Victoria Azarenka lost her temper, broke her racket and argued with the chair umpire in an exit Wednesday from the Madrid Open, where she's been runner-up the past two years.
Losing to Ekaterina Makarova of Russia 1-6, 6-2, 6-3 in the second round ended Azarenka's 18-match winning streak to start the season.
Meanwhile, Rafael Nadal spoiled Benoit Paire's 24th birthday by sweeping past the Frenchman 6-3, 6-4. The fifth-ranked Nadal's hopes of returning to the top four in time for the French Open were boosted by Novak Djokovic's loss on Tuesday.
Azarenka returned after a two-month layoff because of an ankle injury. She double-faulted five times and got in just over half of her first serves. The 24th-ranked Makarova had 60 percent first-serve accuracy.
The Belarusian berated Alves after picking up a second code violation for smashing her racket in the third set.
''After all you've done, how are you still in the game?'' Azarenka shouted at the official while on court.
