TORONTO (AP) Bianca Andreescu became the first Canadian to win the Rogers Cup in 50 years when Serena Williams retired because of an injury Sunday.
Andreescu was up 3-1 in the first set when Williams called for a medical timeout.
Less than a minute later, the chair umpire announced that the 37-year-old Williams was retiring from the match, handing Andreescu her second WTA Premier title of the season.
