It might be easy to draw a line between Bairstow’s stunning catch off Mitchell Marsh on the first evening and this innings, but the trend of a career suggests the theory has substance, each event, for better or worse, influenced by the last. This was the Bairstow that launched the revolution in a summer-long snowball twelve months ago, dispatching those logic-defying punch-pulls for six, bat-face turning down as ball, somehow, flies up. Australia must be losing count of the time spent in this series with nine on the fence standing helpless guard. The longest of Bairstow’s four maximums rendered not only the sentries, but all bar the back row of spectators obsolete, as well.
