The Tecumseh baseball program features two baseball fields. The Senior Diamond is a full sized regulation baseball field for the older campers and the all-camp team. The Junior Diamond is scaled down to Little League specifications for the younger campers.

Tecumseh also has a carefully supervised baseball batting cage where players can regularly practice their batting technique. The pitching machine can be programmed to pitch at various speeds to suit the level of the batter. The machine can also be programmed to pitch curve balls.

Each year, the Tecumseh baseball staff includes college or high school baseball coaches as well as current college or high school players.

Both fields are in regular use. Many in-camp games are played and games against other camps are scheduled each year.
