Novak Djokovic took a bite of a gluten-free cake in a post-match presentation on Wednesday at the Dubai Tennis Championships after earning the 700th win of his career.
The top seed beat Tunisan Malek Jaziri 6-1, 6-2 in 65 minutes to lead his fellow seeds into the quarter-finals.
The Serb had 25 unforced errors in what could not be called a perfect performance which still carried him to 14-0 this season. Djokovic is the third active player to crack the 700 barrier behind Roger Federer (1,067 wins) and Rafael Nadal with 775.
"I've played a lot of matches and I'm very pleased and very proud of each win I've had," Djokovic said. "I started as a professional just over 10 years ago.
"I love this sport with all of my heart and enjoy every moment of it. I expect a lot from myself, I'm trying to improve and get better in every element of my game.
"But I know I'm not the only one who wants to be number one and win titles."
Second seed Stan Wawrinka needed five match points to finish off 188th-ranked Croatian qualifier Franko Skugor to advance to the last eight for the first time in the emirate.
Other seeds comfortably pounded lightweight opposition, Tomas Berdych beating Italian qualifier Thomas Fabbiano 6-2, 6-2 to next face unpredictable Nick Kyrgios.
Berdych, the third seed and twice a finalist, was untroubled in his match but was already looking ahead of his third clash with Marseille champion Kyrgios since the start of the year.
Unseeded Australian Kyrgios won his second match since arriving in Dubai on Tuesday as he defeated Mikhail Kukushkin 6-3, 6-2 for a seventh win in a row.
"He's full of fireworks on the court - in a good way. He's playing really aggressive. He's going for a lot of shots, risking a lot," Berdych, who beat the 20-year-old Australian in Melbourne last month but lost to him in France four days ago, said.
"For me it's going to be a big challenge. I have a lot of revenge to get back after last week. I must refocus myself, try to raise the game, and play some good tennis again."
Spain's number four Roberto Bautista Agut remained the man to beat in 2016 after notching up his 16th win of the season as he dispatched South Korean teenager Chung Hyeon 6-0, 6-1.
Sixth seed Feliciano Lopez beat Czech Lukas Rosol 6-3, 7-6 (9-7) to next play Djokovic while German Philipp Kohlschreiber, seeded eighth, defeated Croatian teen Borna Coric 6-2, 7-6 (7-5) and will take on Wawrinka.
