The Fabulous Four (Fab Four) is a term that cricket pundits came up with in order to club together the top four Test batters of the modern era. India’s Virat Kohli, England’s Joe Root, Australia’s Steve Smith, and New Zealand’s Kane Williamson made the list. All these players have been producing top performances so far for their respective countries in ODIs over all these years.
However, they have also batted at the number four position on many occasions. The Number four spot in ODI demands a player who can stabilize the innings, build partnerships, and accelerate the run rate when required. So, over the years, these players have tried their best to emulate these traits and managed to come up with some significant contributions.

Kane Williamson:

This Kiwi batter has batted only on 10 occasions so far at this position. Kane Williamson has scored 221 runs, at an average of 22.10 with a strike rate of 64.43. He has only two fifties to his name at this position. However, Williamson has batted mostly at the number three position in his career so far.
From 2010 to 2013, New Zealand tried him in this position. But, since his first chance in 2013 at the number three position, Williamson has never looked back. His best score in this position is 58 runs off 65 balls, including four boundaries and one six against West Indies in the second ODI of the series in 2012.
