NEW YORK -- Back on the Grand Slam stage, Eugenie Bouchard returned to her winning ways.
The seventh-seeded Bouchard routed Olga Govortsova 6-2, 6-1 on Tuesday in the first round of the US Open. The last time she played at a major tournament, the 20-year-old made history: the first Canadian to reach a Grand Slam final.
But in the Wimbledon title match, she was swept away by Petra Kvitova 6-3, 6-0, and things didn't go much better in her three hard-court tuneups for the US Open. Bouchard won just one of her four matches, including an upset loss in her opener in her home tournament in Montreal.
But against the 117th-ranked Govortsova, she had little trouble. Govortsova, who has been ranked as high as 35th, had won just two main draw WTA matches this year.
Ana Ivanovic was feeling good about her game coming into the US Open, and it showed Tuesday. The eighth-seeded Serb beat American Alison Riske 6-3, 6-0. Ivanovic has won 48 matches this year, more than anyone else on tour.
The 2008 French Open champion has struggled to get back to that level but finally seems to be inching closer. She returned to the top 10 this month for the first time in more than five years.
"The confidence is on a high level," she said. "I had a great season behind me."
The 24-year-old Riske made a breakthrough at last year's US Open, reaching the fourth round after an upset of Kvitova. She reached a career-high ranking of No. 40 this summer.
Ivanovic upset Williams to reach the Australian Open quarterfinals. She was playing well heading to Roland Garros but lost in the third round to Lucie Safarova.
In her last tuneup before coming to New York, Ivanovic beat Sharapova in the semifinals in Cincinnati before losing to Williams in the title match.
Svetlana Kuznetsova lost her first-round US Open match for the first time since 2005, the year she was the tournament's defending champion. Kuznetsova, seeded 20th this time, was beaten 3-6, 6-2, 7-6 (3) by 82nd-ranked Marina Erakovic of New Zealand.
Williams will play the night session at Arthur Ashe Stadium. She faces American teen Taylor Townsend, who's making her US Open debut.Information from The Associated Press was used in this report.
