MIAMI — Canada’s Felix Auger-Aliassime lost 7-6 (5), 7-6 (5) to American John Isner in a third-round match at the Miami Open on Sunday.
Auger-Aliassime, from Montreal, also lost to Isner in two tiebreaks in the semifinals of the Miami Open the last time the ATP Masters 1000 event was held in 2019.
Neither player had a break-point opportunity Sunday with both Auger-Aliassime and Isner winning more than 80 per cent of points when they got their first serve in.
The 11th-seeded Auger-Aliassime lost his third straight tiebreak against the 18th-seeded Isner in the first set on Sunday. The Canadian missed an easy overhead smash on his first service point, giving the hard-serving Isner the advantage he needed to finish it off.
Isner took the final point off Auger-Aliassime’s serve after a long rally to finish off the match.
The six-foot-10 Isner has won all 11 of his tiebreaks in Miami.
Isner won the Miami title in 2018 and was a finalist in 2019.
On the women’s side, eighth-seeded Bianca Andreescu of Mississauga, Ont., was scheduled to face No. 28 seed Amanda Anisimova later Sunday.
No. 6 seed Denis Shapovalov of Richmond Hill, Ont., and No. 12 seed Milos Raonic of Thornhill, Ont., are scheduled to play third-round men’s matches Monday.
