Left handers David Warner, Chris Rogers and Usman Khawaja could fill first three batting spots for Australia David Warner could retain his opening spot. DAVID Warner may stay at the top of the order in place of Shane Watson as Australia attempt to get more from their struggling all-rounder. The positive 41 Warner made during the second innings of the third Test at Old Trafford as Australia chased quick runs for a declaration suggested the dashing left-hander was better off taking on the fast bowlers than the spin of Graeme Swann. Coach Darren Lehmann confirmed there was a chance that all three left-handers - Warner, Chris Rogers and Usman Khawaja - could fill the first three places. This would leave the right-handers - Watson, captain Michael Clarke and Steve Smith - to counter Swann, who has a much better record turning the ball across left-handers. That is the order Australia used in their second innings. "The reason we swapped around was for Dave Warner to have a go and Watson to tackle Swann, pretty simple," Lehmann said. We may (promote Warner to open again) but it's the selectors getting together and making that decision. We always consult the captain about what he considers is the best batting order as well, so for us we'll make that decision once we see the wicket in Durham. Lehmann claimed he was in no hurry to have a settled batting order. It has changed significantly in every Test. "We'll certainly look at that option in Australia but at the moment we have to find the best six in the best order, that's what we've got to do," he said. Clarke said Watson had made it clear in the past he wanted to open the batting but that may be changing. "We will continue to talk and assess what is best for the team and Shane understood my reasoning for opening with Warner in the second innings and was more than happy to move to four," Clarke said. And he has made it clear that wherever I want him to bat he will do that for the team. Despite his extensive injury history, Watson has bowled well on this tour without luck. He has delivered 61 overs in total, more than at any stage under Clarke's captaincy since his first series in charge, against Sri Lanka two years ago. Australia may no longer be able to regain the Ashes after the third Test was washed out with England already leading 2-0 but Lehmann denied it was a time to experiment looking ahead to the return Ashes series this summer. "Every Test match for your country is important so we've got to pick the right XI to win the game and have to see how the bowlers pull up obviously from this Test match," said Lehmann. I suppose the weather with the way it happened, they'll be reasonably fresh so we'll just see how they go the next couple of days. This means Jackson Bird may not gain a Test place despite bowling well in lead-up games and being man of the match in his last Test, against Sri Lanka in Sydney during early January. "I still think if it's a Test match you've got to pick your best XI," Lehmann said. If Jackson's in that XI then he's a chance to play. For us you've always got to look ahead I suppose now but for us the most important thing is actually backing that performance up again because our last five days have been outstanding, putting England under pressure. We would have won the Test match quite comfortably (without the rain).
