Spanish star Rafael Nadal, who made an early exit from the All England Club, is one of the male players most mentioned on Facebook posts during Wimbledon, the social-networking site said.
About 11.6 million posts around the world have either included comments, mentions or "Likes" of Nadal.
Swiss great Roger Federer, who failed in his bid to defend his title at Wimbledon, and Serbian world No. 1 Novak Djokovic ranked second and third, respectively, on Facebook.
Among the women, Russian star Maria Sharapova is the tennis player most mentioned on Facebook, followed by American Serena Williams.
The 27-year-old Nadal drew the most comments for his stunning first-round loss at Wimbledon to Belgium's Steve Darcis, the world No. 135.
The loss marked the first time that Nadal fell in the first round of a Grand Slam event.
The Spaniard was knocked out of Wimbledon by Czech Lukas Rosol in the second round last year.
The Spaniard's loss at Wimbledon last year was followed by a seven-month absence from the ATP Tour due to a knee injury.
Nadal, who won his 8th French Open title on June 9, took the title at the All England Club in 2008 and 2010, and has won 12 major championships.
The United States is the country where tennis has the most followers on Facebook. EFE
