"Barbados helped my confidence a lot. Coming here and seeing a bit of grass, I said ‘well, something should be in it for me’ and I went out there and put the ball in the right spot," Lawson told reporters in a post-play press conference.

Lawson, playing in only his 7th Test, took the first three Australian wickets but reserved some of his most venomous deliveries for tail-enders Brett Lee, Stuart MacGill and Jason Gillespie.

"I just tell myself, we are at the tail and I just run in and gave a couple of short balls and it worked out well.

Lawson, 21, whose figures of seven for 78 in 19.1 overs were the best ever by a bowler in 18 Tests at the ARG says he is "feeling good" about the accomplishment but the hard work has only just started.

"I hope the rest of the fellows will go out there and do their best tomorrow (today) so that at the end of the day we can come out victorious," Lara said.

Lawson said he has never entertained any thoughts about a change in his bowling action but credits former West Indies fast bowler Courtney Walsh for helping him and putting him "through the whole process" of fast bowling.

"I worked hard at it and finally I am getting some success," Lawson said.

West Indies captain Brian Lara lauded his four-man bowling attack of Lawson, Mervyn Dillon, Vasbert Drakes and rookie off-spinner Omari Banks for what he called a "good all-round effort".

"I am quite happy to be batting today (yesterday) on a first day of a Test match after bowling out Australia," Lara said.

"Today (yesterday) has been our best and it shows signs of improvement and I must congratulate the boys," Lara remarked.

"Lawson was the pick of the bowlers today but mention must be given to guys like Dillon, who got the breakthrough with the two main wickets in the middle in Steve Waugh and (Adam) Gilchrist.

"Young Banks, who kept the pressure on. Drakes, even though he went wicket-less also kept the pressure on so it was a good all-round effort from everyone," Lara declared.

Despite dismissing Australia for their lowest total of the four-match series so far, the West Indies missed at least half dozen chances and Lara reckons that this is an area they must work harder at.

"We still have a lot of work to do in the field (but) I think things are coming around," added Lara noting that the West Indies cannot rest on their laurels because they have bowled out Australia.

"It is the last Test match. We are not going to be playing any red ball cricket for a while and I think the guys got to realise that, settle down. Even Vasbert Drakes, he's got to go out there and apply himself," Lara noted.

"We've got 240 to overhaul. When we get there, we got to bat on. Four days left in the Test match, we would like to bat for as long as possible.
