Overview
- Denis Shapovalov retired in the third set of his opening match on Tuesday after an ankle problem that he says began in last week’s Los Cabos final left him with limited movement.
- Montreal’s Gabriel Diallo also withdrew on Tuesday with a left‑leg issue, visibly emotional as he left the court during his second‑round match.
- Félix Auger‑Aliassime pulled out before his scheduled match on Wednesday after suffering a back injury during practice, and his slot was filled by a lucky loser.
- With those exits, no Canadian men remain in the National Bank Open singles draw and several opponents advanced or received walkovers, reshaping the tournament schedule.
- Players and coaches have pointed to tight scheduling and travel as causes and Shapovalov said he may skip upcoming events such as Cincinnati to prioritise recovery, a sign of broader player‑management trade‑offs on the tour.
