Grigor Dimitrov converted his third match point - over 24 hours after he had his first - to beat Jacob Fearnley and reach the Madrid Open quarter-finals.
A day after a nationwide power cut caused chaos in Spain and led to the play being suspended, Bulgaria's Dimitrov beat the 23-year-old Briton 6-4 7-6 (7-3).
The match was suspended on Monday with Dimitrov leading 6-4 5-4 after the electronic line-calling system and scoreboards went down.
Power was restored to the venue on Tuesday morning, with Dimitrov and Fearnley resuming their match after Iga Swiatek's battling three-set win over Diana Shnaider.
