Ana Ivanovic is seeking a different approach after being a shock first-round casualty at the Australian Open.
Ousted fifth seed Ana Ivanovic claimed she was not feeling herself after being beaten by qualifier Lucie Hradecka at the Australian Open.
The Serbian appeared relaxed in her news conference despite suffering a stunning exit at the hands of doubles specialist Hradecka, who pulled off a 1-6 6-3 6-2 victory on Rod Laver Arena.
It was Hradecka's seventh main-draw singles win in her 21st major appearance, but despite the calamitous defeat, Ivanovic gave a smile when detailing the result was the "worst thing".
"I think the whole match I didn't really feel like myself out there. It was really tough for me to find rhythm a little bit. In the third set really felt like she raised her level," she said.
Ivanovic added: "It's really disappointing. You know, it's probably the worst thing [that] could happen.
"But still, the year is young and I really have to now sit and work on a few things and just maybe try to have a different approach to this kind of event and try to see what was lacking."
Ivanovic, who could slip in the rankings after failing to defend her quarter-final points from 2014, rued her lack of killer instinct early in the second set.
The 2008 finalist won the first set in 21 minutes, but Hradecka would open up a 3-0 lead in the second set - and despite Ivanovic levelling at 3-3 - another hot run from the world number 142 squared the match.
"I think actually the important one was beginning of the second set when I had two break points and I had [an] easy miss," Ivanovic said.
"Then she played some good shots to save that game. Then she went on to break me and then got 3-0 up. Obviously that [seventh] game as well played a big part in that second set."
Ivanovic refused to single out her serve - which produced 10 double-faults - as the key to her surprise defeat.
"It was really I think all around the game. That made a big difference. I really felt like I couldn't really put so much power on my serve or the groundstrokes," she said.
"So many times my forehand was finishing short as well and that was very disappointing. In Brisbane my serve was on such a good level. I really felt like I improved in the off-season.
"Obviously today [it] was really not working. I really feel it's just going to probably come back with the next match."
