Federer and Vavrinec first met at the Olympic Games in 2000
World number two Roger Federer has married his long-term girlfriend Mirka Vavrinec in Basle.
"It was a beautiful spring day and an incredibly joyous occasion," the 27-year-old Swiss told his website.
The couple, who are expecting their first child, met when they competed at the 2000 Olympic Games in Sydney.
Next week, Federer is due to take part in the Monte Carlo Masters - the opening clay-court tournament of the season - after he was given a wildcard.
A three-time finalist, Federer originally chose to skip the event for scheduling reasons but has had a change of heart as he tries to find some form.
Federer has not won a tournament since October and played poorly in his most recent loss to Novak Djokovic in Miami.
The Swiss has finished runner-up three times in Monte Carlo, losing 7-5 7-5 to Rafael Nadal in last year's final.
World number one Nadal will be going for a record fifth straight title this year.
American Andy Roddick will be the only member of the world's top 10 missing at the clay-court tournament.
