Ben Shelton vs Jakub Mensik — full preview, head-to-head breakdown and prediction for their QUARTERFINAL at the 2026 National Bank Open (ATP Masters 1000 Canadian Open) in Montreal. The defending champion against the Czech who already owns the head-to-head. Two players born in the 2000s, one semifinal spot.
Ben Shelton arrives as the man to beat. The No. 5 seed and World No. 10 is defending the Masters 1000 title he won here last year — his first at this level, beating Karen Khachanov in the final — and he is having the best season of his career: three titles on three different surfaces for the first time, in Dallas, Munich and Stuttgart. He came through windy, awkward conditions to end the run of Brazilian teenager Joao Fonseca 6-3, 7-6(3), staying perfect at this tournament and notching his 30th win of 2026.
Jakub Mensik is the No. 13 seed and World No. 17, 27-13 on the season with a title in Auckland, and he has been quietly clinical all week — past Jacob Fearnley 6-3, 3-6, 6-3, Terence Atmane 7-5, 6-4, and Botic van de Zandschulp 6-4, 7-5. The Miami Open champion has one of the biggest serves on tour and the temperament to match.
Here's the thing Shelton has to deal with: Mensik leads the head-to-head 2-1. Two huge serves, very few return games, and margins measured in a handful of points. Who reaches the semifinals?
