Seventeen-year-old American Madison Keys continued her debut run in the Australian Open by knocking out 30th seed Tamira Paszek in straight sets this morning.
Keys was composed from the outset on Court Three, earning an early break and using a strong kick serve to claim the opening set by six games to two.
Paszek had no answer for her younger opponent's speed around the court as Keys unleashed 23 winners to wrap up the match in just 65 minutes.
The youngster took the upset win 6-2 6-1 to book her place in the third round, where she will meet fifth seed Angelique Kerber.
