In his first Test match back, on 25 November 2010, Siddle's 26th birthday, he became the ninth Australian to take a Test hat-trick. Siddle had been controversially brought into the Australian side ahead of Doug Bollinger despite not having played since January, but he proved doubters wrong early in the match by taking the key wickets of Kevin Pietersen and Paul Collingwood early in England's first innings. When England had reached 4/197, Siddle was brought back into the attack and took the wickets of Alastair Cook and Matt Prior in consecutive balls to be on a hat-trick. Stuart Broad came to the crease for the hat-trick ball, on which Siddle bowled a yorker. Broad missed the ball with his bat, so it hit his foot and he was given out leg before wicket. Broad referred the decision to the third umpire, but the wicket was not overturned. Siddle went on to dismiss Graeme Swann for his sixth wicket of the innings and almost took a seventh when wicket-keeper Brad Haddin dropped James Anderson off his bowling. He finished with figures of six wickets for just 54 runs, his best ever in Test match cricket, having bowled 16 overs in total.
