MELBOURNE, Australia -- Soaked with sweat and clinging desperately for survival, Maria Sharapova was serving for the match when Australian Open organizers finally decided that the searing heat was extreme enough to suspend matches.
That was 5-4 in the third set, 2 hours and 38 minutes into her second-round match against No. 44-ranked Karin Knapp on Thursday (Australia time). Fifty minutes later, Sharapova converted her fourth match point to clinch her spot in the third round with a grueling 6-3, 4-6, 10-8 victory.
It was 39C (102F) when Sharapova's match started and almost 43C (109 F) by the time she finished, 3:28 later. That was just shy of the maximum forecast during the third straight day of a heat wave in sweltering Melbourne.
Sharapova wasted three match points on serve in the 10th game set, and then had to save break points and serve to stay in the match. She earned a crucial break seven games later, but it was a simple matter of serving out in those brutal conditions.
Three double-faults in the last game -- Sharapova's 10th, 11th and 12th of the match -- gave Knapp another break point and a chance to extend it further. But with a reflex backhand that just caught the line, and two errors from Knapp, it was over.
"I wanted this match. I didn't play my best tennis; I didn't do many things well," she said. "I got through it, and sometimes that's what's important.
"When you win match point you get off the court, no matter how you feel and how tough it was, I really ... I love these moments. "
Sharapova, playing her second tournament back from extended time off for a right shoulder injury, wore ice vests in every changeover after the third game, draped ice bags over shoulders and poured water over her head.
She hit 34 winners but made 67 unforced errors in an increasingly frustrated push to finish points early.
Sharapova recalled a first-round match in sauna-like conditions in Australia in 2007, when she beat Camille Pin 9-7 in the third set.
"I remember being really close to passing out," said Sharapova, adding that her fitness was better now. "I'm feeling much better."
She'll next meet No. 25 Alize Cornet of France, who sobbed after beating Camila Giorgi of Italy 6-3, 4-6, 6-4 in 2 1/2 hours.
"I went really further than my limits. It was really hot, that's why I'm so emotional," Cornet said of the conditions. "Doing something physical in this heat it's just unbelievable."
No. 29 Anastasia Pavlyuchenkova had a 6-2, 6-2 win over Mandy Minella in 1:17 but said her two first-round matches had taken a toll. She said she'd almost passed out in her first-round match.
No. 10 Caroline Wozniacki beat Christina McHale of the United States in three sets in a match played under the roof.
