Pitching is one of the key elements of baseball, and there are a multitude of rules that go into regulating what a pitcher does on the field. Read on to learn about the rules of pitching and how they impact a game of baseball.

Pitching Rules

Pitching is what gets the action started on any baseball diamond. It may look easy, but it’s much more than just having a catch. It’s a complex throw that takes a lot of practice to get right. Oftentimes, you’ll see more than one pitcher come to the mound in one game, as teams often have over ten pitchers on their roster. It involves speed, accuracy, and knowing the batter at the plate. It also comes with quite a few rules, and we’ll walk you through them below.

All pitches start on the mound, from the pitching rubber or strip. You’ll often see a pitcher pick one leg up, step forward, and release the ball. The other leg, called the pivot foot, must stay on the pitching rubber as the ball is thrown in order for the pitch to be considered legal.

Pitchers can’t take a running start, and every pitch is certain to be coming from the same distance.Pitchers are allowed to step off of the rubber to take signs from the catcher but must have their hands at their sides while doing this.

Balk

When runners are on base, there are a few things pitchers can’t do, and those illegal actions are known as balks.For example, the pitcher can’t fake a pitch or a throw to a base to try to confuse a runner. This is so pitchers can’t purposefully deceive runners. In the case of a balk called by an umpire, the ball is dead, and each runner gets to advance one base. This includes runners on third, who would get to cross home plate and score a run.

Pitchers must make their actions known; they must step toward the base they plan to throw to and must be facing the batter when pitching. Pitchers can’t let the ball drop out of their glove, remove their hand from the ball once set in place, or fake a throw when they don’t have the ball. Ambidextrous pitchers must make it known which hand they’re pitching with.

Throwing Motions

There are only two pitching positions allowed in a regulation baseball game that can be used interchangeably: windup position and set position.From these positions, pitchers are allowed to make any natural motion to get the ball over the plate.

Windup Position

A pitcher in windup position will start with both hands in front, one foot on the pitching rubber and the other foot free.In this position, the pitcher will face the batter, take a step with the free foot, and then throw the ball without interruption. The free foot can be either in front of, behind, or next to the pitching rubber. From this position, a pitcher canthrow to a base, pitch to the batter, or walk off of the mound. This is most often used when there are no runners on base, as it takes longer.

During the throwing motion, the pitcher will start standing straight up and wind up by bringing the ball over their head and stepping to the side, kicking their leg up, and then throwing the pitch. This wind up gives a pitch more power.

Set Position

Also known as the stretch, a pitcher in set position will start with both hands in front, with one foot on the pitching rubber and the other forward.In this position, the pitcher has to come to a complete stop when set if runners are on base. This means that they can move around and stretch before getting set, but they must stop once in this position and then throw the ball.

The set position gives the pitcher a bit of a head start. Unlike the windup, they have one foot forward, kick that front leg up, take a step, and throw the ball. From this position, a pitcher canthrow to a base, pitch to the batter, or step backward and walk off of the mound. This technique is typically used when there are runners on base, as it’s quicker.

Warming Up

Pitchers have their own designated time to warm up before a game. Pitchers have a bit over two minutes to throw as many warmup pitches as they’d like once they get to the mound in Major League Baseball. Pitchers can warm up at the start of each inning, and relief pitchers coming into the game can get their own set of warm up pitches when they enter the game.

Relief pitchers use the bullpen area on the field to warm up before they take the field, and starting pitchers will warm up in the same area before the start of a game. Warming up is important, as entering a game cold can affect velocity and accuracy while also increasing a pitcher’s risk of suffering an injury.

Delays

Pitchers start the action in the game, and nothing can happen if the ball isn’t pitched. With this in mind, if a pitcher had an endless amount of time to throw the ball, baseball games could take all day, which is why there are rules around delays.

When there is no one on the bases, pitchers only have 15 seconds between getting the ball and pitching it.If a pitcher takes longer than the allotted 15 seconds, a ball is added to the batter’s count. The batter must be in the box and ready to hit for these 15 seconds to start. Pitchers also can’t delay the game by throwing the ball to fielders when the batter is at the plate.

When there are runners on base, the pitch clock is slightly longer, at 18 seconds.

Mound Visits

Managers and coaches are allowed to stop the game to come to the mound and talk to a pitcher during the game; this is called a mound visit. This is only allowed once per inning for each pitcher. Each team is allowed five visits each for nine innings, not including pitcher changes. In the case of extra innings, teams can have one visit per inning. If there are two mound visits for one pitcher, that pitcher must be taken out of the game.

The umpire must allow this mound time. Once allowed, the visit is limited to 30 seconds. Players leaving their positions to talk to the pitcher or the pitcher leaving the mound to talk to players also count as visits. Breaking these rules can lead to removal from the game.
