Ashes 2013-14: Five things we learned on day two of the fourth Test between Australia and England The two players jeered and booed by the crowds have produced the perfect riposte. Mitchell Johnson is having the series of his life and Stuart Broad, the subject of "Broad is a w*****" chants all day at the MCG, is coming of age by finally delivering away from home comforts. Broad's record abroad before this tour was below standard for a bowler of his calibre, with his wickets costing 40 each and injury wrecking trips to Australia and India. He took just one on the last Ashes tour before injury struck him down in the second Test. But this time he bowled the right length from the first day of the series at the Gabba and has not looked back. He has 17 wickets at 22.52, is full of confidence and assumed the leadership of the attack. Before today that accolade went to Johnson at the start of England's first innings at Adelaide but this morning he blew away any hope of a late assault from Pietersen and the tail. He started from ball one with Bresnan popping a bouncer to short leg. It wasn't the quickest delivery Johnson has bowled, it was around 88mph, but it was aimed at the left armpit and for a tailender feeling the nerves of facing the fastest man in the series, that was enough. Two balls later another bouncer forced Pietersen to pull out of a big heave over midwicket. Next ball had a touch of inswing to beat Pietersen's mow to the legside and hit the stumps. Two overs later and it was a repeat of Perth as Broad was hit just above the bootlaces by a yorker and Johnson had 5-18 with the second new ball. Bairstow's big day His first day keeping in international cricket went according to plan. He is not as polished as Matt Prior but he kept tidily to the spinner and was athletic and strong keeping to the quicks. He was full of Prior-like energy running down the ground to chase the ball to fine leg and throwing the ball strongly to the non-striker's end to attempt a run out. His first test came off the first ball of the innings. A loud lbw shout was turned down and Bairstow was part of the brains trust which rightly did not call for the review. His weakness was diving to his left to the quicks but England's accuracy in the channel outside off stump meant he did not have to do that too often. He geed up the fielders running down to long leg to congratulate Panesar on a regulation (even for Monty) piece of fielding. Will he be the long-term England keeper? Prior will come back and England have identified Ben Foakes of Essex as a possible long-term successor. Bell grabs his chance England's slip cordon has gone through a complete transformation since the last Ashes tour when it was so reliable with the Strauss-Swann-Collingwood combination. Cook moved into the Strauss role last year when he took over as captain and Trott took on the third slip position following Collingwood's retirement. Bell worked hard this week preparing for his promotion into Swann's slot at second slip and he took the only chance that came his way. Steve Smith slashed hard and, despite the ball deviating through the air, Bell readjusted and held on with two hands. This batting business is quite hard The bruises will have been worth it for Piers Morgan, totally unknown in Australia until a twitter rant at English batsmen brought him a crack at facing Brett Lee in the MCG nets which was beamed live by Channel 9, boosting the former Daily Mirror's editor's profile in this part of the world. A crowd of 5,000 for some reason lined the nets at the Gee hoping for some Pommie blood. Piers claimed he was told to go down the pitch to Lee by Viv Richards. To everyone else it looked like backing away, particularly as he tumbled into the side netting. He was hit four times by a 37 year-old Lee bowling, he judged, at "80 percent" of his capacity.
