Bairstow reached the landmark in just 21 deliveries during the second ODI against Ireland at the Ageas Bowl on Saturday.

The fastest ever ODI fifty belongs to AB de Villiers.
The South Africa batsman reached the milestone in just 16 balls during his remarkable knock of 149 against West Indies in Johannesburg in 2015.
