The pair traded early second-set breaks with Wozniacki breaking away for 4-2 on the way to the biggest success so far of her career.

Wozniacki will make her first career appearance in the WTA Top ten on Monday with the start of Roland Garros looming.

Mauresmo was weighed down with five double-faults while losing serve five times. The former world number one fired 23 winners and 48 unforced errors in the contest which ended just shy of the two-hour mark.

Wozniacki's best result this season was a title at a small Florida event and runner-up showing indoors in Memphis while Mauresmo claimed the Paris Indoor title in February.
