Bouchard defeated Sharapova for the first time by taking advantage of the Russian's 49 unforced errors and struggles on serve, including nine double faults. The 60th-ranked Canadian had 21 break opportunities, converting five of them.

The Madrid Open is only the second tournament for Sharapova since serving a 15-month suspension. The five-time Grand Slam champion reached the Stuttgart semifinals last month. She received a wild card there, and a wild card here. Most players were against her receiving free entry without having to qualify.

Bouchard had not backed off her comments, and said she was looking forward to playing Sharapova, the 2014 Madrid champion.

"It definitely helps when you can back it up," Bouchard said. "Obviously, there was a lot going on besides tennis in this match. As soon as I stepped on the court, I really just wanted to make it about tennis. We both did that. We just battled our hearts out."Sharapova said she didn't need extra motivation to play against anybody.

"I'm just one of the two players out on the court," Sharapova said. "Everything that surrounds myself, I don't pay attention to much of it. I've been part of this game for many years. I know what the drill is."There were a few long stares and some loud cheers by the players after some points.
