The correct answer is: Diamond.

A baseball diamond is the playing field for the sport of baseball. It is a diamond-shaped area with four bases, which are located at the corners of the diamond. The bases are 90 feet apart from each other, and the pitcher’s mound is located in the center of the diamond.

The other options are incorrect because:

  • A court is a playing field for a sport such as tennis or basketball.
  • A ring is a circular area, such as the one used in boxing or wrestling.
  • A pitch is a throw of the ball by the pitcher to the batter.
