Ben Shelton’s Montreal title defence sharpened: a 6-3, 6-2 win over Zizou Bergs in just over an hour put him in the round of 16. Tallon Griekspoor backed up the Zverev upset by beating Matteo Arnaldi 3-6, 6-4, 6-3.

Shelton: eight aces, no sets dropped
The fifth seed broke for 4-2, posted three love holds in the second set and still has not dropped a set this week. With every higher seed gone, Shelton is the clearest remaining favourite. Next: Ruud or Fonseca.
Griekspoor’s run continues
A medical timeout for his back after set one did not stop the Dutchman. He took the next two sets and reached a Masters R16 for the fifth time — first this season. Daniel Merida awaits after beating Michelsen.

How to read the draw
First-serve %, break points saved and second-serve return quality. Zverev context: upset report; feed /tennis.
Shelton’s second-serve stability in tiebreaks is the hidden skill of the week. Griekspoor must show his back survives a third straight hard-court match. An open draw raises the price of calm mid-seeds before Cincinnati.
