4. Most Test five-wicket hauls in a calendar year:

The record of most five-wicket hauls is currently held by Sri Lankan great Muttiah Muralitharan and West Indies’ Malcolm Marshall who both took 9 five-wicket hauls in 2006 and 1984 respectively. And Ashwin already has four five-wicket hauls after the conclusion of the first Test against New Zealand.
With still 7 matches to be played before the end of 2016, one can pin their hopes on the star off-spinner. Last year he came agonisingly close to breaking that record when he fell short by just two five-wicket hauls after taking an impressive seven in only nine Tests.
