Top seed Caroline Wozniacki made comfortable progress into the second round of the US Open with a 6-1 6-1 victory over American wild card entrant Chelsey Gullickson.
The 20-year-old Wozniacki, seeded first here due to the absence of Serena Williams with a foot injury, arrived at Flushing Meadows in excellent form having won in Montreal and New Haven in the space of six days last week.
Wozniacki saved a break point in game one and it proved to be the first of six points she won in a row en route to breaking Gullickson, setting the tone for the first set which began just before midnight in New York.
A long forehand from the American gave Wozniacki a second break in the sixth game and allowed the Dane to serve for the first set, and she wrapped it up with the match only 30 minutes old.
Wozniacki broke Gullickson again in the opening game of the second set and a further breakthrough in the fifth – with her opponent committing a host of unforced errors – put her well in control.
Gullickson earned break-point chances in game six but the seeded player snuffed them out and held with a brilliant passing shot, before another break ended the match.
Wozniacki will be aiming to go one better here than she did last year, when she lost to Kim Clijsters in the final.
Kai-Chen Chang is up next for Wozniacki in the second round and the Dane is 9/2 to beat Chang and secure her first US Open title.
Despite being number one seed, Wozniacki isn’t favourite for the championship. See the latest US open tennis betting markets here.
