If a player can bowl above 85mph – or if the ball has aged – this
makes it possible for the bowler to “reverse swing” the ball. In simple
terms this is exactly what happens – a delivery that is expected to
swing away from the batter (an outswinger), instead swings in towards
them (an inswinger) – and vice versa. This happens when the seam is
angled for conventional swing but this time the rough side faces the
batsman. If the ball is bowled fast enough (above 85 mph), the laminar
layer goes into a turbulent state before it reaches the seam. The seam
actually has a negative effect here and affects the turbulent layer so
it separates earlier compared with the bottom surface.
Like in conventional swing, there is a lateral force created because
of the pressure difference but this time the lateral force acts in the
opposite (reversed) direction. As mentioned, there is a critical speed
to help generate reverse swing but in cases where this speed can’t be
reached, the roughness of the ball can help reduce this critical speed
needed to create this reverse swing.
As the ball gets older (which means the surface is rougher) it
becomes easier to deliver balls with reverse swing. The fact that more
roughness makes it easier to create reverse swing introduces the
temptation for players to increase this roughness illegally and thereby
make it easier to generate reverse swing at lower speeds.
Hello people, I have been very bust, I was not able to update the app for quite a few months now or answer any of your questions. I apologize for that. I have updated the app few days ago, the update is live on Play Store. I promise to work more hard on the app and give regular updated from now on. UPDATE THE APP
In normal one day cricket (not in the power plays), bowl to hit your length for the first four balls of each over. Build up pressure early in the over, the batter wants to score, so you don’t let him score for the first part of the over. The wicket taking ball ( the variation ) is typically the 5th ball of the over, if you don’t take a wicket with the 5th ball you bowl a ‘dot’ ball ( hit your optimal length ) again on the sixth ball so that the batter is kept at that end to hold the pressure on the batting team and hand it over to the bowler from the other end. Variation for the 5th ball … Width in the crease: You can either go slightly wider in the crease and aim to bowl a full length for the batter to drive, caught at slip, gully or cover if he chases the ball and plays away from his body. Even more potent if you can swing the ball away. You can bowl an off cutter, like a fast off spinner, outside off stump to spin back and hit off or middle stump … or he mistime...
Yorker ke liye bahut practice karni padti hai. pehle apni line or length sudharo. Pehle showmotion me balling karke dekho, apni video banao bowling karte samay fir us video me dekho aap ka runup, action kaise hai apni galtiya sudharo. Fir pace pe kaam karo. Yorker daalne ka tareeka Knowledge Zone me hai. Aap ye video bhi dekh sakte ho. VIDEO
