A sports apparatus for monitoring movement of a sport projectile includes a sensor and a wireless interface disposed within the sport projectile for communicating sampled data signals from the sensor, a portable communication device in wireless communication with the wireless sensor for receiving sampled data signals from the wireless sensor, the sampled data signals indicative of a motion of the sport projectile. The portable communication device includes a controller having a memory including programming instructions that when executed by the processor cause the controller to detect a sensor signal from the wireless interface, determine a motion characteristic of the sport projectile from the motion characteristic from the sensor signal, and determine if the motion characteristic is passage of the sports projectile through a goal structure, motion of the sports projectile after a shot or an impact of the sport projectile with an object.
