Alastair Cook's 33rd and final test century in his farewell match for England is the yin to the yang of the last man to achieve the feat.
Brendon McCullum is almost the polar opposite to Cook, styles as different as they could be.
Those who were at Hagley Oval on a sunlit day in early 2016 won't forget what they saw, the day McCullum smashed the record for the world's fastest test ton in his last match.
Where Cook, in his measured, pragmatic way, made his 146 off 286 balls at The Oval against India yesterday and retires one of the alltime great test batsmen, McCullum did his business in a starkly different manner.
He arrived with New Zealand in a parlous state at 32 for three against Australia, played and missed his first ball from seamer Mitchell Marsh, then heaved his second ball over slips – ''an almighty, filthy slog'' he called it -- and he was off.
