Leylah Fernandez ousted in Miami Open 3rd round by world No. 5 Jessica Pegula

Canada's Leylah Fernandez fell 7-5, 6-4 to Jessica Pegula of the United States in third-round action at the Miami Open on Sunday.

The Laval, Que., native committed four double faults, won 58.6 per cent of her first-serve points and broke on three of her nine opportunities. Each player had one ace.

Pegula, ranked fifth in the world, only had one double fault and won 70.5 per cent of her first-serve points, while breaking on five of her 13 chances.

She has reached the Miami Open semifinals for the last two years.

The 35th-ranked Fernandez advanced after a 6-4, 6-2 second-round win over Colombia's Emiliana Arango on Saturday.

In women's doubles action, Ottawa's Gabriela Dabrowski and New Zealand's Erin Routliffe defeated Japan's Miyu Kato and Indonesia's Aldila Sutjiadi 6-4, 6-4 in second-round play.

On the men's side, Denis Shapovalov of Richmond Hill, Ont., will face Italy's Matteo Arnaldi in a third-round match later Sunday.

Third-ranked Coco Gauff came from behind in the first set to beat Oceane Dodin 6-4, 6-0 and advance to the fourth round for the second time in her career.

Gauff won 10 straight games after Dodin took a 4-2 lead in the opening set, thanks partly to nine double-faults by Dodin at critical moments.

Gauff has just one loss in her past 23 matches in the United States. That defeat came against Maria Sakkari at Indian Wells earlier this month.

Gauff, who turned 20 on March 13, is the youngest American player to hold a top three seed at Miami. The reigning U.S. Open champion, who is from South Florida, attended the event growing up and said capturing a title there would be special.

"It would be really cool to win here at home," said Gauff, who
