Wimbledon 2023 champion Carlos Alcaraz passed a tiebreak test on Thursday as the top seed squeezed into the Toronto Masters quarter-finals with a 3-6, 7-6 (7/2), 7-6 (7/3) victory over Hubert Hurkacz.

World number one Alcaraz was only just able to extend his win streak to 14 matches as he fended off a third-set offensive from his 15th-seeded Polish opponent. Alcaraz needed five match points to advance over Hurkacz and flirted with disaster as he let a 5-2 lead in the final set slip into a second consecutive tiebreak.
