Ekaterina Makarova of Russia upset third-ranked Victoria Azarenka 1-6, 6-2, 6-3 Wednesday to reach the third round of the Madrid Open.
Rafael Nadal swept past Benoit Paire 6-3, 6-4, spoiling the Frenchman's 24th birthday.
Azarenka, runner-up in Madrid the past two years, lost her temper, broke her racket and argued with the chair umpire.
The Belarusian double-faulted five times and got in just over half of her first serves. The 24th-ranked Makarova had 60 percent first-serve accuracy.
