Russian star Maria Sharapova said Thursday her intense training after shoulder surgery had paid off after surviving a big scare against Karin Knapp in intense heat at the Australian Open.
The third seed battled through temperatures of up to 42 Celsius (107.6 Fahrenheit) and a third set lasting nearly two hours to overcome the 44th-ranked Italian 6-3, 4-6, 10-8 to make the third round.
The four-time Grand Slam champion was forced to stay on court for three hours 28 minutes as she seeks her first major title since the French Open in 2012.
The conditions were so tough that organisers suspended play at the tournament midway through the third set. However, under tournament rules, Sharapova and Knapp had to finish the set before coming off.
“I’m really happy to get through, I really am,” she said.
“I worked really hard in the last few months and I wanted this match. I didn’t play my best tennis; I didn’t do many things well. But I got through it, and sometimes that’s what’s important.”
Now under coach Sven Groeneveld after a failed, one-tournament partnership with Jimmy Connors, the 26-year-old is coming back from surgery, and she struggled against Knapp.
Her serve let her down and she only converted seven of 20 break points.
Sharapova admitted she went through the whole gamut of emotions.
“You have so many mixed emotions because you have opportunities and chances, and then you’re down and then you feel you’re out. So you’re going through all of this within these three hours or more,” she said.
“I went through all the different ones, like, ‘How could you miss those second-serve returns? Why are you going for so much?’ The other side of my brain, ‘Well, it’s 110 degrees. Of course you’re going for too much.
“When you win match point you get off the court, no matter how you feel and how tough it was, I love these moments. That’s why I play the sport,” she added.
Sharapova got the match at Rod Laver Arena underway by holding serve and Knapp did the same as the two players got the measure of their games.
The Russian struggled with her serve in the first round and it again posed a problem, with three double faults in the third game allowing Knapp to get an unexpected break.
But the Italian failed to make the most if it, losing her next service game to love as Sharapova’s probing baseline shots started finding their mark.
The Russian, at her 11th Australian Open, which she won in 2008, held serve to go 3-2 in front and began applying the pressure, finally getting another break.
She held as Knapp started wilting in the oven-like conditions and she served out the set before donning an ice vest and gulping water at the changeover as she desperately tried to cool down.
Knapp didn’t give up and bounced back in a close-fought second set, making the most of too many Sharapova errors to level the match.
The heat rule was in effect, giving them a 10-minute break between the second and third sets, and Sharapova returned refreshed.
The pair traded breaks before Sharapova had three match points in the 10th only to throw them away. With Knapp then holding serve, Sharapova had to serve twice to stay in the match before breaking in the 17th and serving out for victory.
Sharapova, who returned from injury at the Brisbane International this month, next plays French 25th seed Alize Cornet.
World No 5 Agnieszka Radwanska booked her place in the third round with a straight-sets victory over Belarussian Olga Govortsova 6-0, 7-5. She’ll be matched up with Russian 29th seed Anastasia Pavlyuchenkova, who beat Luxembourg’s Mandy Minella 6-2, 6-2.
Tenth-seeded Caroline Wozniacki lost the second set to Christina McHale but moved on with a 6-0, 1-6, 6-2 victory. Spain’s Garbine Muguruza awaits in the third round.
Earlier Romanian 11th seed Simona Halep dropped her first set to American Varvara Lepchenko but rebounded to win 4-6, 6-0, 6-1. She’ll face Kazakh qualifier Zarina Diyas, who dispatched New Zealand’s Marina Erakovic 6-4,6-0. And 16th seed Carla Suarez Navarro will meet 20th seed Dominika Cibulkova in the third round after both beat their second-round challengers.
Later, second-seeded Victoria Azarenka faces Czech Barbora Zahlavova-Strycova and 13th seeded American 20-year-old Sloane Stephens matches up with Croatian Ajla Tomljanovic. No 8 seed Jelena Jankovic and 32nd seeded Magdalena Rybarikova are also still scheduled to play on Thursday.
