Fast bowling
The mixture of speed, seam and swing that can be achieved depends on several factors, including the individual bowler's skill, the condition of the ball, and the weather.However, there is no universally accepted set of definitions and the categorization of bowlers according to speed may take into account competition level[4] and gender.Typically, strike bowlers work in short spells, either at the start of an innings or to confront new batters, although they are also employed tactically at other times.More commonly, however, a combined approach is adopted to produce balls that the batter finds difficult or impossible to play, whatever the speed at which they are delivered.[14] In most cases the outswinger is seen as the more dangerous ball because, if the batter fails to recognise it, it catches the outside edge of the bat instead of the middle and fly up to be caught in the slips.It is difficult to achieve swing with a cutter grip since the ball spins in flight, varying the orientation of the shiny and rough surfaces as it moves through the air.The discovery of reverse swing is credited to Pakistan's cricketers, with Sarfraz Nawaz and Farrukh Ahmed Khan, both named as originators of the delivery.However, as of 2019, injury rates are at their lowest in decades, in many parts thanks to advances in physical conditioning, sport science, and load management interventions.
