Jonny Bairstow smashed the second-fastest fifty by an English batter in Test cricket

Bairstow took just 30 deliveries on Day 5 of third Test vs New Zealand to reach fifty

The record for fastest Test fifty for England belongs to Ian Botham

Former England skipper Botham scored 28-ball half-century vs India in 1981

Recently, Bairstow broke the record for fastest century for England as well (77 balls)

Bairstow scored 394 runs at an average of 78.80 and strike rate of 120.12 in the series
