Denis Shapovalov of Richmond Hill, Ont., saw his Madrid Open run end in the third round Tuesday with a 6-3, 7-6 (3) loss to Australia’s Alex de Minaur.
Shapovalov fired six aces but was undone by five double faults and won just 14 points on return.
Their match had been postponed from Monday after a mass power outage disrupted large parts of Spain and Portugal.
De Minaur will face the winner of No. 17 Stefanos Tsitsipas and No. 10 Lorenzo Musetti in the fourth round of the clay-court tennis event.
Montreal’s Gabriel Diallo, the last Canadian standing in Madrid, plays Britain’s Cameron Norrie later Tuesday.
Power was restored at the Caja Magica tennis complex Tuesday and the tournament resumed with a packed schedule that included second-ranked Iga Swiatek advancing to the quarterfinals.
Swiatek defeated Diana Shnaider 6-0, 6-7 (3), 6-4 to stay on track to defend her title in the Spanish capital.
After a major blackout that prompted 22 matches to be postponed on Monday, most parts of Madrid regained power overnight. But the Caja Magica was still without electricity early Tuesday, causing a delay in the opening of the gates for fans.
However, the power came back quickly, and organizers did not have to alter the day’s schedule of matches, although there was the possibility of the night session being delayed because of the high number of matches during the day.
In one of the first matches of the day, Swiatek cruised in the first set but had to save 11 of 13 break points to seal a hard-fought victory against the 13th-seeded Shnaider.
Swiatek has not lost before the quarterfinals in seven tournaments this season but hasn’t gone past the semifinals since Roland Garros last year. She will next face Keys, who comfortably defeated Donna Vekic 6-2, 6-3.
It will be Swiatek’s first meeting with Keys since she lost despite having match point in the semifinals of the Australian Open.
