It was a day of unexpected absences at the Rogers Cup on Tuesday. Andrea Petkovic failed to make her match, Svetlana Kuznetsova pulled out injured, the power went out, and so too did an inconsistent Eugenie Bouchard.
Amid the surprising run of events, there were some predictable outcomes. Third-seeded Agnieszka Radwanska won through to the second round with a 7-5, 7-5 win over Barbara Zahlavova Strycova, while Ana Ivanovic and Carolina Wozniacki both breezed through.
Ivanovic beat Timea Bacsinszky 6-1, 6-2 while Wozniacki was much too good for veteran Daniel Hantuchova, winning 6-1, 6-1.
Radwanska's next opponent will be Madison Keys, who progressed when Kuznetsova retired when trailing 6-1, 3-2.
Ivanovic will next face Coco Vanderweghe, who beat Shuai Zhang 6-2, 6-4 while Wozniacki will meet Klara Koukalova.
The main upset of the day was the elimination of local favorite Bouchard by young American Shelby Rogers, 6-0, 2-6, 6-0 in a second-round match.
"It was cool to see the support she has here and it's fun to see that much support for tennis," Rogers said. "I knew what I was getting into so I was prepared for it. I hope that doesn't happen too often, but I know she's a mega superstar up here."
Bouchard, who had not played since reaching the Wimbledon final last month, was clearly out of touch, holding serve only twice in the match.
"I was feeling the pressure on the court and I was feeling kind of match rusty," Bouchard said. "I knew it would be kind of a difficult situation, but I'm happy I was able to turn things around and not let it get away completely."
Rogers, who has beaten Bouchard both times they have played, will face the winner of the Wozniacki-Koukalova match.
Petkovic pulled out with a viral infection, and her place was taken in the draw by lucky loser Elena Vesnina, who beat Camila Giorgi 6-4, 1-6, 6-1. Vesnina is in the same eighth of the draw as second seed Elena Vesnina, who had a first-round bye and will being her tournament on Wednesday against Casey Dellacqua.
One of the main talking points of the day was the power failure throughout the facility, which made life difficult on court and off.
Play went on despite the lack of electricity, which shut down scoreboards and umpires' microphones.
"In the locker room, it's so dark," Wozniacki said. "We have to use our flashlights and phones. The water is freezing, as well."
Venus Williams rebounded from a shaky second set to defeat Anastasia Pavlyuchenkova 6-1, 3-6, 6-2.
Williams was on court in the early afternoon when the power went off.
"It was like going back to the southern California juniors," she said. "But I tried to think of it as positive, like 'this will be just like practice, so go ahead and relax. It will be a practice match.' You try to play those mind games when you're out there."
Williams is on the same side of the draw as her sister, top-seeded Serena, who begins play Wednesday. They could not meet before the semifinals.
Serena Williams is to face Samantha Stosur, who beat qualifier Monica Puig 6-2, 6-2.
"I would love if we both got to the semifinals," Venus said. "I fell a little short last week (at Stanford), but that's why I'm playing these matches this summer. I'm getting better rhythm as I go."
Among other matches, 14th seed Carla Suarez Navarro defeated Bojana Jovanovski 6-4, 6-3.
