Two-time finalist Li Na raced into the semi-finals of the Australian Open as she produced a ruthless display to beat Flavia Pennetta.
The fourth seed from China broke the Italian in the first game of the match, following it up with two more to lead the first set 5-0.
Pennetta, the 28th seed, stopped the rot with a break of her own but Li still took the set 6-2.
And the second set was equally one-sided as Li eased to a 6-2 6-2 victory.
