## What type of thing is baseball?

* Exercise – bodily activity that enhances or maintains physical fitness and overall health or wellness.
* Game – structured activity, usually undertaken for enjoyment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more concerned with the expression of ideas. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional sports).
** Ball game – game played with a ball.
*** Bat-and-ball game – field game played by two teams which alternate between "batting" and "fielding" roles. The fielding team defends, so only the batting team may score, but they have equal chances in both roles.
