In a shocking finish to a quite dramatic day in Wellington, New Zealand captain Tim Southee dropped a sitter of Nathan Lyon on the last ball before stumps to deprive his team of the chance to end the day with three Australian wickets in the bag.Matt Henry pitched a delivery on a perfect length outside the off-stump. Lyon, who had come out as a nightwatchman after the fall of two early wickets, hung his bat out helplessly. The ball took a thick outside edge to third slip. Southee, who was just a bit too excited and a bit too forward, couldn't hold on to the chance.Watch the video here:The build-up to the drop was dramatic too. Lyon picked up an injury a few overs before which required a couple of interventions from the physio. The Kiwi crowd booed the Aussie for it, believing he was trying to waste time.In the last over, Lyon's partner Usman Khawaja took a single on the fourth ball and gave the veteran spinner a couple of words of motivation for the final two deliveries. So, Henry and company brought in all the fielders, setting up a ring of close-in men around the right-handed batter.The fifth ball was a waste down-the-leg short one but the final one certainly deserved a wicket.New Zealand couldn't be angry at Tim Southee eitherIt was the captain himself who picked up the first two wickets, which the hosts desperately needed after conceding a big 204-run lead in the first innings. Southee got Steven Smith out for a duck on the third ball of the first over and then had Marnus Labuschagne edge one behind the keeper off a tickle down the leg.Australia went to Stumps at 13/2, leading by 217 runs. New Zealand would need wickets early Saturday morning to even have a chance of a comeback in the Test.
