Editing Bowling (cricket) (section)

===Pace and movement===
Other than the ability to land the ball on a strategically optimum line and length, the main weapons of the bowler are his ability to move the ball sideways as it approaches the batter and his ability to deliver the ball at a high velocity.

The velocities of cricket bowlers vary between {{convert|40|and|100|mph|0|abbr=on}}. In professional cricket, a bowler in the 40–60&nbsp;mph range would be said to be a slow bowler, in the 60–80&nbsp;mph range a medium pace bowler, and a bowler 80&nbsp;mph+ a fast bowler. In the amateur game, these distinctions would be approximately 10&nbsp;mph slower. Many professional fast bowlers are able to reach speeds of over 85&nbsp;mph, with a handful of bowlers in the world able to bowl at 95&nbsp;mph+. The ability to react to a cricket ball travelling at 85&nbsp;mph is a skill that only professional and high level amateur cricketers possess. The pace of a bowler not only challenges the reaction speed of the batter, but also his physical courage. Fast bowlers are able to exploit this by bowling bouncers, either regularly or as an occasional surprise delivery.

Bowlers are also able to get the ball to move sideways by using either ''spin'' or ''swing''. Adding a spin to a cricket ball will make it deviate due to the [[Magnus effect]] in its flight (like a [[slider (pitch)|slider]] in baseball), and then produce sideways movement off the ground. Swing is obtained by using air pressure differences caused by angling the seam of the cricket ball to produce a lateral movement in the air. Fast bowlers will generally only use swing to obtain movement, but medium pace and slow bowlers will often use a combination of the two. The intention is that in creating movement in the delivery, the batter will misjudge the line of the ball as it arrives, causing him to miss it entirely, in which case he may be dismissed bowled or lbw, or miss-hit it, in which case he may be out caught.

To avoid becoming predictable, a bowler will typically bowl a variety of different deliveries with different combinations of pace and movement. A tactically astute bowler may be able to spot a potential weakness in a batter that a particular delivery may be able to exploit. Bowlers will often also bowl deliveries in preplanned sets, with the intention of dismissing the batter with the final delivery in the set. This is known as "setting a trap" for the batter.<ref>{{Cite web|title=England v Sri Lanka: Story of day five at Lord's|url=https://www.skysports.com/cricket/news/12123/10312877/england-v-sri-lanka-story-of-day-five-at-lords|access-date=2020-09-11|website=Sky Sports|language=en}}</ref> batters and bowlers will often also engage in a game of "cat and mouse", in which the bowler varies his tactics to try and trap and dismiss the batter, but the batter also keeps adjusting his tactics in response.
