 Examples of ball tampering would include a fielder applying a substance, such as lip balm or sweetened saliva, to shine one side of the ball or pick the seam of the ball to encourage more swing.Conversely, roughening one side of the ball by use of an abrasive or cutting surface (such as boot spikes or bottle caps or sandpaper) is also ball tampering.Using spit and/or sweat is common and, for practitioners of swing bowling, integral.
