Samantha Stosur has launched her 14th Wimbledon campaign with a straight-sets victory over little-known Pole Magda Linette.

Australia's top-ranked player safely progressed to the second round with a relatively comfortable 7-5, 6-3 win at the All England Club.

Stosur's reward is a showdown on Wednesday with former finalist Sabine Lisicki, who looked ominous in dispatching rising American Shelby Rogers 6-1, 6-3 in less than an hour.

Seeded 14th after her run to this month's French Open semi-finals, Stosur offset four aces with six double-faults but dropped serve just once in the 77-minute workout.

The former US Open champion was playing her first grand slam match under new coach Andrew Roberts, the Tasmanian helping Stosur during the grasscourt season following her split from long-time mentor David Taylor.

Roberts would have been impressed with Stosur's confident start as she held her opening two service games to love before breaking Linette to charge ahead 3-1.

But as the errors began to creep in, Stosur dropped serve and appeared to be heading to a tiebreaker until breaking the world number 92 for a second time to nab the opening set after 44 minutes.

Stosur cruised through the second set without facing a break point and clinched victory with an ace.

Sam Groth, the day's only other Aussie in action, continued his grand slam woes with a straight-sets first-round loss to Japanese fifth seed Kei Nishikori.

Groth succumbed 6-4, 6-3, 7-5 in another rankings setback after reaching the third round at the All England Club last year.

The Newcombe Medallist for his outstanding performances in 2015 now faces a fight to secure direct entry to the US Open, the last major of the year starting on August 29.

Big guns Nick Kyrgios and Bernard Tomic, seeded 15th and 19th respectively in the men's event, plus John Millman, Jordan Thompson, qualifiers Luke Saville and Matt Barton and Daria Gavrilova all play on Tuesday.
