A look at Wimbledon, the year's third Grand Slam tennis tournament:
Surface: Grass courts.
Site: The All England Lawn Tennis and Croquet Club.
Schedule: Play begins Monday. The women's singles final is July 2; the men's singles final is July 3. There is no play scheduled for the two-week tournament's middle Sunday, June 26.
2010 Men's Singles Champion: Rafael Nadal of Spain.
2009 Women's Singles Champion: Serena Williams of the United States.
Last Year: Nadal beat Tomas Berdych of the Czech Republic 6-3, 7-5, 6-4 for his second Wimbledon title. Berdych had eliminated six-time champion Roger Federer in the quarterfinals. Williams won her fourth Wimbledon singles championship and 13th Grand Slam title overall by beating Vera Zvonareva 6-3, 6-2 in the final.
Key Statistic: 26-2 - Nadal's record at Wimbledon from 2006-10, reaching the final all four times he's entered the tournament in that span. He lost to Federer in the 2006 and 2007 finals, then won the 2008 and 2010 championships; Nadal didn't play at Wimbledon in 2009 because of knee tendinitis.
Two Key Returns: The Williams sisters are entered in Wimbledon after lengthy injury absences. Serena missed nearly a full year before coming back at a grass-court tuneup tournament in Eastbourne, England, this month; Venus was out since January until returning at that same event. They have combined to win nine of the 11 Wimbledon women's singles titles since 2000.
Fancy Meeting You Here: John Isner of the United States and Nicolas Mahut of France were drawn to play each other in the first round this year - an oddly coincidental rematch of their record-breaking, 11-hour, 5-minute first-round match in 2010, which Isner won 70-68 in the fifth set. There is a plaque on Court 18 commemorating last year's marathon.
When It Rains: As of 2009, Centre Court is fitted with a retractable roof, which allows matches to be played during wet weather. Monday's forecast calls for rain.
Prize Money: Total is 14.6 million pounds (about $23.5 million), with 1.1 million pounds (about $1.77 million) each to the men's and women's singles champions.
TV: ESPN2 (starting Monday), Tennis Channel (starting Monday), NBC (starting June 25).
