There were landmark wins for Rafael Nadal and Novak Djokovic in the second round of the French Open while a familiar face is showing form again at last.
Nadal became the eighth player to record 200 grand slam victories, thumping Argentina's Facundo Bagnis 6-3 6-0 6-3.
After losing the first two games, Nadal won 18 of the next 22 and arrives in the last 32 having barely broken sweat.
The nine-time champion said: "I didn't even know, so the most important thing is a victory in the second round more than the 200 victories. That's only another number."
World number one Djokovic had a tougher time against Belgian qualifier Steve Darcis but avoided dropping a set in a 7-5 6-3 6-4 victory.
It was his 50th win at Roland Garros and made him the third player in the Open era, after Roger Federer and Serena Williams, to rack up a half-century at every slam.
Djokovic said: "I'm pleased to get the job done in three sets but there were things that I definitely didn't like in my game today. Too many unforced errors from the first or second shot in the rally.
"It's kind of expected at the beginning that you are a bit rusty on the court, and hopefully things will get better."
Few players have been as up and down over the past decade as Ernests Gulbis.
The Latvian is into the third round at a slam for the first time since his run to the semi-finals here two years ago.
Gulbis beat Federer and Tomas Berdych before losing to Djokovic in 2014 and finally made the breakthrough into the top 10.
But, instead of being the start of great things for the talented but mercurial 27-year-old, he promptly sank like a stone.
Now ranked 80, Gulbis is philosophical about the fluctuations in his career after overcoming shoulder and wrist problems.
"I was a couple of times already in the spotlight and a couple of times already it's faded, so it wasn't the first time," he said after a 6-2 7-5 6-3 victory over 26th seed Joao Sousa.
"I know spotlight, I know fading away, I know playing centre court, I know playing Court 18 here where nobody brings you to court and where your coaches don't get a seat on your court. It's okay."
Gulbis is in Paris without a coach having split from his long-time mentor Gunter Bresnik, who is now concentrating on travelling with rising star Dominic Thiem.
For a long time, Gulbis was the senior man and 22-year-old Thiem the apprentice, but times have changed.
"I feel strange about tennis," said Gulbis. "I just quit with my coach before this tournament. Sometimes changes are good. Maybe it even got me a little bit more motivated, more pumped, a little bit more excited. Now I have to prove again something to somebody, to myself.
"At least now I'm in decent shape and in a decent position where I can search for a coach. After a couple of results like this, coaches are also motivated. They see this guy is not a lost cause."
Gulbis next meets sixth seed Jo-Wilfried Tsonga, who looked set to become the biggest casualty of the men's tournament so far when he lost the first two sets against Marcos Baghdatis.
But Tsonga, a semi-finalist in two of the last three years, recovered to win 6-7 (6/8) 3-6 6-3 6-2 6-2.
Thiem, 22, came into the tournament as a dark horse and he set up an enticing third-round clash against 19-year-old German Alexander Zverev, with the winner likely to face Nadal in the last 16.
Another youngster of whom great things are expected is 19-year-old Borna Coric, who knocked out 20th seed Bernard Tomic, while seventh seed Berdych and 12th seed David Goffin also made it through.
Thiem and Tomic are among several leading players to have opted out of the Olympics, preferring to play ATP events instead.
That baffles Nadal, who will carry Spain's flag at the opening ceremony in Rio. He had been due to do so in London but was forced to miss the tournament through injury.
"The Olympics is the most important event in the world of sport," said Nadal.
" If you don't want to be in the most important event in the world of sport, then it is difficult to understand what's the motivation for the rest of the things?"
