<p class="title">White-ball specialist batsman Aaron Finch and South Australia captain Travis Head will make their Test debuts in the series-opener against Pakistan in Dubai on Sunday, Australia coach Justin Langer has confirmed.</p>.<p class="bodytext">Both players scored half-centuries in Australia's drawn tour match against a Pakistan A side, convincing Langer to award them their first caps in the five-day format.</p>.<p class="bodytext">"There was never any doubt over those two for me, I thought they were certainties to play," Langer said of his first test side as Australia coach after the former opener took over from Darren Lehmann in May.</p>.<p class="bodytext">Despite the pair making certain of selection, doubts remain in other areas of captain Tim Paine's team, with opener Matt Renshaw picking up a head injury after being struck by the ball during the tour game that ended on Tuesday.</p>.<p class="bodytext">"I think Matthew Renshaw will be physically fine -- the one thing he's got is he hasn't played much cricket," Langer told reporters in Dubai.</p>.<p class="bodytext">"He went on Australia A trip, he got a hamstring strain... he hasn't spent much time in the middle. That's going to be the issue for him.</p>.<p class="bodytext">"It's going to be an instinct call. We've got to weigh up what he's done in the past. He's obviously a very good young player. We've got to work out whether he's spent enough time out in the middle to be ready for a test match."</p>.<p class="bodytext">Renshaw's possible absence could pave the way for South Africa-born Marnus Labuschagne, who came in at number six against Pakistan A and scored an unbeaten 39 in Australia's only innings.</p>.<p class="bodytext">The 24-year-old, who can also bowl part-time leg spin, was a surprise inclusion in the 15-man squad but played a key role in Queensland's Sheffield Shield triumph earlier this year.</p>.<p class="bodytext">"We've seen in the history of Australian cricket a lot of people take their opportunities through injury," Langer said.</p>.<p class="bodytext">"I thought Marnus fielded brilliantly but was really good with the bat (against Pakistan A), bowled a few overs. He's certainly put a strong case forward for selection as well."</p>
