Serena Williams earned her 650th career victory with a 6-2, 6-3 win over Carla Suarez Navarro at the Madrid Masters. Williams, in pursuit of her 60th title, hit 27 winners to her Spanish opponent's five.
"She made me work for every point and it wasn't an easy win," the top-ranked American said. "She just won last week, so she is definitely not an easy player to play."
Williams will next face 2011 champion Petra Kvitova. The fifth-seeded Czech beat Lucie Safarova 6-4, 6-3.
The US Tennis Association also congratulated Williams on the achievement.
Also, Australian Open champion Li Na and Maria Sharapova will meet in the quarterfinals after both won their third round matches.
After a poor opening set, the second-ranked Li overcame a slew of unforced errors and a bothersome toe problem to beat Sloane Stephens of the United States 2-6, 6-3, 6-2.
"After the first set I was like, 'Calm down,'" Li said. "I say, 'OK, I cannot only think about what happened for the game, you have to look forward otherwise you cannot make it.'"
Sharapova beat Samantha Stosur of Australia 6-4, 6-3.
