The Australian squandered a two-set advantage to lose to Benjamin Becker 2-6, 1-6, 6-3, 6-4, 6-2, in the second round at Melbourne Park.
Questions have been asked for some time regarding how long Hewitt will continue to play on tour, and speaking after losing at his 19th Australian Open, Hewitt was non-committal regarding whether there would be a 20th appearance.
“For some people, I’m sure [twenty is a nice figure to end on]. I don’t know," he said.
"As I’ve said the whole time — I haven’t been kidding anyone — really, I don’t know. I’ve just tried to focus on what I’ve wanted to do, to get the best out of myself (at the Australian Open) this year. I’ll sit back and assess everything after this tournament.”
Hewitt denied that he had taken extra time late in the match to soak in the atmosphere at the Rod Laver Arena.
“Not really,” he said. “You know, it sort of happens that quickly when you walk off. Obviously, a great reception. But you probably don’t take it in as much as you should.
"If you looked at every TV changeover, I’m probably doing exactly the same thing. There was nothing different going through my mind. It was more just trying to work out the situation. I was trying to bust my gut to get the first couple of points. Put some kind of pressure on him. Nothing else entered my mind.
"I’ll sit down and think about it (the future). As I’ve said the whole time, I haven’t thought about anything. But obviously the Davis Cup is the next main thing. Now that we’ve got some guys playing really good tennis at the moment, it’s an exciting time. We have a good chance to possibly pull off an upset. That’s the next focus.”
