Field setup and care

How to measure the diamond for your age group, prep the dirt, and handle a wet field without damaging it.

Common starting points. Rec leagues change these, especially for 6U and 8U, so check your league's rules. Pitching distance is measured from the back point of home plate to the front edge of the pitching plate.

The red line runs from home plate to second base. The pitching plate sits on that line at your age group's pitching distance, and the 8 ft pitcher's circle is drawn around it.

Placing the bases and pitching plate

  1. Start at the back point of home plate. Every measurement starts there.
  2. First and third base: measure the base path distance to the back outside corner of the base, so the whole base sits in fair territory.
  3. Second base: measure the home-to-second distance from the chart to the center of the base.
  4. Check that it's square: first base to third base should equal the home-to-second distance.
  5. Pitching plate: on the line from home to second, measure from the back point of home to the front edge of the plate. Many fields have more than one plate for different ages, so use the right one.

Double first base: if your field uses one, the white half goes in fair territory for the fielder and the colored half goes in foul territory for the runner.

Prepping the infield

After rain

Is it too wet? If you leave footprints, mud sticks to cleats, or water stands on the infield, it's too wet to drag or play. Playing on a soaked field gets players hurt and damages the field for weeks. Follow your league's and park's rules about closing fields.
