Roger Federer began grand slam life as a father of four with a supremely comfortable victory over Lukas Lacko in the first round of the French Open.
The 2009 champion arrived in Paris this week with his expanded family in tow following the birth of his second set of twins, Lenny and Leo, nearly three weeks ago.
His four-year-old daughters, Charlene and Myla, were in his box on Court Philippe Chatrier for the start of his 6-2 6-4 6-2 win against Slovakian Lacko.
Federer lost his first match since the birth of his sons in Rome to Frenchman Jeremy Chardy but was never troubled on Sunday, perhaps not surprisingly given Lacko has not won a match on clay for three years.
He had not even contested a match on the surface since Roland Garros last year and was forced to fight hard for the games he did win.
Lacko saved six of the 11 break points he faced but did not create a single one on the Federer serve, winning just nine points on the fourth seed's serve in the match.
Federer won five games in a row to win the first set and his only frustration would have been that it took him an hour and 24 minutes to wrap up victory.
One of the most intriguing first-round match-ups pitted eighth seed Milos Raonic against 19-year-old Australian wild card Nick Kyrgios.
The teenager looks set to have a bright future but he found Raonic too tough, the Canadian winning 6-3 7-6 (7/1) 6-3.
Not surprisingly, Federer, who extends his record by playing in a 58th consecutive grand slam tournament, was in a very positive mood after the match.
The Swiss said: "Everything is great.
"I'm happy I got off to a good start for the tournament here in Paris. There's always that little bit of a feeling that if you don't feel well, if the opponent plays great, whatever happens, you could lose early.
"So I was happy getting early signs out of the match that I was actually playing well and I was going to get my chances I was looking for. I'm very pleased with the outcome of the match.
"My personal life, as we know, it's all great, so I'm happy the family is here."
Federer, meanwhile, does not agree with the bookmakers that Novak Djokovic is the favourite for the men's title ahead of eight-time champion Rafael Nadal.
"Rafa is the favourite, and then Novak, and then the rest," he said. "It's very clear."
Sixth seed Tomas Berdych, sporting an eye-catching floral shirt, made smooth progress through to the second round with a 6-3 6-4 6-4 win over Peter Polansky of Canada while Mikhail Youzhny and Radek Stepanek both recovered from two sets down.
Twenty-second seed Jerzy Janowicz broke a nine-match losing streak stretching back to February with a 6-1 6-4 6-7 (6/8) 6-4 victory over Victor Estrella Burgos.
Estrella Burgos, a 33-year-old from the Dominican Republic, was making his first appearance in the main draw of a grand slam.
Tenth seed John Isner prevailed in three tight sets against Pierre-Hugues Herbert and could play fellow marathon man Nicolas Mahut in round two.
Eight-time champion Nadal begins his campaign on Monday, rather surprisingly not on Chatrier but on Roland Garros' second court, Suzanne Lenglen, where he will play US wild card Robby Ginepri.
Djokovic and Australian Open champion Stan Wawrinka are on Chatrier, against Portugal's Joao Sousa and Guillermo Garcia-Lopez, respectively.
