Almost bowling
Fast bowling , also known as pace bowling known in is cricket to bowl one of the two main types. Users of this technique are known as fast bowlers or pace bowlers. The other main style is spin bowling . The main goal of almost bowling is to bowl the cricket ball at high speed so that the ball bounces off the pitch irregularly . This makes it difficult for the batsman to hit the ball properly. This reaches speeds of 136 to 150 km / h. The fastest speed ever recorded is 161.3 km / h, bowled by Shoaib Akhtar of Pakistan in the game against England at the 2003 World Cup.

There are generally two sub-categories of almost bowling.
Seam bowling
The seam bowling is often used synonymously with the almost bowling. The ball is held with the index and middle finger above and the thumb below the ball. The seam runs between the upper two fingers while the thumb rests on it. The aim of the bowler is to bowl the ball as straight as possible leaving the hand so that the ball hits the bottom of the pitch with the seam as possible. This creates the possibility that the ball receives changes in direction that make it more difficult for the batsmen to correctly assess the trajectory of the ball.
Swing bowling
The swing bowling is based on the fact that the ball will wear in the course of the game. As the ball hits the ground and hits the racket, the surface of the ball gradually roughened. The players of the field team are allowed to rub the ball on their clothing, which smooths the surface of the ball again. Because the field players always rub the ball on the same side, a smooth and a rough side is created in the course of the game. If the ball is bowled in such a way that when it leaves the hand, the rough side of the ball is on one side and the smooth side of the ball on the other, there will be different air currents on the ball surface. While the air can flow past unhindered on the smooth side, it swirls on the rough side. This causes the ball to change direction in the air and move sideways from the batsmen's point of view, making it more difficult for him to assess. A basic distinction is made between the outswinger and the inswinger . Slight changes in the position of the index and middle fingers and the correct position of the rough side ensure that the ball turns towards or away from the batsmen. If the ball wears out more, the effect of the so-called reverse swing can occur. The ball rotates against the original direction (i.e. an inswinger becomes an outswinger and vice versa). The Pakistani international Sarfraz Nawaz first used this effect in a targeted manner in the late 1970s. In order to enable a ball to reproduce this effect at an early stage, it is the task of the whole team to let the ball hit the ground as hard as possible while bowling and to always rub the right side of the ball on the clothing.
classification
Successful bowlers use various fast bowling techniques, as simple fast bowling is easy to understand. The bowlers are usually classified according to their speed. A common classification is given in the following table:
| designation | km / h | mph |
|---|---|---|
| Nearly | 145+ | 90+ |
| Almost-medium | 129-145 | 80-89 |
| Medium-fast | 113-129 | 70-79 |
| medium | 97-113 | 60-69 |
| Medium-slow | 80-97 | 50-59 |
| Slow medium | 64-80 | 40-49 |
| Slow | <64 | <40 |
length
In addition to speed, the ball is also classified according to its height as it arrives on the batsmen's side. A distinction is first made between the balls that do not hit the ground and are hit directly from the air by the batsmen ( no toss ) and those that first touch the ground. There are then five classically named heights. If the ball lands directly on or near the line of the batsmen, a ball is called a Yorker . A ball that arrives at about hip height when batsmen is called good length . The so-called full pitch is located between these two . If the ball bounces on the ground at chest height after it has hit the ground, it is called short pitched . Above that is the bouncer aiming at the batsmen's head. Should the bouncer fly over his head, he will be rated wide by the umpire , which means a run for the batting team.
