Samantha Stosur is through to the third round of the Cincinnati Masters thanks to a straight-sets win over American wildcard Jamie Hampton.
The 11th-seeded Australian triumphed 6-3 7-6 (7-3) on Wednesday, needing one hour and 42 minutes to account for the world No.26.
Stosur will next face either eight-seeded Frenchwoman Marion Bartoli or Romanian Simona Halep.
With the US Open starting in 11 days, Stosur will be hoping to continue her hardcourt build-up to the grand slam tournament she won in 2011.
The 29-year-old lifted the Southern California Open title two weeks ago in Carlsbad.
