NOVAK Djokovic could not hide his satisfaction after completing the first step on the road to a place in history at the Australian Open.
"It was a good performance for a first round," Djokovic said.
"I felt I was in control of the match in the opening two sets. Then, you know, he started playing better, striking the ball quite well from both sides on the baseline. I thought he was serving really precisely and really well.
"It was tough to break. But in the end, that 11th game, I made some good shots, good points and managed to go through in straight sets."
With title challengers Roger Federer and Andy Murray not playing until tomorrow, Djokovic took the opportunity to send a message that he was not willing to give up his crown without a fight.
But although largely satisfied, he admitted there was still room for improvement.
"There are some adjustments that I need to make and get a little bit sharper on the court," he said.
"But it's expected in the first match that you're still not 100 per cent on the court. You're trying to be, but it's going to get better with matches that I play."
Berdych said: "I was able to find my rhythm and did not have to stay on the court that long which is a positive."
With so much focus directed the way of Djokovic, Federer and Murray, Berdych is drifting under the radar. And it is a situation he is quite happy with.
"It's better for me," he added. "Let's leave all the pressure on them. You get so much pressure on the court, you don't need it (off it) as well."
Several other seeds also progressed on day one at Melbourne Park with varying degrees of difficulty.
But 11th seed Juan Monaco could not join them in round two after going down in straight sets to Russia's Andrey Kuznetsov.
Hewitt, making his 17th appearance in this tournament, had his chances, most notably when he established a 3-0 second-set lead having broken twice.
But the Serbian roared back to take the match 7-6 (7/4) 7-5 6-3.
"It's as tough as it gets to play Lleyton here and I am really happy to have won in three sets," Tipsarevic said.
"The first two sets could have gone either way but I felt I had more control in the third."
