EASTBOURNE, England (AP) Making her return to competitive tennis after having blood clots in her lungs and two foot surgeries, Serena Williams slipped and fell in the final game of the match at Eastbourne on Tuesday.
The 13-time Grand Slam champion recovered from a slow start to win her first match after nearly a year off the WTA tour, rallying past Tsvetana Pironkova 1-6, 6-3, 6-4 in the first round.
She fell at the baseline, but got up immediately and carried on the point, although she lost it. Williams said was briefly worried about tweaking the right foot that was in a cast for 10 weeks.
I felt a little something. I got a little nervous,'' Williams said.
I was like, 'Oh.' Then I thought this is grass. You know, you're really moving. You're stopping, you're going. If I can survive this, especially with this long match, I'll be good.''
The 13-time Grand Slam champion initially looked nothing like the player who lifted the 2010 Wimbledon trophy in her last tournament. Her movement was uncertain, and she appeared not to trust her groundstrokes or her usually dominant serve.
She held for the first time at 5-0 down, with the help of her first ace of the match. Williams steadied herself and reeled off the first three games of the second set to take control. Despite squandering a 2-0 lead in the decider, she broke again to secure the win.
How difficult was the first set? It wasn't too difficult, it wasn't long,'' Williams said.
It was over really fast and I thought, well hopefully I can get some momentum. I think I was just a little anxious and missing a tremendous amount of shots.''
Williams hasn't played since July after cutting her foot on glass at a restaurant. She had two foot surgeries and later was diagnosed with pulmonary embolisms in her lungs. By the time she served out the match after 2 hours on court, the 29-year-old American was breathing heavily and given a warning by the umpire for taking too much time between points.
Williams said she thought she should have been given a pre-warning, and wondered ``whether had I been gone so long that they changed it.'' But despite the struggle, Williams said she enjoyed her return.
After everything I've been through, it's all fun to me now,'' she said.
It's all a bonus.''
And not breaking a nail during the fall was a plus.
It's definitely not cool on my nails if I fall,'' she said.
I can potentially break one and that makes me really upset. I have three weeks to get through without breaking a nail.''
Next up is a repeat of the 2010 Wimbledon final against top-seeded Vera Zvonareva, a 6-3, 6-3 winner over British wild card Heather Watson.
She's a great player and I have nothing to lose,'' Williams said.
I'm going to go in there and do what I can do. Whatever happens, happens.''
It looked like a short-lived return when Williams dropped the first set in 27 minutes.
Wearing a pink dress that she said was inspired by French actress Brigitte Bardot, Williams walked out to the song ``I'm The World's Greatest,'' chosen by organizers. The 29-year-old American was given a warm welcome as she was introduced to a three-quarters full stadium.
But she looked unsure in the warmup and it spilled over into the match. Her sister Venus, who returned from a hip injury after five months away, began her match Monday with two double-faults. Serena opened her first service game with one of her own.
Pironkova, who reached the semifinal at Wimbledon last year but had won only four matches this year, used fierce groundstrokes to take an early lead.
After trailing 4-0, Williams smacked her racket into the turf in disgust. On winning her first game to make it 5-1, the former top-ranked player heard the rare sound of sympathetic applause.
The unseeded Bulgarian then took the set with a forehand winner.
Soon Williams began to look - and sound - more like her old self. She increasingly greeted her winners, and an improving first serve, with determined cries of ``c'mon.''
Leading 5-3 in the second set, she fell 0-30 down but responded with a 120 mph ace down the middle and a 114 mph ace out wide.
Williams was still below her best in the third as Pironkova's flat groundstrokes continued to do damage. She rallied to 2-2, but the unseeded Williams immediately broke again and served it out at 5-4.
In other matches, Ana Ivanovic advanced to a second-round meeting with Venus Williams with a 6-4, 6-3 win over Julia Goerges of Germany.
The former No. 1-ranked Serb won her last two events of 2010, but she has struggled and lost in the first round in four of her 10 tournaments this season. Her semifinal last week in Birmingham was her first of the year.
I don't expect myself to go out there and play great every match,'' Ivanovic said.
I just expect myself to work hard. But it's hard. I do have to think about going back to basics for a moment and trying to get the practice in, trying to stay healthy and trying to stay basically on top of small things.''
Defending champion Ekaterina Makarova labored to a 6-1, 3-6, 6-4 win over Croatian qualifier Mirjana Lucic. French Open runner-up Francesca Schiavone advanced with a 7-6 (7), 6-1 win over Kaia Kanepi.
In the men's tournament, top-seeded Jo-Wilfried Tsonga won his first round-match against Denis Istomin 6-2, 7-5, a day after losing the delayed Queen's final to Andy Murray.
A foot injury forced former Wimbledon champion Lleyton Hewitt to retire from his match against Olivier Rochus while trailing 6-2, 3-0, while fourth-seeded Guillermo Garcia-Lopez was beaten 6-3, 6-4 by Somdev Devvarman of India.
Sixth-seeded Kevin Anderson defeated Alexander Slabinsky of Britain and American qualifier Donald Young beat Daniel Cox 6-1, 7-5.
