Seam bowling
（重定向自Seam bowler）
Seam bowling is a phrase used for a bowling technique in cricket whereby the ball is deliberately bowled on to its seam, to cause a random deviation. Practitioners are known as seam bowlers or seamers.
Seam bowling is generally classed as a subtype of fast bowling, although the bowling speeds at which seam can be a factor include medium-pace bowling. Although there are specialist seamers that make deliberate use of Off cutter and Leg cutter at the expense of bowling slower than regular fast bowlers, most bowlers employ the seam to some effect and so the terms "seamer" and "fast bowler" are largely synonymous.
