London - Garbine Muguruza stepped up her bid to return to the Wimbledon final as the world No 15 raced into the fourth round with a 6-2, 6-2 victory over Romania's Sorana Cirstea on Saturday.
Muguruza became the first Spanish woman to reach the Wimbledon title match in 19 years when she was beaten by Serena Williams in the 2015 final.
Muguruza, who won her first major title at the French Open last year, is through to the last 16 at Wimbledon for just the second time and has yet to drop a set this year.
She needed only 70 minutes to see off Cirstea and faces world number one Angelique Kerber or American Shelby Rogers for a place in the quarter-finals.
Cirstea, the world No 63, cut a subdued figure as she returned to singles action following the horrific knee injury suffered by her opponent Bethanie Mattek-Sands in the previous round on Thursday.
