LONDON: Top seed Amelie Mauresmo stormed through to the Wimbledon fourth round with a confident 6-1 6-2 victory over Australian Nicole Pratt on Saturday.   
 
The Frenchwoman, a semifinalist on each of her last three visits to the All England Club, brushed aside 33-year-old Pratt with some expert grasscourt tennis.   
 
Mauresmo sealed a 59-minute victory on court one with an ace and has only lost nine games in her first three matches.   
 
She plays Serbia's Ana Ivanovic in the last 16.
