FAST BOWLING

PACE BOWLING:

Fast bowling, sometimes known as pace bowling, is one of the two main approaches to bowling in the sport of cricket.The aim of fast bowling is to bowl the hard cricket ball at high speed and to induce it to bounce off the pitch in an erratic fashion or move sideways through the air, factors which make it difficult for the batsman to hit the ball cleanly. A typical fast delivery has a speed in the range of 137–153 km/h.

Classification of fast bowlers:                                

Type	km/h	mph
Fast	≥142	≥89
Fast-Medium	130-141	81-88
Medium-Fast	120-129	75-80
Medium	96-119	60-74

SWING BOWLING:

Swing bowlers cause the ball to move laterally through the air.Conventional swing is usually greatest when the ball is new and therefore has a pronounced seam. As the ball gets older, the wear makes swing more difficult to achieve.When the ball has been polished highly on one side and not on the other and if the ball is bowled very fast (over 85 miles per hour), it produces a reverse swing such that the ball swings in the opposite direction as in conventional swing.
