Big-serving American Ben Shelton has brought Alex de Minaur's hard-court winning streak to a shuddering halt, cruising to a straight-sets victory in their Canadian Open quarter-final.
Shelton won the first clash between the pair, beating the Australian ninth seed 6-3 6-4 in Toronto on Tuesday (Wednesday AEST).
The fourth-seeded American left-hander was pretty much invulnerable on serve, rocketing down 11 aces to just one from de Minaur.
