Bowlers who never conceded a six in Test Cricket #euphoriacricket

I have been seeing posts on Instagram which state that Curtly Ambrose has never been hit for a 6 in his entire Test career, as amazing as that sounds it’s simply not true. However, there are 5 bowlers who bowled more than 5,000 balls in test cricket but never got hit for a 6. Those 5 bowlers are Derek Pringle (ENG) 5287 balls, Mahmood Hussain (PAK) 5910 balls, Mudassar Nazar (PAK) 5967 balls, Neil Hawke (AUS) 6987 balls and Keith Miller (AUS) 10461 balls.
