The 17-year-old O'Sullivan, from Chandler, Arizona, beat France's Justine Dreher 7 and 6 in the second round, and topped Jennifer Kupcho of Westminster, Colorado, 4 and 3 in the third.

On Wednesday in the first round of match play, O'Sullivan beat Haley Mills of Tyler, Texas, 7 and 6. O'Sullivan won the Symetra Tour's Gateway Classic in February in Mesa, Arizona, at 16 to become the youngest winner in the history of the professional circuit.
