MIAMI, FL, USA - No.12 seed Caroline Wozniacki wasted little time against Sorana Cirstea, wrapping up the rain-delayed night session in straight sets to book a fourth-round battle against Garbiñe Muguruza at the Miami Open, 6-4, 6-2.
"It was definitely a difficult match," Wozniacki told press after the match. "[Cirstea] has a lot of power on her strokes, she plays very flat.
"We know each other from way back, almost 20 years, so it was a good win for me today."
A lengthy rain delay earlier in the day set the schedule back by more than three hours, with Wozniacki's match - which was originally set to begin at 9:30 pm - not starting until almost midnight.
"I just slept in really late today and had a few naps," Wozniacki said, explaining her preparation for the late start. "I just saved all my energy for tonight."
The preparation paid off for Wozniacki, and she started the match firing on all cylinders. Cirstea, who uses an abbreviated service motion as a result of years' worth of shoulder injuries, was quickly broken twice as the former World No.1 built up a 3-0 lead.
Cirstea kept fighting, picking at the Wozniacki forehand and earning one of the breaks back, but she couldn't halt the momentum as Wozniacki powered her way to a 5-1 lead.
With her back to the wall, Cirstea's game finally roared to life, earning another break back and cutting down Wozniacki's lead with excellent ball striking to edge the Dane in baseline battles. She was able to save two set points on her serve, but Wozniacki closed it out on the third time of asking.
The pair opened the second set by trading breaks, with Cirstea emphatically breaking Wozniacki to love. But that was all that the Romanian would get in the second set as Wozniacki righted the ship to accelerate through the next five of six games and take the match.
Wozniacki's victory earns her a fourth-round battle against No.6 seed Garbiñe Muguruza.
"She's a tough opponent, but I'm excited to play another match and be out there once more."
