New York - Beijing Olympic silver medallist Dinara Safina sees room for improvement in her near-flawless current game after swamping Italian Roberta Vinci 6-4, 6-3 to move into the US Open third round on Thursday. "I think it still could be better, especially as I was 4-1 up in the first set and then I let it go to four-all," said the Russian who has reached the finals in six of her last seven tournaments, including the Games and the French Open.
"I was lucky that I held my serve - there is much more room for me to play better."
Safina is on a roll having won her 17th match from her last 18 with titles at Stanford and Montreal over the hardcourt summer.
She took little more than an hours to go through, firing six aces and limiting her unforced errors to 17.
Five-time Wimbledon winner Venus Williams, seeded seventh, set the pace in her family as she hammered Rossana Del Los Rios of Paraguay 6-0, 6-3.
Polish ninth seed Agnieszka Radwanska advanced over Mariana Duque Marino of Columbia 6-0, 7-6 (7-3).
Men's tenth seed Stanislas Wawrinka secured his second straight- sets victory as he rolled American Wayne Odesnik 6-4, 7-6 (8-6), 6-2.
