Seven-time Grand Slam champion Venus Williams has made an early exit at the Rogers Cup.
The 39-year-old American lost 6-4, 6-2 to Spain’s Carla Suarez Navarro in the first match on centre court at the Aviva Centre on Tuesday.
Suarez Navarro, ranked 26th in the world, snapped a five-match losing streak against the 56th-ranked Williams.
Williams has now lost four matches in a row overall, including a first-rounder at Wimbledon against 15-year-old American Cori Gauff.
Suarez Navarro will face No. 16 seed Anett Kontaveit of Estonia in the second round. Kontaveit beat former world No. 1 Maria Sharapova of Russia in a three-setter on Monday.
Also Tuesday, former world No. 1 Victoria Azarenka of Belarus rolled to a 6-2, 6-2 win over Camila Giorgi of Italy. Azarenka won back-to-back Australian Opens in 2012 and ’13.
