Pick of the day
We select the best of the Ashes action from Trent Bridge
Last Updated: 12/07/13 11:28am
Peter Siddle claimed 5-50 as England were dismissed for 215 after opting to bat but Australia also struggled with the bat, closing on 75-4 in reply with two wickets each for James Anderson and Steven Finn.
With the dust having settled on a frenetic day, we pick out some of the best moments.
Siddle deserves a mention for the yorker he produced to bowl Joe Root but Anderson delivered the ball of the day to send Australia captain Michael Clarke on his way for a duck.
Clarke played-and-missed at Finn's hat-trick effort after arriving at the crease with Australia tottering at 19-2 in reply to England's 215.
But he was soon on his way when Anderson conjured up a beauty in the seventh over of the innings that shaped in through the air and went away off the pitch to knock back off-stump.
Clarke had to play because of the angle but was left unable to cover his stumps when the ball changed direction off the pitch.
There was plenty of good slip catching on display from both sides with Root's effort to remove Shane Watson our pick of the bunch.
The 22-year-old is the newest addition to England's cordon but showed his reactions are up to the job after Watson's thick edge flew quickly to him.
Root's grab was the start of an England fightback, the first of four Australian wickets to go down against the new ball.
Volume turned up
The crowd were relatively subdued for much of the day before coming to life as England fought back in the evening session.
When Finn struck for the second time in as many deliveries in the fourth over of Australia's reply, the roar around the ground was partly celebration and partly relief at the realisation England's first-innings total was not as bad as feared.
Anderson than picked up from Finn and, with Clarke and Chris Rogers on their way back before the close, it was hard to say who had enjoyed the better day.
England's No.10 Finn was caught behind first ball but at least showed he is learning how to act like a proper batsman.
After edging a delivery from Mitchell Starc through to wicketkeeper Brad Haddin, Finn gave his best poker face to the umpire while signalling for a review.
England still had two remaining and, with only Anderson left to come, there was nothing much to lose by sending the decision upstairs.
Unfortunately for Finn, the Hotspot replay showed a clear mark on his outside edge and Starc's front foot had remained safely behind the line. He was sent on his way.
Australia surprised everyone when Ashton Agar was handed his Baggy Green on the outfield by Glenn McGrath in the morning.
The left-arm spinner, 19, was preferred to Nathan Lyon as Australia's lone slow bowler, a decision that coach Darren Lehmann explained was due to the large number of right-handers in England batting line-up.
Agar became the 16th teenager to play Test cricket for Australia and was into the attack in just the 16th over of the day.
His first ball was a full toss that Jonathan Trott hit for four through the covers but he settled down thereafter, getting through seven overs for figures of 0-24.
