Naomi Osaka will face Amanda Anisimova in round three of the Australian Open after easing past Madison Brengle on Wednesday.
The two-time champion in Melbourne won 6-0 6-4 to set up a meeting with the 20-year-old American, who earlier upset Olympic gold medallist Belinda Bencic in straight sets.
Despite a second-set wobble on serve that gave Brengle hope of a comeback, Osaka looked in comfortable control of the contest and has now dropped just one set in her five matches in 2022.
Brengle was a 6-2 6-2 winner in the only previous meeting in Rock Hill way back in 2013, when Osaka had just turned 16 and had barely any Tour experience. Against the Osaka of 2022, a four-time major champion, she had few answers.
Osaka tore through Brengle's defence in the opening set, wrapping it up in 20 minutes while dropping just three points on serve.
Brengle was credited with just one winner in her chaotic first-round match with Dayana Yastremska, who retired trailing 6-1 0-6 0-5. It was not until the second game of the second set that Brengle matched that tally, but it was worth the wait: a brutal inside-out backhand across court, celebrated with gusto, as she began to make inroads on the Osaka serve.
Osaka dug deep, saving three break points before holding for 2-1 and then another with a timely ace in her next service game. Her play was becoming erratic, though, and after saving a further three break points at 3-3, a wild overhead handed Brengle the breakthrough.
Yet if the 31-year-old thought then that the match was just getting started, it was suddenly over. Osaka broke back immediately with a backhand volley at the net and did not lose another point from there, clinching the contest when Brengle's passing shot dropped wide.
DATA SLAM: Osaka into overdrive
Brengle quadrupled her winner count from her first-round match, but the world number 54 was simply outgunned by Osaka when it came to rallies.
The Japanese star fired in 37 winners to 32 unforced errors, turning on the power just when it seemed like the contest was balancing out.
