Pace bowlers
Main article: Fast bowling
Pace bowlers, or fast bowlers or pacemen, rely on speed to get a batsman out. This type of bowler can be further classified according to the speed at which they bowl the ball on average. For details see Fast bowling.
Most pace bowlers are medium-fast to fast in top level cricket. In general, bowlers of this type are described as right arm or left arm "fast", or right arm or left arm "fast-medium", and so on. The fastest bowler ever in the cricket history was Australian Jeff Thomson. Due to the unavailability of ball speed measuring devices his bowling speed couldn't be measured in every match. In 1975 during a Test match, he was timed using high-speed cameras with a release speed of 160.45 km/h; the following year he was timed at 160.58 km/h using conventional radar. But these speeds were measured at the batting end. Nowadays bowling speed is measured just at the instance when bowler releases the ball. So if this technique was used in old times, Jeff Thomson would have probably been clocked at more than 170 km/h. Australian wicket-keeper Rod Marsh kept wicket to Thomson for most of his Test career and claimed that Thomson bowled upwards of 180 km/h. The fastest delivery that has ever been officially recorded clocked in at 100.2 mph (162.26kph) and was bowled by Shoaib Akhtar Pakistan during a match against England. Another technique of fast bowling is the sling action. This action generates extra speed but sacrifices control. Some bowlers who apply the sling action are Shaun Tait, Mitchell Johnson, Rubel Hossain, Fidel Edwards and Lasith Malinga
Swing bowlers
Swing bowlers are pace bowlers who, apart from being fast, also use the seam of the ball to make it travel in a curved path through the air. This is further encouraged by systematically polishing one side of the ball while allowing the other side to become roughened and worn. The differing airflow around the two sides will cause the ball to swing in the air, towards the roughened side. By changing the orientation of the ball in his hand, a bowler may therefore cause the ball to swing into or away from the batsman. In addition to a well-polished ball, other factors help the ball to swing, notably damp or humid weather conditions. However balls which have been in play for some time do not tend to swing so much due to the deterioration of the seam. In addition, bowlers of express pace do not tend to get as much swing as the fast-medium-to-medium pace bowlers.
Though younger pace bowlers tend to rely exclusively on speed, as bowlers age they tend to develop this more sophisticated art of swing bowling. Swing bowlers are more effective than sheer pace bowlers as the swing can confuse a batsman. Wasim Akram and Waqar Younis of Pakistan were masters of this skill, and were capable of causing an older, misshapen ball to swing the opposite way from normal, i.e. toward the shiny side. This is known as reverse swing and has become an increasingly important skill in the last 10 to 15 years.
Wrist spin
Wrist spinners are bowlers who use their wrists to spin the ball. A right-handed wrist spinner is known as a leg spinner and his or her mode of bowling is known as leg break. A leg break will move from right to left from the bowler's point of view, or from the leg-side to the off-side for a right-handed batsman. Shane Warne of Australia and Anil Kumble of India are amongst the most successful bowlers in Test cricket history. Shahid Afridi of Pakistan is amongst contemporary bowlers of this type.
Left-handed wrist spinners, who are much rarer than right-handed wrist-spinners, are called chinaman bowlers, after an early left-arm finger spinner of Chinese descent, Ellis Achong, who sometimes bowled wrist spinners as a variation while playing for the West Indies. A ball delivered in this way will spin from the off-side to the leg-side for a right-handed batsman. Paul Adams of South Africa is the best-known current chinaman bowler, though he no longer features in his country's national side. Australian one-day all-rounder Brad Hogg is another current exponent of left-arm wrist-spin, as is his teammate, batsman Simon Katich. Beau Casson, another Australian is another fine left arm chinaman bowler.
Finger spin
Finger spinners make use of their fingers to rotate the ball. A right-arm finger spinner is known as an off-spinner and their mode of bowling is known as off break. The ball will appear to move just as the chinaman does, from off to leg for a right-handed batsman. Muttiah Muralitharan of Sri Lanka, one of the most successful bowlers in Test and ODI cricket history, is an off-spinner, although his bowling style is unusual. Saqlain Mushtaq was also a succcessful bowler in this format. Indian Harbhajan Singh and Pakistani Saeed Ajmal are current bowlers who also employ this bowling style .
Almost all left-handed bowlers are finger spinners. As a result this style has no fixed name and the bowling mode is simply known as (slow) left-arm orthodox. The ball turns like a leg break, from leg to off. Shakib Al Hasan of Bangladesh and New Zealand's Daniel Vettori employ this bowling style.
