Bouchard extends career with first-round win at Canadian Open, Carreno Busta prevails in opener

Hometown hero Eugenie Bouchard beat Emiliana Arango 6-4 2-6 6-2 in the first round of the Canadian Open in Montreal on Monday, a win that delayed the former world number five's retirement.

Bouchard announced earlier this month she would walk away from the sport after the tournament but added a condition to that plan in the wake of her thrilling victory in front of a packed crowd.

"If I win this tournament, I will not retire," she said in an on-court interview.

Playing in only her second singles match of the year, Bouchard blasted a forehand winner to take the first set but Colombian Arango turned the tables in the second set amid a cascade of unforced errors from her opponent.

However, Bouchard broke for a 3-1 lead in the decider and hammered a swinging volley to extend the advantage to 4-1.

The 31-year-old wildcard put her hands on her head and then her heart after securing the victory to set up a second round meeting with 17th seed Belinda Bencic of Switzerland.

Briton Emma Raducanu beat her good friend Elena-Gabriela Ruse of Romania 6-2 6-4 and will next meet 32nd seed Peyton Stearns.

"It's very difficult to play someone who you are close to," Raducanu said. "I'm really glad about how I was able to put that to one side for the match and back up a good week in D.C."
