West Indies captain Darren Sammy and his opposite number Michael Clarke are confident that their injury-hit fast pace attacks will be up to the task come next week's third Test.

Having seen the rain-hit second Test end in a draw on Thursday, attentions have immediately switched to the final encounter in Dominica.

The Australians have lost both Peter Siddle and James Pattinson to injury, with the duo returning home, leaving Ben Hilfenhaus, Ryan Harris and Mitchell Starc as the only remaining fast bowlers in the Caribbean.

While the loss of the experienced Siddle and the dynamic Pattinson is certainly a blow, Clarke is confident that Starc will step up to the plate.

"It's obviously disappointing that we lose two very good bowlers, but Mitchell Starc certainly comes into contention now as one of our fast bowlers, or we have to option to play two spinners again,'' said Clarke.

"I thought (Starc) bowled really well throughout the Australian summer, he's bowling very well in the nets - I've seen that first hand - and I think if he gets an opportunity he'll grab it with both hands.''

The West Indies have worries of their own when it comes to the pace department.

Fidel Edwards is struggling with a back injury and his obvious replacement, Ravi Rampaul, is still making his way back to full fitness after recovering from dengue fever and a shoulder problem.

However, Sammy is not particularly concerned.

"So far we've been using the same combination and it's worked for us," said Sammy. "Fidel has a slight pain in his back so we'll monitor that. If not then Ravi comes in and I know Ravi will do the job for us."

Edwards was luckless for much of the second Test while Kemar Roach created all sorts of problems for the Australians, a fact that hasn't gone unnoticed.

"It's not only this series, it's been the last year and a half, there's been a massive improvement in the bowling department," added the captain.

"We can get 20 wickets in Test matches and we bowl out teams ... that was something we were not doing in the past. So definitely the bowling has improved, especially under coach [Ottis] Gibson and it will continue.

"To have a guy like Ravi Rampaul, who took so many wickets for last year on the bench shows we have depth. Kemar has been very good against the Australians and Fidel has been bowling well, without any luck, and I know Ravi is eager for his opportunity."

The second Test could so easily have turned out differently had the rain stayed away on the final day.

Clarke declared early in the afternoon with his side on 160 for eight, setting the hosts a victory target of 251 in 61 overs.

The Windies were reduced to 53 for two off 11 overs before the rain returned to end proceedings once and for all.

For the second Test in a row Clarke made an aggressive declaration and while it could have back-fired, Clarke has no intention of changing his tactics.

"My goal my whole career has been to help the Australian team win as many games as possible and I guess now that I am captain I have the opportunity to show that," said the 30-year-old.

"At times with my declaration, when there is a chance for winning, you've got to have a go at it.

"There's going to be times that it might backfire and we might lose every now and then. But I enjoy the brand of cricket that we're playing at the moment.

"I know the guys are really focused on the team having success and trying to win as many games as we can. And I think it's bringing the best out of the team."

For his part, Sammy believes that his side could have chased down the total and that they are confident they can level the series.

"Sixty overs was enough. We thought we could get the runs. Our plan was to see how far we could get by tea and then reassess after that," he said.

"The guys believe now that we can not only compete but we can win matches against top opposition and we go into every game thinking we can."
