This application started from a postulate: observation of baseball games more often accounts for offensive actions (bats and runs between the bases) than defensive actions.

This application allows observation of each player in Defense and Attack:
- on a Quantitative level (the number of actions of each player leading each to a number of stars)
- on the Qualitative level (the success or otherwise of the actions undertaken: coloring of the stars of each player in Green > Blue > Yellow > Red, thus recalling the color code of the skills of the common base).

Additional game rules have been added in defense to respond to an observation on the field: too often team defense relies on the activity of a few players, and some do not move and just look at their teammates.
On each round the team's score includes the points scored in the attacking phase as well as the points scored in the defensive phase: its points correspond to the number of defensive stars of the player with the fewest stars.
The goal is then to make each player responsible for their involvement and to insist the team (and in particular the most influential players in the game) to organize themselves to allow everyone to express themselves in the team.

Finally, a report will allow you to recover all the data from the match.
