ICC announced a ban on sixes straight down the ground in 2013 to tribute to former great England Cricket captain and great commentator Tony Greig who has died after suffering a heart attack. He was 66.
ICC President Alan Isaac said "We stopped all the sixes straight down the ground in 2013 as a glorious career of captain and mostly a great commentator has ended today. This is tribute to a guy who just not entertained but excited us to watch the cricket match. He made us stick to a match and increased our affection towards cricket. Now as we don't have a guy who excites us with his great voice and statement 'Straight down the ground all they way for six' we banned any six or even four straight down the ground in 2013. 2013 will be a Tony Greig year. Tony we will miss you."
