Caroline WozniackiThe No. 1 seed, Caroline Wozniacki, cruised to an easy win over Chelsey Gullickson, 6-1, 6-1 in her first round match at the 2010 U.S. Open Tuesday.

Wozniacki of Denmark is currently ranked No. 2, but was given the No. 1 seeding when World No. 1, Serena Williams, withdrew because an ongoing foot injury.

Wozniacki had little trouble against American wildcard, Gullickson. The two women didn’t meet on court until 12 a.m. after lengthy previous matches at Arthur Ashe pushed their start time into the far reaches of night. Gullickson, a rising junior at University of Georgia and the 2010 NCAA singles champion, seemed to be thrown off by the late start and the pressure of performing on such a big stage. While she was returning Wozniacki’s serves and battling it out on the baseline exhibiting a promising powerful forehand, Gullickson was her own worst enemy on the court, logging 30 unforced errors and four double faults.

Wozniacki for her part was strong and steady, only logging six winners and two aces, but playing patiently and allowing to Gullickson make mistakes.
