Serena Williams retired because of an injury on Sunday. At 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.
The tournament’s final lasted only 16 minutes.
After the chair umpire announced the retirement, Williams started to cry on her bench. Andreescu went over to comfort her, hugging her and telling Williams how much she admires the 23-time Grand Slam winner.
“I’m not a crier, but, thank you guys,” said Williams as she choked back tears after accepting the second-place check. “I’m sorry I couldn’t do it today. I tried but I just couldn’t do it.”
Williams’ retirement was the last of several high-profile injuries at the Rogers Cup. Fourth-seeded Simona Halep withdrew from her quarterfinal matchup with Marie Bouzkova. On the men’s side, Milos Raonic retired after two sets against Felix Auger-Aliassime in a much-anticipated all-Canadian matchup. No. 16 seed Gael Monfils then withdrew before his semifinal against world No. 1 Rafael Nadal
