Early in Siddle's career he faced injury problems, but he overcame them in 2009 to be named the ICC Emerging Player of the Year. Though injuries continued to plague him throughout his career, he rose to prominence in the 2010–11 Ashes series when he became the ninth Australian to take a Test hat-trick and the first Australian since Shane Warne in 1994-95 to do so in an Ashes test. He remained a regular fixture in Australia's team until his bowling pace started to drop in 2014, with Australia's selectors beginning to focus on younger, faster bowlers.
