The 32-year-old Spaniard will face fifth seed Juan Martin del Potro in Friday’s semi-final.

The Argentine overcame third seed Marin Cilic 7-6 (7-5) 5-7 6-3 7-5 in another quarter-final that was moved to Thursday.

The winner of the contest will face either Austrian seventh seed Dominic Thiem or unseeded Italian Marco Cecchinato in Sunday’s final.
