The Journey of a Baseball: From the Factory to the Field

Have you ever wondered how many baseballs are used in a single game? The answer varies depending on the level of play, ranging from high school to the Major Leagues.

In this article, we will delve into the world of baseballs and how they are used in different games and seasons.

MLB Games

In Major League Baseball (MLB), up to 70 baseballs are used in a single game. Each team brings their own set of baseballs that are approved by the league.

These baseballs are then ready to be used throughout the game, with new balls being introduced after every at-bat lasts a period of seven pitches. Why are baseballs switched out so often?

It is because the balls suffer damage and scuffing during the game, affecting the pitcher’s ability to grip and release the ball consistently. Switching out baseballs ensures that the game is played on a level playing field where no team has an unfair advantage.

Before a game, each baseball is prepared with great care to ensure that they are identical in terms of size, weight, and consistency. All MLB baseballs are made by Rawlings Factory in Costa Rica, where the leather is hand-stitched by 28 skilled craftsmen.

The balls are then rubbed with mud for consistency before being shipped to the teams. To supply baseballs for a single game, a total of 120 brand new baseballs are required, and they can cost up to $6 each.

This makes the cost of supplying baseballs for 15 games set to around $10,800.

High School Games

At the high school level, things are a little different. High school teams might not have the same financial power as their MLB counterparts, so they must find creative ways to reduce costs.

One way to do this is to reuse baseballs throughout the season. High school baseballs can cost between $75 and $100 per dozen, so it is essential to find ways to make them last.

Many baseballs are lost out of bounds during games or struck and scuffed, but still serviceable. These used baseballs are then used for practice or lower level games.

Due to the cost of buying new balls, it is important to track the number of baseballs being used to ensure they wont run out during the season. Generally, high school teams need around 30 to 60 balls for their season, and it is highly recommended to buy in bulk, either at the beginning of the year or from a significant supplier.

College Games

College baseballs have a lifespan of just six innings. This is because college games typically last only nine innings, so three baseballs are used in a single game.

The baseballs used in college games are also affected by scuffing and must be replaced frequently. Scuffing is a term used to describe when the ball is damaged or altered on the surface.

There are various types of scuff marks, including scratches or smudges on the ball’s surface, as well as bits of dirt stuck to the leather. These scuffs can significantly affect the pitcher’s ability to grip and release the ball consistently, something positively crucial in baseball.

Because of this, college baseballs can be quite sturdy, made with high-quality materials to withstand the rigors of play. There are official balls specially designed for the College World Series, and these tend to have a more significant degree of compression and other construction aspects designed to increase the ball’s effectiveness.

Minor League Games

In the minor leagues, each team gets 144 baseballs per game, and every ball is brand new. This quantity is set to ensure that there are enough baseballs to set aside for batting practices before and during the game.

Such practices are vital to sharpen the players’ skills and techniques. Triple-A games and higher typically use special baseballs that have been treated with a pre-game rubbing mud, which helps pitchers grip the ball better.

The rubbing mud comes from a small town in southern New Jersey and has been used in Major League Baseball for over 70 years.


Asides from games, there are also practices to consider, which can amount to a considerable sum. It is important for teams to have a supply of baseballs to facilitate these practices.

The number of baseballs used per season can differ based on the team’s practice schedule. However, most teams use approximately 12 to 144 new baseballs per season, depending on the number of practice sessions scheduled.

Playoffs are also a critical event where teams need fresh new baseballs without any scuffs. The Major League Baseball playoffs alone require over 7,000 baseballs in total, with over 100 being used in a single game.

The balls used for these games are usually special, with the playoffs’ logo and date printed on them.


In conclusion, depending on the league being played, the number of baseballs used per game, practice schedules, and the importance of commercially available baseballs, the numbers of baseballs can vary and are vital to the sport’s functioning. And while there is no specific guideline on how much baseballs each game should need, the number of balls used is determined by factors as scuffs, grip, consistency, and cost.

So when next you are watching a baseball game, you may want to ask yourself just how many balls were used and the journey to get them to the game. 3)

High School Games

High school baseball is a significant part of American culture, and while it’s not as glorified or grand as college or professional ball, it remains an essential component of the sport at large.

At this level of play, games are not as competitive as in college or MLB, although they are challenging in their way. With that said, high school baseball matches certainly call for high-quality tools and equipment.

But how many baseballs are used in a single game, and why is that number so few? High school baseball games typically use only a few baseballs.

Since schools are passionate about keeping costs down, they depend on fewer baseballs, and the recycled ones from games are used for practice. Typically, high school teams use between 3 to 5 dozen baseballs per season, with each match using about 6 to 10 baseballs.

It is also worth noting that high schools often spend less money on baseballs than their college or pro counterparts, which tends to be between $75 to $100 for a dozen balls. There are various reasons why fewer baseballs get used in high school games.

One reason is that these matches separate teams by experience level, which means that there may be skill gaps between the two teams. Coupled with the lack of force coming at the ball, fewer baseballs are needed for a high school game.

Playing baseball in high school can also be a way for students to hone their skills, learn teamwork, and play sports on a socially competitive level without taking it too seriously. At this age, it’s about the experience, and playing the game requires fewer baseballs, which keeps the cost down, making it more accessible to all students.

That said, the National Federation of State High Schools Association (NFHS), which is responsible for setting guidelines for high school sports across the country, has its guideline for how many baseballs should be used in a game. According to the NFHS, a minimum of a dozen baseballs is required to begin each match, with more available if necessary.

The guideline ensures that there are enough baseballs if a ball gets lost, thrown out of bounds, or hit and scuffed, and that the game can continue without delays, simultaneously keeping the cost down. 4)

College Games

College baseball games are similar to their professional counterparts, with a more competitive edge, more spectators, and the objective of ranking well in their division.

How many baseballs are used in a single game, and why is the number here set at a much higher number than high school games? In College baseball games, 60-65 new baseballs are used per game, replacing them after six innings, to ensure that the balls are consistent, and to give the umpire a fresh set of balls to use when needed.

The college ball game is fast-paced and requires a high level of expertise, with a lot of force coming at each ball. The ball’s consistency throughout the game is vital, and replacing them ensures that the pitcher can adequately grip the ball.

Before a game, each baseball is prepared with great care to ensure that they are identical in size, weight, and consistency. College baseballs use a specific gripping mud to rub the ball’s surface, making the surface a little rougher and increasing gripping consistency.

Mud is a popular alternative way to rough up the surface of the ball rather than using pine tar, but it only serves a specific purpose. Pine tar can also be quite messy and disgusting to work with, especially if it gets on a coachs hands.

Mud comes in from Oil City, NJ, every year called Lena Blackburne Rubbing Mud, and it washes off easily. The mud’s consistency is so essential that baseball teams have entire jobs and positions dedicated to ensuring the balls have the right amount and are correctly rubbed down.

The College World Series (CWS) is an annual baseball tournament held in Omaha, Nebraska. The CWS leading up to a final, there are typically between 30-50 dozen baseballs used since each match needs a fresh set of new balls.

During the final, there can be as many as five dozen new baseballs used – just in case the game goes on for longer than the nine innings.


In conclusion, the number of baseballs used in a game depends on the level of play. High school games use fewer baseballs compared to college or the professional level because matches are less intense and more focused on experience than winning.

Colleges and professional levels require more baseballs to accommodate the faster pace, the game’s competitiveness, and consistency. However, the one constant in all types of baseball games is that each baseball is treated with great care and precision.

Every ball is crucial to a match and every effort is made to ensure that they maintain the correct size, weight, and consistency throughout the game. 5)

Minor League Games

Minor league baseball provides an opportunity for aspiring professional baseball players to hone their skills and compete at a higher level than high school or college.

At this level, teams typically use more baseballs compared to high school teams, but less compared to their MLB counterparts. In Minor League Baseball games, the number of baseballs used differs depending on the league level, with double-A games using 50 to 60 baseballs, single-A games using 40 to 50 baseballs, while triple-A games using up to 100 baseballs per game.

The reason for these differences is that triple-A games are more heavily attended and, as a result, need more baseballs to accommodate quick ball retrieval in case of foul balls or homers hitting over the fence.

The baseballs used in Minor League are the same as those used in MLB, which means that each baseball is made to the same specifications, is leather with a cork and rubber core.

Baseballs used in minor league games tend to be sturdier than those used in MLB since teams have to get the most out of each ball and often use them for practice after minor league games. In terms of scuffing and dirt, these baseballs are typically used until they cannot perform effectively anymore.

This practice does create a mixed bag of balls that can lead to unpredictable plays. It also makes it challenging for the pitchers to grip the ball consistently due to dirt and scuff marks on the surface.

6) MLB


Major League Baseball is America’s national pastime and an exceedingly profitable industry. With that large size comes high costs due to the number of staff, players, and support staff needed to ensure everything is in place for every game, and this includes the supply of baseballs.

During the season, a staggering 291,600 baseballs are used in MLB games, and each ball costs around $6. These baseballs are made of top-notch quality materials that can withstand the forces generated by professional players.

Replacing baseballs frequently during a game is imperative because if the ball has visible scuffs, the pitcher can quickly work out what type of pitch they will throw next, leading to an unfair advantage. Fresh baseballs guarantee consistent play for all players.

In 2019, the cost of supplying baseballs for an entire MLB season would have been around $1,749,600, a substantial amount. However, the cost of baseballs is a minor expense compared to other operational costs faced by organizations, particularly given the significant revenue generated by the league.

Baseball is one of America’s most treasured and enduring sports. Its an industry that has evolved from a humble pastime to sophisticated and lucrative, with professionalism and consistency as integral elements of the sport.

And while the cost of playing baseball continues to increase, one thing remains the same the importance and quality of the baseball. In conclusion, the number of baseballs used per game differs based on the level of play, and each level has different regulations.

Baseballs are essential to the sport, and each ball is carefully crafted to be consistent with its weight and size. The cost of baseballs is also a crucial aspect, with high school games using fewer balls, while MLB games use a significant amount.

One takeaway from this is the importance of consistency throughout a game and how keeping costs down can be a consideration for lower levels of play.
