CoverSports teaches you how to measure & lay out a baseball field. Home plate to first base — Measure from the back white part of home plate to the 99 feet; Home plate to front of pitching rubber — 50 feet; Infield arc radius — 65 feet .
Repeat this process starting from the second post, making sure the second string or tape is the same length as the first. Next, measure and locate the center of the backstop. Extend a straight line from this point out to where the arcs intersect. Position the apex of home plate on this line, and depending on which type of field, a prescribed distance from the backstop. Recommended distance from backstop to apex: Locate Second Base Run a line from the center point on the backstop, through the apex and over pitcher's mound to place second base on center.
The distance to measure is from the apex of home plate to the center of second base. Distance from apex to center of second base: Locate First Base and Third Base Measure the appropriate baseline distance to third base from the apex and scribe an arc. Measure the same distance from the center of second base to third base and scribe another arc. Place the outside back corner of the base where the arcs intersect. Repeat to locate first base. At the Rogers Centrethere are no foul poles, but large nets suspended from the roof that serve the same purpose.
At Petco Parkthere is no foul pole in left field; the pole's function is served by a yellow metal strip along the corner of the Western Metal Supply Co. Pitcher's mound[ edit ] The pitcher moves forward off the rubber as the pitch is released.
In roughly the middle of the square, equidistant between first and third base, and a few feet closer to home plate than to second base, is a low artificial hill called the pitcher's mound. This is where the pitcher stands when throwing the pitch. Atop the mound is a white rubber slab, called the pitcher's plate or pitcher's rubber.
This peculiar distance was set by the rule makers innot due to a clerical or surveying error as popular myth has it, but intentionally further details under History. In Major League Baseballa regulation mound is 18 feet 5.
A pitcher will push off the rubber with his foot in order to gain velocity toward home plate when pitching.

In addition, a higher mound generally favors the pitcher. With the height advantage, the pitcher gains more leverage and can put more downward velocity on the ball, making it more difficult for the batter to strike the ball squarely with the bat. The lowering of the mound in was intended to "increase the batting" once again, as pitching had become increasingly dominant, reaching its peak the prior year; is known among baseball historians as "The Year of the Pitcher.
A pitcher's mound is difficult for groundskeepers to maintain. Usually before every game it is watered down to keep the dust from spreading. On youth and amateur baseball fields, the mound may be much different from the rule book definition due to erosion and repair attempts.

Even in the major leagues, each mound gains its own character, as pitchers are allowed to kick away pieces of dirt in their way, thereby sculpting the mound a bit to their preference. The pitcher may keep a rosin bag on the rear of the mound to dry off his hands.
Major League Baseball teams are also permitted cleat cleaners on the back of the mound. This may be a flat grate-style plate, or simply a hand tool such as a piece of wood used to remove mud and dirt from cleats. These items are allowed to remain on the backside of the mound at the discretion of the umpirethus reducing the probability that they will affect a live play.
Baselines are not drawn on the field, although the foul lines serve to mark the baseline between home plate and first base, and between third base and home.
Running baseline[ edit ] Generally, base runners are not required to follow the baseline. A base runner seeking to advance more than one base typically "rounds" the base, following a more circular path.
However, a base runner's left-right motion is constrained when the defense tries to tag him. At the moment the defense begins the attempt, the baserunner's running baseline is established as a direct line from his current position to the base he is trying for. Running lane[ edit ] Beginning halfway between home and first base, and ending at first base, there is a second chalk line to the right of the foul line.
This second line and the part of the foul line it runs parallel to, form the running lane that defines the path in which a batter-runner must run as he is advancing to first base.
First base itself is not located in the running lane, but Rule 6. Humphrey Metrodomeshowing a white "grass" line. The grass line, where the dirt of the infield ends and the grass of the outfield begins, has no special significance to the rules of the game, but it can influence the outcome of a game. Dirt running paths between the bases and, at one time and still in some parks, between the pitcher and the catcher have existed since the beginning of the game, although they were not mentioned in the rule books until aroundand their specifications are flexible.
In addition to providing a running path, the grass lines act as a visual aid so that players, umpires and fans may better judge distance from the center of the diamond. Occasionally the ball may take a tricky bounce off the dirt area or the edge between the dirt and the grass.
Multiple World Series championships includingand have been decided or heavily influenced by erratic hops of ground balls. In artificial turf stadiums, infield dirt was originally only placed around the bases and around the pitcher's and batting areas, which are referred to as "sliding pits.
Among Major League Baseball fields, Rogers Centre was the last stadium to maintain this type of configuration and was reconfigured with a full dirt infield starting in the MLB season. Outfield[ edit ] The outfield is made from thick grass or artificial turf.
It is where the outfielders play. The positions to play in the outfield are right, center, and left field named in relation to the batter's position; thus left field is beyond third base and right field is beyond first base.What "The Bases" Really Mean
Outfields vary in size and shape depending on the overall size and shape of the playing field. The outfield stretches from the infield to the outfield wall and it contains the warning track. Outfields especially vary from Little League to Major League fields. Little League outfields vary more in size than Major League outfields. Outfields often differ from infields in the specific type of grass used, but most Major League outfields are grass. Because the warning track's color and feel differ from the grass field, a fielder can remain focused on a fly ball near the fence and measure his proximity to the fence while attempting to catch the ball safely.
A warning track's width is not specified in the rules. It is generally designed to give about three steps of warning to the highest-level players using the field. Typical widths run from about six feet for Little League fields to about 10—15 feet 3.
A warning track this wide also lets groundskeepers avoid driving maintenance vehicles on the grass.

The track can be composed of finely ground rock particles such as cinders, which is why announcer Bob Wolff called it the "cinder path" rather than the "warning track. When ballpark designers saw how the track helped fielders, it soon became a feature of every ballpark.
Single-minded fielders often crash into a wall trying to make a catch despite the warning track. For this reason, outfield walls are typically padded for extra safety.
Wrigley Field 's brick wall is covered only by ivy, which is not especially soft. However, there are pads on the walls of the tight left and right field corners in foul ground. Warning-track power is a derogatory term for a batter who seems to have just enough power to hit the ball to the warning track for an out, but not enough to hit a home run. The term more generally refers to someone or something that is almost but not quite good enough for something.
Outfield wall[ edit ] The Green Monster inshowing the manual scoreboard and Green Monster seating, and more recent additions, including charity advertisements along the top, billboards above the Green Monster seating, and the American League East standings. Pitchers warming up in the bullpen The outfield wall or outfield fence is the wall or fence that marks the outer boundary of the outfield.
A ball passing over the wall is dead ; if it passes over the wall in fair territory while in flightit is a home run. As a result, baseball fields can vary greatly along those lines. The wall has numbers affixed or painted on it that denote the distance from that point on the wall to home plate. In most modern major league ballparks, the wall is made of some hard material e. Chain link fencing may also be incorporated into the wall in areas where the wall needs to be transparent, e.
Many ballparks feature a yellow line denoting the top of the wall to aid umpires in judging whether the ball passed over the wall or if the ball is fair or foul. Bullpen The bullpen sometimes referred to as simply "the 'pen" is the area where pitchers warm up before entering a game. Depending on the ballpark, it may be situated in foul territory along the baselines or just beyond the outfield fence.
Relief pitchers usually wait in the bullpen when they have yet to play in a game, rather than in the dugout with the rest of the team. The starting pitcher also makes his final pregame warmups in the bullpen. Managers can call coaches in the bullpen on an in-house telephone from the dugout to tell a certain pitcher to begin his warmup tosses. On-deck There are two on-deck circles in the field, one for each team, positioned in foul ground between home plate and the respective teams' benches.
They are technically known as next-batter's boxes.
