Naomi Osaka has edged ever closer to a blockbuster Australian Open fourth-round clash with Ash Barty after overcoming a second-set wobble against Madison Brengle to power into the third round.
Defending champion Osaka breezed through her opening set against the American in just 20 minutes but had to push through her own errors and recover from a break down in the second to prevail 6-0 6-4.
