LONDON - There they were, spread across the practice courts on the afternoon before Wimbledon begins: past Grand Slam champions or former No. 1s - Novak Djokovic, Stan Wawrinka, Petra Kvitova, Caroline Wozniacki - and some who aspire to such heights - Eugenie Bouchard, Milos Raonic, Ernests Gulbis.
Djokovic, the 2011 winner at the All England Club and last year's runner-up to Andy Murray, teasingly challenged Wozniacki to hit a serve into a white plastic bag he was holding (she missed, then joked about "too much pressure.") Kvitova tested her heavily wrapped upper right leg. Bouchard, a semifinalist at the last two majors, worked on volleying.
Notably absent was 2013 champion Marion Bartoli, the first woman in 17 years who declined to try to defend her Wimbledon title. Still, Bartoli held the traditional reigning champion's pre-tournament news conference Sunday, when she explained she has zero lingering doubts about retiring at age 28, less than two months after winning her only Grand Slam trophy - and also showed precisely why she quit the sport.
Tugging down the collar of her white top to reveal strips of blue tape providing support for her right shoulder, Bartoli said: "Literally, I can't even lift my arm every morning. It was the same last year and didn't improve. ... So definitely no regrets at all."
She has moved on to other pursuits - TV commentary, launching a shoe line and designing jewelry.
Ah, but Bartoli will always have her Wimbledon championship, and she takes great pride in that.
Wimbledon at a glance
LONDON - A look at Wimbledon, the year's third Grand Slam tennis tournament:
Surface: Grass courts.
Site: The All England Lawn Tennis Club.
Schedule: Play begins today. The women's singles final is July 5; the men's singles final is July 6. There are no matches scheduled for the two-week tournament's middle Sunday, June 29.
2013 Men's Singles Champion: Andy Murray of Britain.
2013 Women's Singles Champion: Marion Bartoli of France.
Last Year: Murray ended the host country's 77-year wait by becoming the first British man since Fred Perry in 1936 to win Wimbledon, beating Novak Djokovic 6-4, 7-5, 6-4. Hitting with two hands off both wings, seeded only 15th, and without a title from any tournament in more than 1 1/2 years, Bartoli beat Sabine Lisicki 6-1, 6-4. It was Bartoli's first Grand Slam trophy - and her last, because less than six weeks later, she surprisingly announced her retirement at age 28, saying her "body was really starting to fall apart."
On Court Monday: No. 1 Novak Djokovic vs. Andrey Golubev, No. 3 Andy Murray vs. David Goffin, No. 6 Tomas Berdych vs. Victor Hanescu, No. 11 Grigor Dimitrov vs. Ryan Harrison; No. 2 Li Na vs. Paula Kania, No. 4 Agnieszka Radwanska vs. Andreea Mitu, No. 6 Petra Kvitova vs. Andrea Hlavackova, No. 8 Victoria Azarenka vs. Mirjana Lucic-Baroni, No. 30 Venus Williams vs. Maria-Teresa Torro-Flor.
"Sometimes, people ask me, 'Who are you?' I just say, 'I'm the Wimbledon champion.' It just speaks by itself," she said. "I don't even need to mention my name."
When the All England Club's suit-and-tie-clad moderator began Sunday's proceedings by intoning, "I have great pleasure in introducing Marion Bartoli, our current ladies' singles champion," the Frenchwoman pumped her fists and smiled broadly.
During the question-and-answer session, Bartoli noted no fewer than three times that she won last year's tournament without dropping a set. She revealed that every couple of days, she'll log on to YouTube and watch a video of the 101 mph (163 kph) ace she hit - a spray of chalk dust proving it was in - to close her victory over Sabine Lisicki in the final.
Her coach for that magical fortnight was Amelie Mauresmo, a former No. 1 and two-time major champion who recently was hired by Murray as he attempts to win a second consecutive title at Wimbledon.
Murray, the first British man in 77 years to earn the championship at the All England Club, will have the honor of opening play Monday on Centre Court, facing Belgium's David Goffin.
"I believe if I play my best tennis, I'll give myself a chance of doing well here; putting myself in a position to win the tournament," the No. 3-seeded Murray said Sunday. "But you can't start off slowly in these tournaments. You need to try and be on it from the first match. I'll be ready for tomorrow."
Other top men in action Monday are the No. 1-seeded Djokovic, 2010 runner-up Tomas Berdych and No. 11 Grigor Dimitrov, who faces American qualifier Ryan Harrison. Women on the schedule include five-time champion Venus Williams, No. 2 Li Na, 2012 runner-up Agnieszka Radwanska and No. 8 Victoria Azarenka, who is coming off a left foot injury.
The last woman to skip a title defense at Wimbledon was Steffi Graf in 1997, shortly after knee surgery.
Bartoli left tennis primarily because of "too many question marks" about her health.
But there are other parts of life on tour she does not feel nostalgic about.
"I don't miss every morning having to wake up and not being able to lift my arm; having my whole body terribly sore; having to travel; pack and unpack; all the practice time you have to book; make sure you're just having your schedule ready," she said.
Apparently, word of her retirement last August did not make the rounds everywhere. As the start of the French Open approached last month, Bartoli said, people stopped her on the streets of Paris to say they hoped she would fare well in that tournament.
Even Sunday, wandering around the local village, this sort of exchange happened, according to Bartoli:
"So how do you feel? Do you feel it's going to be hard to defend your title?"
"Um, not really, because I'm not going to defend it."
