Wimbledon runner-up Agnieszka Radwnaska and former world number one Ana Ivanovic breezed into the US Open second round on Tuesday as both women look to bury their woeful Flushing Meadows records.
Polish second seed Radwanska and Ivanovic, the 12th-seeded Serb who was French Open champion in 2008, have never got beyond the fourth round in New York but have been quarter-finalists at the other three majors.
Radwanska, whose New York best came in 2007 and who lost in the second round in 2011, began her campaign with a 6-1, 6-1 win over Nina Bratchikova with the Russian's challenge undone by 28 unforced errors.
Next up for Radwanska, who became the first Polish woman to make a Grand Slam final when she lost to Serena Williams at Wimbledon last month, is Spain's Carla Suarez Navarro.
"It's always a bit harder (coming in as second seed) because people expect you to play well and go far in the tournament," said 23-year-old Radwanska, who only needed 54 minutes to progress on Tuesday.
"But I am just trying not to really think about pressure. I don't really have many points to defend from last year. At least this is the good thing."
Radwanska also admitted that a right shoulder injury is still causing her some concern.
"It's different when I'm playing matches or I'm just practicing and not pushing that much. I'm really taking care of it right now," said the Pole, who retired from a first-round match in New Haven last week to protect the injury.
Ivanovic -- whose fourth-round appearances came in 2007, 2010 and 2011 -- defeated 17-year-old Ukrainian qualifier Elina Svitolina 6-3, 6-2 and goes on to face Sweden's Sofia Arvidsson.
Svitolina, the 2010 French Open junior champion, was one of nine teenagers in the main draw.
Arvidsson reached the second round by seeing off 41-year-old Kimiko Date Krumm of Japan 6-4 6-2.
Asian hopes took a further battering when Chinese 32nd seed Peng Shuai tumbled out 7-6 (7/5), 6-1 to Russia's Elena Vesnina.
Later Tuesday, defending champion Novak Djokovic gets his campaign underway against Italy's Paolo Lorenzi, who is making his US Open debut at the age of 30 and has yet to win a Grand Slam match.
World number two Djokovic beat Rafael Nadal in last year's final after coming from two sets down and saving two match points against Roger Federer in the semi-finals.
Three-time women's champion and Olympic Games gold medallists Serena Williams, last year's runner-up, faces American compatriot Coco Vandeweghe.
Venus Williams, the 2000 and 2001 winner, also has an all-American match-up with wildcard Bethanie Mattek-Sands.
