Australia’s Sam Stosur copped the brunt of the Serena Williams comeback, losing in straight sets 7-5 6-3 in the last 16 of the Sony Ericsson Open.
In their first rematch since the 2011 US Open Final in which Stosur won, Williams thoroughly outplayed the Australian on her home soil.
It is Williams’s first tournament since January when she injured her left ankle.
Stosur broke Williams’ serve in the first set of each game but did little else to prove she belonged in the tournament’s quarterfinals.
Williams served an impressive 20 aces to the sixth seeded Stosur and converted four of 13 break points opportunities in her fifth win from eight contests against Stosur.
She has won the Miami tournament five times and the win marked her fifth consecutive victory against top-five players.
Stosur hasn’t exactly lit the world on fire since her maiden Grand Slam victory at Flushing Meadows last year and her latest loss is another in a growing list of disappointing 2012 efforts. She lost in the third round of last month’s BNP Paribas Open in Indian Wells, was defeated by Jelena Jankovic in February at the Dubai Open, was shellacked in the final of the Qatar Open and was embarrassed in the first round of the Australian Open in January.
In the match earlier, Maria Sharapova edged out fellow Russian Ekaterina Makarova to also advance to the quarterfinals, 6-4 7-6 (7-3).
Sharapova, who overcame 11 double-faults in the victory, will now play the winner of the Li Na and Sabine Lisicki, being played now.
