For the second day running the opening Test has had a genuine controversy of the day on its hands. On Thursday the course of the match was changed by two dubious DRS decisions, but while Australia benefitted then they were left furious this time around.
It was not a review, but the lack of one which triggered the incident as Stuart Broad - facing Agar - deflected one off the gloves of wicket-keeper Brad Haddin into the hands of Clarke at slip.
First impressions indicated that Broad had hit the ball and the replays confirmed a significant edge, but umpire Aleem Dar did not pick it up and the finger wasn't raised.
Australia had no reviews remaining and, with Broad being unwilling to walk as his team-mate Jonny Bairstow had earlier in the day, his innings was allowed to continue.
And finally...
Shane Watson may not be the most explosive bowler Australia have, but he was certainly the most economical on day three. At one point the steady seamer had staggering second-innings figures of 13 overs, 11 maidens, 0-3. Although he conceded eight runs from his final two overs he finished with 15 overs, 11 maidens and an economy rate of 0.73.
