Why Swing Bowling is nightmare for every Batsman in Cricket?

It is a fact that even the most experienced, most technically sound batsman will fall under the trap of good swing bowling especially late swing..

Ever wondered why it is like that?. Please see the paragraphs below..

Usually every batsman moves the bat (or the body for that matter) based on the bowler action. So when the bowler releases the ball , batsman expects a certain trajectory in his mind for the cricket ball. But in the case of swing bowling, the ball deviates from the actual trajectory. By the time ball started deviating from the actual trajectory , it might have already traveled more than half the way, which will make every batsman bard to respond to the ball's sideways movement. Worst is the case of late swing as well as reverse swing as the batsman may not get time at all to respond.

The bottom line is : If any Cricket batsman fall under the trap of good late swing or reverse swing bowling, there is no point in blaming him, as god had created every human being with this lacuna..

Hope the matter is clear or lets discuss it here..
