NEW YORK — Third-seeded Agnieszka Radwanska needed more than an hour to capture the second set of her 6-0, 7-5 victory over Maria-Teresa Torro-Flor in the second round of the US Open on Wednesday (Thursday, Manila time).
Radwanska rolled through the first set in 21 minutes, dropping only seven points. It took her one hour and six minutes to win the second set against her 103rd-ranked opponent from Spain.
Radwanska, the Wimbledon runner-up last year and a semifinalist at the All England Club this year, has never made it past the fourth round in seven previous appearances at Flushing Meadows.
She finished with only 10 unforced errors, compared to 38 for her opponent.
Fifth-seeded Li Na of China also advanced with a 6-2, 6-2 victory over Sofia Arvidsson of Sweden.
Li, the 2011 French Open titlist, hit 29 winners to only four for her 100th-ranked opponent.
Li is in the third round of the US Open for the fifth time and could face Britain's Laura Robson, who beat her in the third round last year at Flushing Meadows.
