Australia made a steady start to their innings after being sent in to bat by England on a lively pitch on the opening day of the final Ashes Test Friday, reaching drinks at 44 for one. The Australians, bidding for a 5-0 series clean sweep, lost the wicket of David Warner, bowled by Stuart Broad for 16 in the sixth over at the Sydney Cricket Ground after the batsman reached 500 runs for the series. Warner got tangled up with his footwork as Broad beat him off the pitch to take his off-stump, leaving the home side at 22-1. Warner is the leading runscorer in the series with 507  runs at 63.37. Chris Rogers was 10 not out at drinks and Shane Watson was unbeaten on 18. Alastair Cook earlier won his first toss of the series and put Australia in on a green-tinged SCG pitch. England made three changes from the team beaten by eight wickets in the fourth Test in Melbourne, handing Test debuts to middle-order batsman Gary Ballance, leg-spinner Scott Borthwick and paceman Boyd Rankin. It is the first time that England have played three newcomers in a Test since 2006 and means the tourists have used 18 players over the five Tests. Australia, who are chasing a 5-0 series whitewash for only the third time in Ashes history, remained unchanged for the fifth consecutive Test. England sprung a surprise by dropping Joe Root and elevating Ian Bell to number three, while Michael Carberry kept his place at the top of the order, despite concerns over his slow rate of scoring. Root, 22, paid the price for scoring just 192 runs at 27.42. Young leg-spinner Borthwick came in for Monty Panesar, while speedster Rankin got his chance at the expense of Tim Bresnan. All-rounder Shane Watson (groin) and paceman Ryan Harris (knee) were cleared to play for Australia to remain changed . Player of the series Mitchell Johnson needs nine wickets to become the fourth Australian bowler to take 40 wickets or more in an Ashes series along with Terry Alderman (twice), Rodney Hogg and Shane Warne. Of those, only Warne took his 40 wickets in a five-Test series. Source: AFP
