Roger Federer will likely have to play better if he wants to win a record eighth Wimbledon title but the Swiss had more than enough to beat Dusan Lajovic and reach the third round.
Federer survived a close opening set on Centre Court and from there it was a routine victory for the 35-year-old, who won 7-6 (7/0) 6-3 6-2 in a brisk one hour and 30 minutes.
It is the 15th time Federer has made round three at the All England Club, where he will now face serve-and-volley specialist and world number 30 Mischa Zverev.
Zverev knocked Andy Murray out of the Australian Open in January and while Federer has not dropped a set against his next opponent in two meetings this year, the German will offer a step-up in class.
After playing just 43 minutes before Alexandr Dolgopolov retired in round one on Tuesday, the 18-time major champion will be satisfied to have saved energy again for tougher tests to come.
"I started slow early on, I couldn't get rid of the nerves and struggled to find my rhythm," Federer told the BBC.
"Even when I got back into it after I broke him I struggled in the first set and I was happy to get rid of those nerves, play free tennis, more inspired, and at the end it was very good."
Federer was broken in the first game, punished for three errant backhands, and while he hit back in the fourth it was a disjointed start from the Swiss, full of careless mistakes from the back.
He improved in the tie-break, however, a whipping forehand cross-court the highlight of seven points won in a row. It was only the fourth time in his career Federer had won a grand slam tie-break to love.
Lajovic, previously hitting freely from the baseline, lost his way and when the Serbian framed a smash into the chuckling crowd, the second-set break, and control, was with Federer.
The third set was even more straight-forward as two breaks put Federer in command before a second-serve ace completed a comfortable victory.

Novak Djokovic wins 6-2, 6-2, 6-1 against Adam Pavlasek.#Wimbledon pic.twitter.com/DT16RNPZpS
Blazing afternoon sun caused coach Andre Agassi to seek cover but Novak Djokovic was untroubled again as he brushed aside Adam Pavlasek on Court One.
Three-time former champion Djokovic's first-round match against Martin Klizan was cut short by the Slovakian's retirement early in the second set on Tuesday, and his second outing proved to be another brisk affair, a 6-2 6-2 6-1 win in one hour and 33 minutes.
Agassi emerged to watch the match without a hat, and had to improvise by draping what looked like a tracksuit top over his bald head to stave off the threat of sunburn. He sat in a box at courtside alongside a short-term addition to Djokovic's team, the former top-10 player Mario Ancic whose regular day job is as an investment banker on Wall Street.
Djokovic was taking on plenty of water during each short break between games as the heat prompted some in the crowd to raise umbrellas to deflect the sun rays.
But it was clear from the early stages that while the heat was an issue, 22-year-old Czech Pavlasek would not be troubling him unduly, with an immediate break in the opening game establishing a tone for the match that was never challenged.
Djokovic moves on to bigger challenges, and more serious tests of his form. A double fault from Pavlasek brought this contest to an end, rather aptly.
"It was a very warm day, very hot day," Djokovic told the BBC immediately after coming off court.
"It wasn't easy to play point after point in some long rallies. Midway in the second set we had some long games, but overall from the very beginning I managed to impose my own rhythm and play the game that I needed to play.
"I think I definitely will feel better as days go by. I have been in this particular situation before many times and will try to use the experience knowing what to do on a daily basis to get myself in the right shape, the right state of mind and hopefully the right performance."
Kyle Edmund's dream of reaching the third round was dashed by Gael Monfils on Centre Court.
The British number two had hoped to join compatriots Andy Murray, Johanna Konta, Heather Watson and Aljaz Bedene to make it five British players in the last 32 for the first time in 20 years.
But Edmund, 22, ran into extrovert 15th seed Monfils, who used his full range of power and finesse to send the world number 50 packing 7-6 (7/1) 6-4 6-4.
Grigor Dimitrov gave an exhibition of his enormous talent, striding emphatically into the third round with a 6-3 6-2 6-1 win over Cypriot Marcos Baghdatis.
The 13th-seeded Bulgarian looked less like his "Baby Federer" nickname and more like the Swiss maestro all grown up as he made light work of Baghdatis, a former semi-finalist at the All England Club.
The 26-year-old, who also reached the last four in 2014, has perhaps struggled to live up to his promise as a youngster.
Yet, having reached the semis at the Australian Open earlier this year before losing to Rafa Nadal in a titanic five-set battle, he showed on a sun-baked Court Two that he has the potential and the game to trouble the established favourites.
Big-serving American John Isner lost to Israel's Dudi Sela 6-7(5) 7-6(5) 5-7 7-6(5) 6-3 after almost four hours of play on Court 12.
Since defeating Nicolas Mahut 70-68 in a record-breaking fifth set in 2010, Isner has lost all of his four 5-set encounters at the championships.
