Ashes 2010: The best pictures from day two of the fourth Test

Peter Siddle to begin. He was Australia's best bowler yesterday, and he finds a full length from the start Photograph: Mark Dadswell/Getty Images

WICKET! England 159-1 (Cook c Watson b Siddle 82) Alastair Cook misses out on his third century, but there's no shame in falling to a fine delivery from Siddle. That was an excellent piece of bowling Photograph: Mark Dadswell/Getty Images

WICKET! England 170-2 (Strauss c Hussey b Siddle 69) Strauss is turned round by a nasty lifter on leg and middle, and the ball flies off the shoulder of the bat towards backward point, where Mike Hussey leaps and extends his telescopic arm to take an outstanding one-handed catch. I told you Siddle shouldn't have been on this morning! Photograph: Andrew Brownbill/AP

Kevin Pietersen steps up... Photograph: Hamish Blair/Getty Images

84th over: England 259-2 (Trott 45, Pietersen 49) Pietersen pushes forward defensively at Harris, who doesn't appeal at all for the caught behind. Haddin does, however, and when Aleem Dar says not out Australia go for the review. Pietersen is not out. But Australia are furious, not least Ricky Ponting Photograph: Hamish Blair/Getty Images

WICKET! England 262-3 (Pietersen LBW b Siddle 51) Peter Siddle strikes with the third ball of his new spell. Pietersen jumped back in his crease and missed an attempted whip at a straight one that kept a touch low and would have hit leg stump halfway up. That was plumb Photograph: Gareth Copley/PA

WICKET! England 281-4 (Collingwood c Siddle b Johnson 8) Another bowling change brings an instant wicket. Mitchell Johnson returns and strikes with his third ball, which Collingwood pulls right down the throat of Siddle at fine leg. Australia celebrate in a way that suggests they still feel they are in this Test Photograph: Mark Dadswell/Getty Images

WICKET! England 286-5 (Bell c Siddle b Johnson 1) Bell tried to hook a good short ball from Johnson that was too high and too wide for him to control the stroke, and Siddle at fine leg charged in to take a brilliant low catch as he tumbled forward Photograph: Quinn Rooney/Getty Images

105th over: England 317-5 (Trott 76, Prior 14) Trott inside edges Hilfenhaus right onto the kneebone and collapses to the floor. He is in a lot of pain. He really is struggling, but after a couple of minutes' treatment he gets to his feet, swallows a couple of painkillers and resumes his innings Photograph: Jason O'Brien/Action Images

118th over: England 365-5 (Trott 106, Prior 32) Trott reaches an excellent century with his favourite shot, a flip through midwicket for four off Harris. It's his third hundred against Australia in only five Tests, and his fifth overall Photograph: Scott Barbour/Getty Images

136th over: England 444-5 (Trott 141, Prior 75) Trott acknowledges the crowd at the end of another superb day for England, who lead by 346 and are so close to retaining the Ashes Photograph: Tom Shaw/Getty Images
