Canada's Eugenie Bouchard upset world No. 2 Angelique Kerber 6-1, 5-7, 7-5 in the second round of the Italian Open in Rome on Wednesday.
Kerber, the defending Australian Open champion, is the highest-ranked opponent Bouchard has ever defeated.
The win was also Bouchard's first against a top-10 player in two seasons.

Bouchard will now face Czech Barbora Strycova, who she has previously defeated three times and lost to only once.
Canada's Milos Raonic was facing Nick Kyrgios in the second round of the men's tournament.

Azarenka out

In other women's action, unseeded Irina-Camelia Begu defeated No. 4 Victoria Azarenka 6-3, 6-2.

Azarenka said she was still affected by a back injury that prompted her to withdraw in Madrid.
"I thought I was okay and was ready to play and came back, so I'm just disappointed," Azarenka said. "It's just unfortunate that I can't play my best tennis."

Federer uses full arsenal

Roger Federer put his full array of shots on display in a 6-3, 7-5 win over Alexander Zverev in the men's second round.
After withdrawing from last week's Madrid Open with lower back pain, Federer looked sharp from the start against the 44th-ranked Zverev, using his backhand slice drop shot especially well.
"I'm happy I was able to play a full match without any setbacks," said Federer, who also missed 10 weeks earlier this year after surgery on his left knee to repair a torn meniscus. "I'm coming off a brutal last few months, and I'm just happy to be able to play normal tennis to some extent. ... So for me it's a big day and huge step in the right direction."
The 19-year-old Zverev, considered a potential future Grand Slam champion, often found himself running down shots wide in the alleys. At one point, the six-foot-six German was pulled so far off the court he ended up in the lap of a line judge — then hugged the official after Federer put away an easy volley.

Djokovic, Murray advance 

Top-ranked Novak Djokovic and Andy Murray also advanced in straight sets on the red clay courts at the Foro Italico.
Djokovic beat 35-year-old French qualifier Stephane Robert 7-5, 7-5 as he seeks a third straight title in Rome and fourth overall.

Robert unleashed a series of winners followed by wild fist pumps as he broke Djokovic's serve early in the second set and when Djokovic eventually broke back, the Serb let out a loud demonstrative scream.
Robert hit more than twice as many winners as Djokovic, 33-16, but also committed far more unforced errors, 32-14.
Murray never dropped his serve, hitting seven aces, as he eliminated Kazakh qualifier Mikhail Kukushkin 6-3, 6-
