Stall Angle
A contact angle for a rubber in which the speed and/or spin of the rubber is reduced dramatically. The stall angle can be used effectively for certain shots such as no-spin serves and loops. However, when a rubber has a wide band of stall angles it can contribute to a lack of control as the player may not be able to choose when the phenomenon will occur.
A stall can also occur if a mismatched blade is used with a rubber, and also at a particular contact angle when the racket contact speed is too fast.
