Siddle, Khawaja left out of warm-up match James Pattinson and Peter Siddle during a nets session in Worcester on Monday. The Ashes selection plot thickened on Monday when fringe batsman Usman Khawaja and fast bowler Peter Siddle were left out of Australia's final warm-up match before the first Test. Australia named a deep batting line-up with Ed Cowan and Chris Rogers joining Shane Watson at the top of the order. Spare batsman Steve Smith is likely to bat at six but that spot could be taken by David Warner when he returns from suspension. Khawaja, who has hovered on the outskirts of the team since December without playing a Test, made 27 and 73 against in the first tour match against Somerset. Phillip Hughes has a significant advantage over his former NSW teammate, given another chance to bat against his old county, Worcestershire, after making half centuries in both innings at Taunton. Siddle was off the pace in Taunton, lacking his usual, relentless grunt and returning match figures of 1-117, but will be rested along with the likely new ball Test pair, Mitchell Starc and James Pattinson, for the Worcester game. The Victorian quick has been the most dependable member of the Australian attack for the past two years, and it was unclear when the team was named on Monday what the decision meant for his prospects of selection for the first Test starting on July 10 at Trent Bridge. Ryan Harris, who has an exceptional Test record but a disjointed career because of injuries, will be able to stake a claim for a Test spot during the four-day game which begins in Worcester on Tuesday. Nathan Lyon will be rested to give teen spinner Ashton Agar (who is not an official member of the squad) a chance to impress. The selectors on tour, Rod Marsh and coach Darren Lehmann, chose to have another look at bowling allrounder James Faulkner, who took a wicket in each innings at Somerset but had limited chances to bat, with his unbeaten 22 halted by the first innings declaration. He made five not out in the second innings. Lehmann has said Faulkner needs to make runs to command a spot at No.7. Australian team for first-class match v Worcester: Shane Watson, Ed Cowan, Chris Rogers, Michael Clarke (c), Phillip Hughes, Steve Smith, Brad Haddin, James Faulkner, Ryan Harris, Ashton Agar, Jackson Bird, Nathan Lyon (12th man).
