Key takeaways

  • Ben Shelton and Joao Fonseca will meet in a Munich quarterfinal rematch during the Montreal round of 16.
  • The 2026 Canadian Open marks a 19-year milestone with four under-21 players reaching the fourth round in consecutive Masters 1000 events.
  • Ben Shelton remains the only top 10 seed left in the Montreal draw as he seeks to defend his title.

What Happened

Defending champion Ben Shelton will face 19-year-old Joao Fonseca in the round of 16 at the National Bank Open in Montreal. Shelton, the only top 10 player remaining in the draw, advanced to the fourth round without dropping a set, extending his winning streak at the Canadian Open to eight matches. Fonseca secured his place by defeating ninth seed Casper Ruud 7-6(6), 6-3, following an earlier victory over Stefanos Tsitsipas.

This match serves as a rematch of the Munich quarterfinals from earlier this year, where Shelton defeated Fonseca in three sets. In that previous encounter, Shelton utilized his serve effectively, hitting seven aces and winning 38 of 45 first-serve points.

Background

The 2026 Canadian Open has become a milestone for younger players on the ATP Tour. For the first time since 2007, four players under the age of 21—Joao Fonseca, Rafael Jodar, Jakub Mensik, and Learner Tien—have reached the fourth round at two consecutive ATP Masters 1000 tournaments. This repeat performance follows the Italian Open, matching a feat last achieved by Novak Djokovic, Rafael Nadal, Andy Murray, and Richard Gasquet during the 2007 Indian Wells and Miami Open events.
