Andy Murray insists he was not concerned, despite being given an early scare before booking his place in the second round of the Adelaide International.

The 18-year-old had to fight back from a set down before overcoming qualifier Paolo Lorenzi, 24, who was playing his first match at ATP tour level.

The Italian, who had beaten Murray's British compatriot Jamie Delgado in the preliminaries, briefly threatened to spring a surprise before the teenager found his form to claim a 3-6 6-0 6-2 victory.

Murray was just relieved to have successfully negotiated his first match of the year at Memorial Drive.

He said: ''At the start of the year it's just about getting through the first few matches and increasing my match fitness.

"I also want to get my timing back and get used to winning again.

''I think I did that. I didn't panic when I went a set down. I won the second set well and then I got broken and I was two-one down in the third and I came back again.

''So I was happy with the way I fought but I wasn't too happy with the way I played.''

The British number three will face Czech sixth seed Tomas Berdych next and is just one win away from a potential meeting with former world number one and home-town favourite Lleyton Hewitt.

Berdych beat Argentinian Agustin Calleri in three sets, 6-4 6-7 (8-6) 6-4.

He should provide a sterner test for the young Scot, who is making his debut Down Under this week.

Murray has made reaching the top 20 his goal for 2006, and he begins the year ranked 64th by the ATP knowing what is required if he is to achieve that.

''This year the goal is to win the big matches because if I'm going to get into the top 20 then I have to do well at the grand slams and the Masters Series tournaments,'' he said.

His rapid rise last year means he no longer relies on wild cards for admission to tournaments, and he will go straight into the draw for the Australian Open - the year's first grand slam event - this month.
