-seeded Nicole Melichar and Yifan Xu 6-3, 6-2 in less than an hour on Wednesday.
Barty will play American Jennifer Brady in the second round in singles on Thursday.
DALLAS – Marcos Giron advanced to the second round of the Dallas Open with a 6-4, 6-7 (1), 6-1 victory over Alex Rybakov on Tuesday.
The seventh-seeded Giron, who reached the semifinals of the inaugural event a year ago, responded quickly after failing to close out the second set, winning the first five games of the deciding set.
Rybakov broke his fellow American when Giron was serving for the match in the second set. Then Rybakov won the first six points of the second-set tiebreaker.
“I’m really happy with how I was able to reset in the third and just get back to the game plan from the beginning and elevate,” Giron said. “He played well and served well and kind of hung in there.”
Eighth-seeded Adrian Mannarino of France won the final five points of a first-set tiebreaker and the last four games of the second to beat American Steve Johnson 7-6 (6), 6-2.
J.J. Wolf, the No. 6 seed, had little trouble in a 6-3, 6-3 victory over fellow American Brandon Holt.
John Isner, the fifth seed and unofficial tournament host in his hometown event, played later Tuesday. Like Giron, Isner lost in the semifinals last year.
DALLAS – Wild-card entry Jack Sock opened with a 7-6 (2), 4-6, 6-4 victory over Ilya Ivashka at the Dallas Open, setting up a second-round meeting with top-seeded fellow American Taylor Fritz.
Sock broke Ivashka’s serve in the final game to win the match. Ivashka fell behind 2-0 to start the final set but broke Sock to get back on serve.
Down a break early in the second set, Ivashka rallied to force the deciding set after Sock cruised in the first-set tiebreaker.
The eighth-ranked Fritz is back for the second Dallas Open after losing in the semifinals as the top seed in the inaugural edition of the indoor hard-court event last year. Defending champion Reilly Opelka isn’t in the field.
