526:), with the seam remaining broadly upright but oscillating repeatedly between a 5 o'clock and 7 o'clock position (if viewed from the bottom of the seam). This effectively destroys seam induced swing (as the ball is constantly changing between outswing and inswing seam positions through the air). Thus, the ball travels straight onto the pitch (in theory allowing the bowler to be more accurate). However, when the seam of the ball contacts the pitch at the 5 o'clock position, the result is movement to the left (away to the right-handed batter), when the seam of the ball contacts the pitch at the 7 o'clock position, the result is movement to the right (in to the right-handed batter). It can be seen that only rarely would the ball be at the purely 6 o'clock position to continue completely straight after pitching. This aligns with the unpredictable nature of seam bowling, but appears primarily driven by the technique of the bowler, rather than irregularities in the pitch surface.

449:, making it likely that the ball will bounce with the seam on the pitch. Consistently hitting the seam is not as easy as it sounds. The seam has to be held upright between the index finger and the middle finger at the time of the delivery of the ball and, most importantly, the wrist has to be dead straight when the ball is delivered. The seam and wrist position of Australia's

employed a leg cutter of this sort to considerable effect; however, deliveries of this kind will be slower than if the bowler simply bowls with the seam upright, hoping for movement one way or the other. Some bowlers deliberately use cutters more for their surprise slowness than the deviation off the
419:
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. This was far less the case in the past, even the recent past. Bowlers such as Tom
Cartwright and Derek Shackleton bowled seamers

when it bounces, this irregularity can cause the ball to deviate sideways in its path. It may move in any direction, or just go straight. The batsman has to see how the ball moves after pitching to select his shot.
456:
The direction and degree of the ball's deviation from a straight path are dependent on the small-scale alignment of the seam and any irregularities in the pitch surface. This means that deviation caused by seam is

In order to achieve this effect, a seam bowler usually delivers the ball with the seam held upright, with rotation about a horizontal axis. This keeps the seam aligned vertically as it travels towards the

Often the deviation caused by seam is not large enough to cause a batter significant problems with playing the ball. Occasionally, however, the ball can deviate far enough to hit the edge of the
