Serena Williams upset by unseeded Makarova in Melbourne

(CNN) -- Unseeded Russian Ekaterina Makarova upset five-time champion Serena Williams of the United States 6-2 6-3 on Monday to reach the quarterfinals of the Australian Open.

The fourth-round match was played as temperatures hit above 32 degrees Celsius (90 degrees Fahrenheit).

Makarova's two previous grand slam appearances -- at Wimbledon and the U.S. Open last year -- ended with losses in the first round as she faded from a career-high 29th in the rankings -- a position she reached with last-16 appearances in Melbourne and at the French Open.

"I'm surprised because she's a great player and it's really tough to play against her," said the 23-year-old Makarova, who will next play her fourth-seeded compatriot Maria Sharapova.
