Wesley Koolhof and Neal Skupski reached the Roland Garros quarter-finals as a team for the second consecutive year Saturday when they defeated Aleksandr Nedovyesov and Miguel Angel Reyes-Varela 7-5, 6-4.
Koolhof and Skupski won 86 per cent (31/36) of their first-serve points and broke three times to advance after one hour and 29 minutes.
The top seeds won seven tour-level titles last season but have yet to triumph this year. Chasing their first major trophy in Paris, the Dutch-British tandem will next meet 10th seeds Marcel Granollers and Horacio Zeballos or Marcelo Melo and John Peers.
Defending champions Marcelo Arevalo and Jean-Julien Rojer also advanced, overcoming Jamie Murray and Michael Venus 6-2, 6-2. Murray and Venus clinched the crown in Geneva last week but were unable to topple the third seeds.
Arevalo and Rojer are aiming to clinch their third tour-level title of the season this week, having won in Adelaide and Delray Beach. They will next play Lloyd Glasspool and Harri Heliovaara or Matwe Middelkoop and Andreas Mies.
