Samantha Stosur’s grasscourt revival has continued with a cruisy second-round win at Wimbledon.

It wasn’t always pretty, but Stosur’s 6-3 6-4 victory over lowly-ranked Pole Urszula Radwanska followed her straight-sets first-round success on Monday.

Suddenly, after being without a win on the surface in 12 months, the Australian No.1 is into the third round at the All England Club for only the third time in 13 attempts.

The former US Open champion next faces either big-hitting American Coco Vandeweghe or 11th-seeded Czech Karolina Pliskova on Friday with hopes of making the second week of her least productive major for the first time.

Stosur made a flying start on Tuesday, breaking Radwanska – the younger sister of former finalist and world No.2 Agnieszka – twice to race to a 5-1 lead in the opening set.

She faltered trying to close it out before clinching it at the second attempt with an unreturnable wide-angled serve.

Australia’s 22nd seed fell behind 3-1 in the second set, but broke the world No.107 twice in a row to regain control before moving through to the last 32 after just 79 minutes.

Stosur’s effort matches runs to the third round in 2009 and 2013, when she lost to eventual runner-up Sabine Lisicki in three sets.
