Field Preparation

The purpose of this page is to give you a better understanding of field layout and how to prepare the field to make it a safer place for our youth to play.

You will need the following items which will either be located in the boxes located behind the back stops, and/or the equipment shed located past the outfield of JM2. In general, the home team prepares the field before each game and puts the equipment away after the last game of the day. If a Moraga team is away on CP or JM against a team from another city (e.g. Orinda, Piedmont, etc.), then the Moraga team prepares the field and puts the equipment away afterwards.

TIP: Be certain to get the combination for the shed and lockboxes from your coach and test them before you really need them to work.


  • ATV with Drag
  • Trowel or digging tool (to reveal and open water sources)
  • Water hose with connector to source on one end and sprayer on the other (water boxes are located behind the pitcher's mound)
  • Measuring tape (see field dimensions for distance to pitching mound)
  • Portable pitching mound, if mound is not permanent (Pinto 38' with 9' circle, Mustang 44', Bronco 48', Pony 54')
  • Batter's box template
  • Brush
  • String line
  • Chalk liner and chalk
  • Bases
  • Rake
  • Home run fences (JM1 and JM2)
  • Tamper (optional)


The following is the most popular procedure use to prepare the infield:

  • Clear the infield of everything that is not permanently attached to the infield.
  • Drag the infield with the ATV starting at the outer most area and work your way the pitching area, DO NOT DRAG THE BASE MOUNTS, PITCHING MOUND, OR HOMEPLATE. Use the ATV to pull the drag.
  • Water the entire infield using the hose connected to the valve in the green boxnear the mound and a spray noozle. Start with home plate, then the first and third baselines, so others can start chalking the lines. Spray extra water on the home plate and pitching area, but do not create puddles.
  • Rake the home plate to level depressions created by batters in the boxes and catchers behind the plate. Second and third base may also develop depressions from runners sliding.
  • Use the batter's box template to make an impression of each box by walking on the template. Chalk the boxes. Some find marking all parallel lines first then marking the perpendicular lines easier for the batter's boxes. Beware of soft top soil and wheel impressions.
  • Run the string from home plate down the first then third base lines past the outside edge of the base. Chalk the line from the batter's box to the edge of the grass.
  • Chalk an "on deck" circle outside each dugout approximately one fence post toward home page from the dugout entrance.
  • Rake the pitching areas to cover the water source box. For permanent mounds, spread roughly 1/4" to 1/2" of dirt where the pitcher strides out. For portable mounds, measure the appropriate distance from home plate to the pitching rubber and position the mound. Then, rake dirt under the edges to stabilize the mound, so it does not tip. Slightly cover the front edge of the mound to make a smooth landing area.
  • Brush the dirt off the base mount knobs and secure the bases.
  • (optional) If you would like to chalk base coach boxes, remember the far side of the box starts at the base and lays out towards home plate, if you want to install a running lane, it starts half way down the first base line, is in foul territory, is 3' wide and stops short of first base.
  • JM1 and JM2 have home run fence in the container on a designated shelf. Each fence and shelf is marked with the division name. On weekdays, first game of the day visitor team install the fence and the last game of the day home team put the fence away. On weekends, first game of the day home team install the fence and the last game of the day home team put the fence away.
  • When the last game or practice of the day is over, return everything to either field's lockbox (e.g., bases, hose, etc.) or the container (e.g., ATV, rake, portable pitching mound, etc.). If you are not certain another team is going to use the field later in the day or a lot of time will pass before the next team uses the field, put all of the equipment away. BE CERTAIN TO LOCK THE FIELD'S LOCKBOX AND THE SHED BEFORE LEAVING.
