Ashes: Darren Lehmann says David Warner's not the answer to Australia's top-order malaise Ed Cowan is out first ball to a horrible loose shot off the bowling of Steven Finn during day one of the first Ashes Test. DAVID Warner will not be dragged off Australia's A tour of southern Africa to bolster a flaky Australian top order. While debate continues over Ed Cowan's future and where Michael Clarke should bat, Lehmann made it clear that Warner was not the short term answer after missing a month through suspension. "He has to make some runs, it's as simple as that," Lehmann said of Warner as Australia finished the opening day of the first Test at 4-75 in reply to England's 215. Cowan and Clarke both made ducks. "It's really hard to put him into the team when he hadn't played any cricket," Lehmann said of Warner. In the Champions Trophy, although it's a different format, he didn't make any runs there so we've spoken to him about that and he's got to make some runs and get back on tour and see where he goes from there. Warner is likely to fly to Africa on the weekend to play matches for Australia A against a Zimbabwe XI and South Africa A before return to England in time for the third Test at Old Trafford from August 1. "Obviously he's disappointed he's not playing to be perfectly honest," Lehmann said. But he handled it really well and knows what he needs to do. He's been outstanding on the training track but we needed to pick players in form. With 14 wickets falling for 290 runs on the opening day, many batsmen played too expansively for the conditions, with the ball swinging all day under cloudy skies. "Both batting sides would be a bit disappointed on that wicket," Lehmann said. Lehmann claimed that Cowan, who made a first ball duck playing a loose drive, had been ill. He's a bit crook. It's a tummy bug but hopefully it didn't affect his shot selection on that one ball," said Lehmann, who insisted the top three had to support Clarke now he has moved up to number four. "He wants to bat four and I support that," Lehmann said. I like the captain batting at four. The openers have to bat longer than they did today.
