MELBOURNE, Australia — Maria Sharapova survived the searing heat and an intense challenge from Karin Knapp to advance to the third round of the Australian Open with a grueling 6-3, 4-6, 10-8 win in 3 hours 28 minutes.
The temperature was forecast to spike at 111 Fahrenheit Thursday, on the third straight day of a heat wave. It was already 102 when Sharapova's match started and increased to 108.5, forcing organizers to enact the tournament's extreme heat policy and suspend matches on outside courts.
Sharapova wasted three match points on serve at 5-4 in the third set, and then had to save break points and serve to stay in the match before getting the crucial break in the 17th game of the deciding set.
Despite serving three double-faults in the last game, the third-seeded Sharapova held on to win on her fourth match point 50 minutes later when Knapp made consecutive errors at deuce.
"It's tough for both of us. We fought as hard as we could," Sharapova said. "She played some of the best tennis I've seen her play."
Sharapova, playing her second tournament back from extended time off for a right shoulder injury, wore ice vests during every changeover after the third game, draped ice bags over her shoulders and poured water over her head.
She recalled a first-round match in sauna-like conditions in Australia in 2007 that she won 9-7 in the third set against Camille Pin and in which, she said, "I remember being really close to passing out."
"I'm feeling much better now," she said.
She'll next meet No. 25 Alize Cornet of France, who sobbed on court after coming back to beat Camila Giorgi of Italy, 6-3, 4-6, 6-4 in 21/2 hours.
"I think I spent enough time on this court for today," Cornet said in her on-court interview. "I went really further than my limits. It was really hot, that's why I'm so emotional."
"Doing something physical in this heat, it's just unbelievable."
No. 29 Anastasia Pavlyuchenkova also complained about the heat after her 6-2, 6-2 win over Mandy Minella.
Pavlyuchenkova finished in 1 hour 17 minutes, but said it still took a toll. She said she nearly passed out on court in her first-round match.
"It's really tough to play your best," she said. "When you get a little bit of heat stroke your body feels really heavy.
"My body was really hot, you feel sluggish, and you get frustrated because you can't play your good tennis."
In other results, No. 20 Dominika Cibulkova beat Switzerland's Stefanie Voegele, 6-0, 6-1, Ukraine's Elina Svitolina had a 6-4, 7-5 win over Australian wild-card entry Olivia Rogowska and Kazakhstan qualifier Zarina Diyas beat New Zealand's Marina Erakovic 6-4, 6-0.
In the only men's match completed before the extreme heat policy was invoked, No. 16 Kei Nishikori got a 6-1, 6-1, 7-6 (3) victory over Dusan Lajovic.
