Medvedev and Rublev advance to Dubai semifinals. Humbert saves 3 match points to beat Hurkacz

DUBAI, United Arab Emirates (AP) — Daniil Medvedev and Andrey Rublev stayed on course toward a potential rematch for the title at the Dubai Championships after the Russians won their quarterfinals Thursday.

Medvedev, the defending champion and No. 1 seed, defeated eighth-seeded Alejandro Davidovich Fokina 6-2, 6-3 to set up a semifinal against fifth-seeded Ugo Humbert.

The second-seeded Rublev advanced when Sebastian Korda retired with an unspecified injury. Rublev was up 6-4, 4-3 at the time.

Rublev will face seventh-seeded Alexander Bublik, who reached the last four after his Czech opponent Jiri Lehecka also retired with an injury. The big-serving Bublik was leading 6-4, 4-1.
