World number five Ons Jabeur is through to the fourth round of the US Open for the first time after coming from a set down to beat American Shelby Rogers.
Jabeur led the final set 5-1 but was broken by her American opponent as she attempted to serve out the match.
However, Rogers couldn't close the advantage any further and Jabeur broke her again to secure her place in the last 16 at Flushing Meadows.
There, the 28-year-old will play Russian Veronika Kudermetova, after the 18th seed crushed Hungary's Dalma Galfi 6-2 6-0 in 46 minutes.
