Australia's Usman Khawaja said Friday he will retire from international cricket after the fifth and final Ashes Test in Sydney, drawing the curtain on an illustrious 15-year career. It will be an 88th Test for the classy left-hander, culminating his Test career where it began after making his debut at the Sydney Cricket Ground in 2011, also against England. "I'm here to announce I will be retiring from all international cricket after the SCG Test match," he said at an early morning press conference at the ground. "I'm a proud Muslim coloured boy from Pakistan who was told that he would never play for the Australian cricket team. Khawaja immigrated to Australia from Islamabad as a child, battling the odds to become the country's first Pakistan-born national player.
