Roger Federer needed just 12 games to advance to the Wimbledon second round.
Afterward, Federer revealed essential elements to Big 4 success in four words.

"I think mind, fitness, tenacity, then talent as well," Federer said. "Put them all together, it's hard to crack us four consistently down. If you beat one of us, you might not beat the next guy."
Launching his quest for his first Wimbledon title since 2012, the seven-time champion held a 6-3, 3-0 lead when Alexandr Dolgopolov retired with a foot injury.
That early Centre Court retirement followed Novak Djokovic winning eight of 11 games before Martin Klizan pulled the plug on their opener.
Federer believes disparate playing styles are one reason why the Big 4 have combined to win 14 consecutive Wimbledon championships.
"We play all very different," Federer said. "I don't know, pick me, Rafa, Novak, how different we all play for one another. For a player to run through the three of us is extremely difficult. If you're ranked lower than us, that's who you have to beat maybe on the way to win the tournament. It just seems pretty rough."
Former world No. 1 Martina Hingis famously said "it's easier to be the hunter than the hunted."
Federer, Hingis' former mixed doubles partner, said he loved life at the top of the world rankings.
"It's better to be No. 1, yes if I could choose," Federer said when asked if it was more enjoyable to play as the world No. 1 or to face the world No. 1.
"Because it feels better to be No. 1 than No. 5. I mean, I'm happy right now in the situation I find myself in," Federer said. "I'm healthy. I'm happy. I'm back at Wimbledon. I just won my first round.
"The times when I was world No. 1, it felt great. It's sort of achieving the impossible, showing up when everybody feels you're the favorite, everybody believes that you should win or have to win. I don't know, I kind of enjoyed that part of playing. But then again, it's secondary to the love for the game I have, how much I love winning. Rankings get shoved a little bit aside for me at this stage of my life."
