Simple baseball field
"A baseball field, also called a ball field or a baseball diamond, is the field upon which the game of baseball is played. The term is also used as a metonym for baseball park. ...
The starting point for much of the action on the field is home plate, which is a five-sided slab of whitened rubber, 17-inches square with two of the corners removed so that one edge is 17 inches long, two adjacent sides are 8½ inches and the remaining two sides are 12 inches and set at an angle to make a point. Adjacent to each of the two parallel 8½-inch sides is a batter's box. The point of home plate where the two 12-inch sides meet at right angles, is at one corner of a ninety-foot square. The other three corners of the square, in counterclockwise order from home plate, are called first base, second base, and third base. Three canvas bags fifteen inches (38 cm) square mark the three bases. These three bags along with home plate form the four bases at the corners of the infield." [Baseball field. Wikipedia]
