Western Australia missing fit stars Mitch Marsh and Nathan Coulter-Nile for Sheffield Shield match against Queensland Mitch Marsh won't line up for WA in tomorrow's Shield match. WESTERN Australia coach Justin Langer couldn't help but feel a tad frustrated today as he watched a fit-and-firing Mitchell Marsh steam in to bowl at training. Marsh was one of the very few positives to come out of Australia's disastrous 2-0 Test series loss to Pakistan in the United Arab Emirates, with the 23-year-old showcasing his potential with scores of 87 and 47 in the second Test. The West Australian arrived back in Perth earlier this week and looked sharp while bowling to his Warriors" teammates at training on Friday. But that's of little consolation to Langer, who will have to do without Marsh and star allrounder Nathan Coulter-Nile for the day-night Sheffield Shield clash with Queensland at the WACA, starting on Saturday. Both players have been ordered to rest ahead of Australia's five-match one-day series against South Africa, their absence robbing WA of vital firepower with both bat and ball. "It's frustrating for everyone, but we also know it's a long summer," a diplomatic Langer said. We've seen it throughout our Champions League, through the whole one-day tournament - trying to manage your bowlers and keep them fresh, knowing what's coming up, is a real managerial nightmare. So I can understand why they're not playing this game. Ashton Turner has replaced Coulter-Nile in WA's 12-man squad, while Queensland have recalled batsman Greg Moller and allrounder Michael Neser to replace Ryan Le Roux and Ben McDermott. WA struggled badly with the bat in last summer's day-night Shield clash against Queensland, with the Warriors skittled for 175 and 144 in their two innings. Langer knows batting against the experimental pink ball under lights can be tough, but he hopes his players won't be too daunted by the task. "Last year, we put a lot of effort, emphasis and thinking into it, and maybe that distracted us a bit," Langer said. So we're going to keep to our processes and realise it's just a different colour. Cricket Australia hopes to pioneer a day-night Test match by as early as next summer, and Langer feels a white ball might be a better answer than the pink, which becomes hard to see under lights.
