Aussies delay naming Test side for Perth Ashes Test Cricket's man of the moment Mitchell Johnson says Aussie fast bowlers are excited to use the WACA's wicket to their advantage in the third Ashes test. Paceman Ryan Harris bowls during an Australian nets session at the WACA ground today. James Faulkner receives attention after being hit on the hand while batting during a net session. MICHAEL Clarke has delayed naming his starting XI for the third Ashes Test, to give paceman Ryan Harris time to prove his fitness and to await medical scans on James Faulkner's injured hand. Australia can regain the Ashes with a win in the third Test, starting tomorrow at the WACA, where conditions are ideal for Harris and pace spearhead Mitchell Johnson. "Ryan bowled today so we're going to have to wait and see how he pulls up," Clarke said. I'm confident he'll be fine. Faulkner's already slim chances of playing were further reduced when he was sent for scans after being struck a nasty blow on the hand during net practice at the WACA ground this morning. Faulkner, who was 12th man for the Brisbane and Adelaide Tests wrung his right hand in pain after being hit by a net bowler and immediately walked off to receive treatment. Australian captain Michael Clarke was unable to provide a fitness report on him. "It looked like a bit of a nasty hit and hopefully there's no break," Clarke said. Harris bowled at full pace in the nets today and didn't appear to be troubled by the knee soreness. "I'm going to wait until the toss and see how everybody pulls up after training and it gives us another opportunity to have a look at the wicket," Clarke said. Harris has struggled with injuries throughout his career, limiting him to 18 Tests, but he has become a key member of Australia's pace attack and was the leading bowler on a losing team in the last Ashes series. A delay in naming the Test team will allow Australia to make a final assessment of a wicket not showing quite so much of a greenish tinge today. Although the temptation would be to unleash Johnson at the shell-shocked Englishmen right from the start, Clarke admitted he always found it hard to send the opposition in, unless the wicket was an absolute greentop. The Perth Test will be Clarke's 100th, and he is hoping to celebrate the milestone by taking an unassailable lead in the five-test Ashes series. That's why it's most special for me. The fact that we have a chance to win the Ashes," he said. It's fantastic that I've been able to play 99 test matches for my country. Johnson has taken 17 wickets in the first two tests and is expected to trouble the English batsmen again on a pitch renowned for its pace and bounce. Clarke spent time yesterday watching the two standby pacemen, Doug Bollinger and Nathan Coulter-Nile, bowl in the nets. But all indications are the selectors are leaning towards retaining off spinner Nathan Lyon, and Faulkner's mishap will surely strengthen Lyon's chances of playing.
