LONDON - Not even a return to Wimbledon could pull Eugenie Bouchard out of her tailspin.Bouchard, who was runner-up at Wimbledon last year, fell in the opening round, losing 7-6 (3), 6-4 to Duan Ying-Ying — a 117th-ranked Chinese qualifier who was playing at Wimbledon for the first time and had never before won a Grand Slam match.Bouchard seemed to be the new star of women's tennis last year when she reached at least the semifinals at the first three Grand Slam tournaments. She made a stirring run to the Wimbledon final, where she lost to Kvitova.This year, the 21-year-old Canadian has lost 12 of 14 matches and also went out in the first round at the French Open.Bouchard, who served 10 double-faults on Tuesday, said she was still hampered by the abdominal injury that forced her to retire from last week's grass-court tournament in Eastbourne. She said she had been advised not to play at Wimbledon, but decided she couldn't pass up the chance."I felt very unprepared for this match," Bouchard said. "I hadn't practiced that much. My timing was off. ... It's not an excuse because I chose to play."Fellow Canadian Vasek Pospisil fared better then Bouchard. Vancouver's Pospisil beat France's Vincent Millot 7-6 (2), 3-6, 6-7 (4), 7-6 (4), 6-3.A few minutes after Bouchard's defeat, the player she beat in last year's semifinals also was eliminated.No. 3 Simona Halep became the highest seeded player eliminated so far, tumbling 5-7, 6-4, 6-3 to 106th-ranked Jana Cepelova of Slovakia. The Romanian, who also reached the French Open final last year, was treated for blisters on her left foot at the end of the first set. Halep, who is not considered a grass-court specialist, hurt her chances with seven double-faults and 34 unforced errors.Earlier, defending women's champion Petra Kvitova and former men's winners Roger Federer and Rafael Nadal all won their first-round matches at Wimbledon in straight sets and in rapid-fire fashion.Of the three, only Nadal lost serve and the big names imposed themselves with ease on Day 2 of the grass-court Grand Slam as London basked in warm, sunny conditions.In keeping with Wimbledon tradition, Kvitova had the honour of playing the first match on Centre Court on the second day as the reigning women's champion.The second-seeded Czech wasted no time in reasserting her dominance on her favourite court, overpowering Kiki Bertens of the Netherlands 6-1, 6-0 in just 35 minutes.Kvitova won 28 of 29 points on serve, with the only blemish coming when she double-faulted on the first point of the final game, hitting a 93 mph (150 kph) second serve just wide. She won the next four points, finishing — appropriately — with a service winner.While Kvitova was happy to sail through so quickly, she felt bad for her parents, who were guests in the Royal Box and got to see their daughter play for barely more than half an hour."I have to say sorry to them," she said, smiling. "I think they are happy anyway."Federer, the seven-time men's champion, followed Kvitova on Centre Court and also made quick work of his opponent. The second-seeded Swiss needed just 68 minutes to dispatch 88th-ranked Damir Dzumhur of Bosnia 6-1, 6-3, 6-3.Federer, bidding to become the first man to win eight Wimbledon titles, broke five times and never faced a break point."I was happy I played aggressive," he said. "I must say I'm very happy, always, to win like that."Federer, who has won 17 Grand Slam titles, is playing in his 63rd consecutive major."Somehow the streak is still alive and I'm also very proud of the fact that I never retired from a match once it started," he said. "Those two stats I care about and hope I can keep them up for the remainder of my career."Nadal, the two-time champion, coasted to a 6-4, 6-2, 6-4 win over Thomaz Bellucci of Brazil on Court 1. He hopped in the air and pumped his fist after completing the victory."Here the feeling in Wimbledon is so special, and playing on grass, too," Nadal said. "So always is very emotional when you hit some good shots in this beautiful club."Nadal, who lost in the first round of the Wimbledon warm-up at Queen's Club and has slipped to No. 10 in the rankings, was broken twice and was credited with fewer winners (21) than unforced errors (23) but still was never seriously troubled."In general, it was a very positive victory," the Spaniard said. "Straight sets. Not bad feelings."Another former champion, 2013 winner Andy Murray, was playing the third match on Centre Court, facing Mikhail Kukushkin of Kazakhstan.In another one-sided women's match, 10th-seeded Angelique Kerber swept fellow German Carina Witthoeft 6-0, 6-0 — the third "double bagel" in two days.On Monday, both Venus Williams and Andrea Petkovic won their matches 6-0, 6-0. Those were the first double bagels at Wimbledon in six years.Kerber said the scoreline of the 44-minute match was misleading."I think it was a good match for me," she said. "Carina was playing not bad, actually. So the games (were) not like 40-0. It was very close, actually."Other men's winners Tuesday included No. 13 Jo-Wilfried Tsonga, No. 20 Roberto Bautista Agut, No. 22 Viktor Troicki, No. 23 Ivo Karlovic, No. 25 Andreas Seppi and No. 30 Fabio Fognini.Jack Sock, the 13th-seeded American, was knocked out by Sam Groth of Australia, 6-3, 3-6, 6-3, 6-3.Among the women, No. 17 Elina Svitolina and No. 20 Garbine Muguruza advanced to the second round.
