Roger Federer is safely through to the second round of Wimbledon following an extremely comfortable victory over world number 88 Damir Dzumhur.
The 33 year old, chasing an eighth title at the All-England club in his 63rd consecutive major appearance, was never troubled by his Bosnian opponent in sweltering conditions on centre court and easily progressed 6-1, 6-3, 6-3 after just one hour and eight minutes.
After the win, Federer told the BBC: "There is always focus. I was trying to play as freely as possible without losing a set. I played aggressive, he changed his game a bit to make it difficult. I am very happy to win like that.
"The start of the tournament is normally overcast and the grass feels slippy. The court is on the harder side."
Over on court one, 10th seed Rafael Nadal was given a slightly tougher test by Thomaz Bellucci, but never looked like losing on his way to a 6-4, 6-2, 6-4 success. A good start from the two-time champion, but he will need to improve rapidly if he is to have a chance of beating the likes of Federer, Novak Djokovic and Andy Murray.
Defending women's champion Petra Kvitova, meanwhile, took just 35 minutes to dispatch of Kiki Bertens in a ruthless 6-1, 6-0 victory.
"It was a great feeling returning to Wimbledon," she said.
"I was very nervous but when I was standing on the court, the people were clapping, the atmosphere was brilliant. I am really glad how I played as well. Nerves are important, they are healthy. I like them. I was sick a few days ago but still played very well.
"There are so many great opponents here so I still have to focus on myself, that's the most important thing."
Andy Murray is currently playing his first-round contest against Mikhail Kukushkin, while Heather Watson has beaten Caroline Garcia in three sets.
