Description

Baseballs are 9 inches in circumference and weigh 5 ounces. Some baseballs designed for young players may be smaller and lighter.

Baseballs typically have either leather or synthetic covers that are glued to the windings and stitched together. The more expensive the ball, generally the better the cover and the process used to bond the cover to the windings.
Leather covers are the traditional choice because they offer the best grip. Leather covers have consistent performance, durability, and shape maintenance. However leather covers will get dark with use. They will absorb water and get slippery when wet. Usually, the more expensive the ball, the higher the grade of the leather. Synthetic covers are usually vinyl and less expensive than leather covers. Synthetic covers vary in texture and grip depending on the quality. The high quality synthetic covers have a grip and feel that is close to leather. Synthetic covers resist dirt, maintain color well, and do not absorb water. However, like leather covered baseballs, they get slippery when wet. |

Baseballs covers are stitched together to in such a manner to form raised seams, rolled or standard seams, or flat seams.
Raised seam baseballs have the highest seams are typically used by age groups where pitching is being developed. Use typically starts with 8 or 9 year olds up and goes through 14 year old leagues. Raised seams grip the air well and offer the most control for developing pitchers. Fielders can also benefit by enabling a better grip on the ball. Raised seam baseballs are not well suited for machine pitch use. Standard or rolled seams are not as pronounced as raised seams. They are sometimes referred to as major league seams because these are the seams used on Major League Baseballs. Standard seams are used by all age levels and can be used in many pitching machines. Flat seam baseballs are rarely used in game play unless mandated by a specific league. Flat seam baseballs are ideal for use with pitching machines when neither pitching machine balls |

Baseballs are traditionally constructed with wool or cotton thread wound tightly around a center core, although, some low end baseballs do not have windings but only have a solid composite cork and rubber center. The windings and core are the key to the performance and durability of a baseball.
Usually tournament grade and higher baseballs have cushioned cork cores. Cushioned cork cores consist of a cork ball wrapped in a thin layer of premium rubber. Cushioned cork cores are the most dense and have the highest performance. Lower quality balls have cores made of either solid rubber or a composite of ground cork and rubber. Wool or wool blend windings are the most common. Wool windings have the highest compression and shape retention characteristics. The higher the quality of the ball generally the greater the percentage of wool used in the windings and the tighter the thread is wound around the core. Higher quality baseballs retain their shape longer and have higher performance. |

Baseball performance is determined by all the materials and construction used to create the ball. As with most things, the better the components and manufacturing process, the better the baseball performs and the more it costs. With baseballs the key performance measures are how much "pop" the ball has and how long it keeps it, how well the baseball retains its shape, and the grip of the cover.

What's the right baseball for you depends on how the baseball is going to be used. For most people the youth league competition/game grade baseballs are the way to go. They have good performance and durability at a relatively low price and are great for game or practice. If you need something different, then check out the description of the features and the usage chart and pick the ball that best fits your application.

Common Usage
|
|
Official Major League & Minor League Specification Baseballs
|
These are designed as game day baseballs for Major League Baseball or for leagues where the performance of a Major League baseball is required. These baseballs are the top of the line in component and construction quality and have the best overall performance. These balls are designed with wood bats in mind.
|
|
NFHS & NCAA College Baseballs
|
These baseballs are designed for high school and college game play. The general quality of the components and construction is the same as the Major League specification baseballs. However these baseballs are not wound quite as tightly and have a little less "pop" than Major League specification baseballs. These balls are designed with aluminum bats in mind.
Please note that NFHS or NCAA specification baseballs are the same components and construction as the equivalent NFHS or NCAA Approved baseballs, but you must buy the Approved baseball if it is to be used in a NFHS or NCAA game. |
|
Youth League Tournament Grade Baseballs
|
Tournament grade baseballs usually have the same quality leather cover as the high school and college baseballs with wool blend windings with a cushioned cork center core. These balls have less "pop" than the high school and college baseballs, but are considered high performance for youth league baseballs. These baseballs are designed with aluminum bats in mind.
The materials and construction of these balls are the same from one league designation to the next for the same manufacturer. That is the Rawlings RSLL Senior Little League baseball is the ball as the Rawlings RBRO Babe Ruth League baseball, only the league approval stamp is different. |
|
Youth League Competition or Game Grade Baseballs
|
Competition or game grade baseballs usually have the same quality leather cover as the tournament grade baseballs with similar windings and composite cork and rubber or solid rubber center core. These balls have less "pop" than the tournament grade balls and are the most popular youth league baseballs. This is the standard baseball used by most youth leagues. These baseballs are designed with aluminum bats in mind.
The materials and construction of these balls are the same from one league designation to the next for the same manufacturer. That is the Rawlings RSLL1 Senior Little League baseball is the ball as the Rawlings RBRO1 Babe Ruth League baseball, only the league approval stamp is different. |
|
Practice Baseballs
|
Practice baseballs come in both leather and synthetic covers with a variety windings and cores. Practice baseballs are generally less expensive than game grade baseballs and typically don't as much "pop" or as good a cover as a game grade baseball.
|
|
Safety Baseballs
|
Safety baseballs come in a wide variety of covers and performance levels. Safety baseballs are typically for youth players from tee ball up through age 8. They are designed to protect players who are still developing fielding skills.
