Sydney, Jan 2 (Reporter) With the chance to claim both Border-Gavaskar Trophy honours and a spot in the World Test Championship Final, Pat Cummins and Australia have confirmed a selection change for Sydney. Australia have dropped a selection surprise on the eve of the final Border-Gavaskar Trophy Test in Sydney, omitting all-rounder Mitch Marsh with series honours and a World Test Championship Final opportunities on the line. It means Beau Webster will enter the playing XI as the second debutant in as many Tests after Sam Konstas' electric entry in Melbourne. Webster, set to become the 469th Test player for Australia, is the preferred sixth batter for the side, with Pat Cummins confirming there were no fitness concerns for Marsh despite minor back complaints earlier in the series. Averaging just 10.42 for the series and not providing cut-through with his overs of pace bowling, Marsh gives way to Webster, whose recent first-class bowling numbers, and a quick turnaround from the Melbourne Test, also contributed to the change, an ICC report said. Webster claimed 12 wickets across his last three first-class outing, taking six wickets and making an unbeaten 46 not out in the most recent Australia A v India A meeting in Melbourne. Mitchell Starc meanwhile keeps his place in the side, declared fit in spite of rib soreness sustained in the Melbourne victory.
