Ash Barty has joined Daria Gavrilova in the last 32 of the WTA Rogers Cup in Toronto after Oceane Dodin retired hurt in their first-round match
The Australian world No.57 was leading 5-0 after just 22 minutes when her 20-year-old opponent pulled the pin.
Barty, who came through qualifying to reach the tournament, will now face 16th-seeded Russian Elena Vesnina in the second round.
Vesnina beat America’s Alison Riske 6-3 6-3.
Dodin, ranked 47th in the world, reached the semifinals of the Citi Open in Washington last week, losing to eventual winner Ekaterina Makarova.
Barty joins fellow Aussie Daria Gavrilova in the second round; Gavrilova next faces Barbora Strycova.
