You must have come across a ball which has made ur batsman caught behind or by slip as it slicks his bat and u see the radar showing no swing.i'll suggest a method 2 do this. Especially during the new ball session,use the button s.the bowling speed must either be completely full or completely low. Click any direction left or right when the bowler jumps and hold it down.try for an over using same bowler.u'll get that trick for sure. recommended for new ball session only. use specially skilled pace bowlers like Mcgrath,ur created player(100%),harmison, shane bond etc.
