Point tracking and game analysis in tennis

A tennis analysis system analyzes tennis game play and generates game statistics for one or more players involved in a tennis session including match play. The system involves electronic portable devices that may be in a form of a dampener device. The portable devices can be mounted on tennis rackets for capturing stroke and other game related data during tennis play. Further, supplemental data may also be captured using personal devices such as mobile phones. The data generated by the electronic portable devices and personal devices can be used in combination by the tennis analysis system to perform game analysis.
