Roger Federer won his 17th consecutive match at the Swiss Indoors on Thursday, dispatching Jan-Lennard Struff 6-3, 7-5 to reach the quarter-finals.
The top seed, unbeaten in Basel since 2013, is an eight-time winner of his home event and will next play against either Frenchman Gilles Simon or Latvia’s Ernests Gulbis.
The 37-year-old Federer ranked third in the world, trailed to an early break but soon recovered for 3-all in the opening set.
He then broke for 5-3 before closing out the opener in 27 minutes.
The second set stayed on serve until a fifth double-fault from Struff, which opened the door for Federer to move 6-5 ahead.
Moments later, the 20-time Grand Slam champion served out a 41st victory of the season with a volley into the empty court on his first match point.
Fourth seed Stefanos Tsitsipas dominated Peter Gojowczyk 6-3, 6-1 to line up a quarter-final with one of his toughest NextGen rivals.
The Greek will face Russian Daniil Medvedev, who defeated Italy’s Andreas Seppi 7-6 (7/5), 6-2 in their second-round encounter.
Medvedev owns three titles this season from Sydney, Winston-Salem and last month in Tokyo. He has also defeated last week’s Stockholm champion Tsitsipas in two meetings this season, in Miami and the US Open.
Tsitsipas made his trophy breakthrough at the weekend in Sweden with his first career title.
“I’m playing well,” said 16th-ranked Tsitsipas. “I think the rivalry between the young guys right now maybe even stronger than that of the big names.
“We all want to get to the top sometime, we always want to do better than the other guy.”
Tsitsipas, 20, is the youngest player in the ATP Top 20, and the first Greek to win an ATP title. He also reached his first Masters final in Toronto in August before losing to Rafael Nadal.
Second seed Alexander Zverev ended the run of 174th-ranked Australian teenage qualifier Alexei Popyrin with a 6-4, 6-4 win.
The German next plays Spanish eighth seed Roberto Bautista Agut who continued his quiet progress through the draw, beating Serb Dusan Lajovic 6-7 (6/8), 6-3, 6-3.
