Williams, Ivanovic, Mauresmo, Kuznetsova, Chakvetadze, Vaidisova advance
Ana Ivanovic beat Rossana de Los Rios of Paraguay 6-1, 6-2 in less than an hour in her first match since winning the French Open and taking over the No. 1 ranking. The Serb never faced a break point and ripped 13 baseline winners.
"Coming as the top seed, lots of people just expect you to win," Ivanovic said. "You have to work hard, especially on grass. Everything is happening so fast."
Williams made a fashion statement when she came out onto Court 1 wearing a white, belted, thigh-length raincoat, or Mackintosh. But there was no rain in sight, so she hung the jacket on her chair. Kanepi, meanwhile, wore dark sunglasses throughout the match.
"You know, I absolutely love trench coats," Williams said. "Now I have a wonderful white coat I can wear on the court and also in New York for those rainy days. It's ladylike and goes perfect with my personality. It's very light. It's just delectable."
Williams, whose Wimbledon wins in 2002 and '03 are among her eight major titles, struggled in the first set. She fended off five break points against the French Open quarterfinalist.
The turning point came at 5-5 when Kanepi had a break point for 6-5. Williams attacked and put away a forehand volley smash, letting out a shout and pumping her fist. She held serve and Kanepi double-faulted on set point in the next game. Williams was in command throughout the second set.
"Today definitely was not an easy match," Williams said. "She was playing unbelievable. I felt like she wasn't making any errors. I just felt like I just had to hang in there and stay positive."
The match was the first for one of the Williams sisters since they lost on the same day in the third round at the French Open. They flew from France to Florida and prepared for grass by hitting on hard courts.
The unorthodox preparation for Wimbledon is standard for the sisters and not to be questioned -- they've won the title six of the past eight years.
"We just go home and practice in the hot sun," said Williams, who is seeded sixth. "We're so ready to leave Florida. We're like, 'We're going to do anything we can to stay at the tournament as long as we can so we don't have to go back in that heat.'"
While Williams was happy to have won her opening test in straight sets, Anna Chakvetadze had to fight tooth and nail to survive.
Eighth seed Chakvetadze stormed back from 5-2 down in the third set to beat Canada's Stephanie Dubois 2-6, 6-1, 8-6.
Ivanovic, who reached the semifinals here last year, had far too much power for her 103rd-ranked opponent, belting winners at will from the back of the court.
"Becoming No. 1 takes more pressure, but also you have to see pressure for what it is," Ivanovic said. "It's a reflection of your own ambition. If you see it as a positive thing, it means that you put yourself in a position to do something memorable. So if you look at it that way, it can be very motivating."
Ivanovic, 20, wrapped up the first set with little answer from the 32-year-old Paraguayan. Her blistering groundstrokes off both sides proving too powerful. De Los Rios held her opening serve to take an early lead in the second set but Ivanovic was never troubled.
De Los Rios, who was watched by her 11-year-old daughter, Ana Paula, from the players' box, prolonged the end slightly when she successfully challenged an Ivanovic serve on match point, which was called an ace.
The respite was short-lived, however, and the Serbian favorite wrapped up the match to claim her place in the second round, where she will meet France's Nathalie Dechy.
"I think I played quite well today, considering it's the first match. Especially first match on the grass. It's quite a big change but I was very happy to be back on Centre Court," Ivanovic said.
"Today's match was a tough one. I had to stay focused. I served really well and that's something that really help me. I was quite aggressive, so I was pleased with the way I played," she added.
Vaidisova, a quarterfinalist here 12 months ago, enjoyed a brisk workout on Court 19 on a warm day at the grass-court Grand Slam.
She will next face Australian wild card Samantha Stosur.
Despite the sunny weather, it was another in a series of dismal days for U.S. tennis. The only American woman to join Williams in the second round was Bethanie Mattek, who rallied past Severine Bremond 5-7, 6-0, 6-1.
Plenty of seeded players fell by the wayside, including Swiss 12th seed Patty Schnyder, Russian 19th seed Maria Kirilenko, French duo Alize Cornet (No. 17) and Virginie Razzano (No. 27), and Slovakian No. 30 Dominika Cibulkova.
