In 2018, when SSUSA launched their new senior softball, I saw it as a great chance to talk about two important characteristics of softballs: COR and Compression. One notable difference between the production of softballs and baseballs is their manufacturing process. Softballs have a diameter of approximately 12 inches, a circumference of about 3.8 inches, and a weight of around 7 ounces. They are made up of an inner polyurethane ball-core synthetic polymer, which is then covered with a stitched and glued cover. The cover can be made of leather or a composite material, unlike baseballs.

Softball COR & Compression

Softballs are assessed based on two measurements: COR (Coefficient Of Restitution) and Compression. COR measures the ball’s bounce. A higher COR indicates a more bouncy ball, which generally travels farther. COR represents the percentage of speed reduction for a ball bouncing off a wall. For instance, if a ball is thrown at a wall at 80 miles per hour and bounces off at 40 miles per hour, the speed has decreased significantly, and the ball would be rated with a COR of 0.50. If your association uses a 0.44 COR ball, the speed of bouncing off would be around 35 miles per hour.

Softball compression refers to the hardness of a softball. A higher compression level indicates a harder ball, which typically travels further. Compression is measured by the number of pounds of force required to compress different sides of the ball by a quarter of an inch. If a test shows that it takes 375 pounds of force to compress the ball by a quarter of an inch, the ball is rated as a 375-pound compression ball. The ASA (Amateur Softball Association) has approved two levels of compression – 375 pounds and 525 pounds, with 375-pound balls being softer than 525-pound ones. The ASA rounds up the pressure rating during testing. For instance, if a test shows that it only takes 325 pounds of force to achieve the quarter-inch compression, the ball will be rated as a 375 pressure ball. This means that your association may be playing with a ball rated as 375 pressure, but it is actually softer than a true 375 pressure ball due to the rounding up.

Testing has highlighted two main concerns regarding softball COR, pressure, and on-field performance. Firstly, switching from a .47 COR, 525 compression ball to a .44 COR, 375 compression ball can decrease performance by up to 6%. All other factors being equal, this means that hitting a 305-foot home run using a .47 COR, 525 compression ball would result in a 290-foot fly out using a .44 COR, 375 compression ball. Secondly, reductions in pressure have a significantly greater impact on on-field performance than reductions in COR.

As a player, it’s important to be aware of the impact of weather on the pressure of a softball. Research has revealed that at 100 degrees, a regular softball loses 200 pounds of pressure compared to a similar softball at 60 degrees. This means that a softball rated as a 525-pound pressure ball at 60 degrees may perform like a 375-pound ball at 100 degrees. Additionally, clouds, rain, and humidity also affect ball pressure. At 70 degrees and sunny, balls have lower pressure than if it were 70 degrees and cloudy. Leather balls tend to absorb more moisture in wet conditions than synthetic balls. This usually increases the pressure and level of play to some extent, but once the ball becomes too heavy from absorbing too much water, performance will decrease.

How to Hit a 52 300 Softball

The question of how to hit 52 300 softballs has been a popular topic in the baseball world in recent years. Softball is a popular variation of baseball, and the Allen Sports Association League (ASA) is one of the most well-known softball leagues. Previously, the league used softballs with a .44 COR and 375 compressions, but in the fall of 2012, the rules were modified to allow the use of the new 52 300 softballs. This change had a significant impact on the ASA circuit, raising the important question of how to hit these softballs out of the park.

The newer 52 300 softball is a more exciting version compared to its predecessor. With a higher core value, it has increased elasticity and bounce, resulting in greater speed upon impact with a solid surface. The ASA League modified its standards to align with those of the USSSA League, which included changes to the testing and use of bats and balls. The goal was to make the ball more flexible than the bat, allowing for newer bats and batting techniques to be introduced. These changes brought about newer batting technology and tactics, resulting in an overall different league experience. Many agree that these changes have made ASA bats more effective, leading to more home runs. However, some wise advice on how to hit that 52 300 softball out of the park is always helpful.

In softball, the key element to hitting the ball further is bat speed. The power of your swing does not determine the distance of the ball, but rather the speed of your swing. By increasing your swing speed, you can significantly increase the distance of your hits. Look for bats that are lightweight, aerodynamic, and offer minimal resistance, enabling you to have a lightning-fast swing. With such a bat, hitting the .52/300 ball for miles will be a piece of cake.

When swinging, keep your wrists free and free and your shoulders lose. Anticipate the ball’s appearance and afterward dispatch a swing, not from your lower back, but rather from your hips. This will give your swing the greatest energy for an expanded bat speed. Having an abundant hitting zone with an enormous perfect balance is an incredible advantage of the bat. Concerning hitting the 52 300 softballs, getting stature can be troublesome. To overcome this problem, hitting the ball with a slight uppercut can result in a powerful hit. The 2016 DeMarini Flipper OG, DeMarini Juggy OG, Louisville Slugger Super Z4000, and Easton Salvo are among the best ASA fastpitch bats available this year. These lightweight bats have minimal resistance for maximum swing speed and also feature large handles to provide extra power in swings.

 

Light and quick a thing to take care of when it’s with regards to how to hit the 52 300 softballs. Since the time the ASA League changed its guidelines to utilize the 52 300 balls, hitting grand slams has been on everyone’s psyches. These anxious balls do a ton of the work, thus with the right bats and the appropriate strategy, you can undoubtedly let fly on one of these softballs. As any great hitter will tell you, you need to coordinate with your swing’s pace and timing to get the best hit, however, maybe, this is considerably more significant in softball. An appropriately planned hit on the .52/300, with a quick swing energy, will send the ball taking off for a significant distance. Make certain to distinguish the perfect balance of your bat, and attempt to get your contact not long before the ball crosses the home plate. This will give the hit the most power and speed.

Conclusion

One way to address this issue is to hit the ball with a slight uppercut to generate a powerful hit. Some of the top ASA fastpitch bats for this year include the 2016 DeMarini Flipper OG, DeMarini Juggy OG, Louisville Slugger Super Z4000, and Easton Salvo. These bats are lightweight with minimal resistance, allowing for maximum swing speed. Additionally, they come with large handles to provide extra power in swings.

It’s important to understand that the ball’s compression rating is the key factor that determines the performance of senior bats. Additionally, the ball’s bounciness, also known as its Coefficient of Restitution or COR, is equally important. The 52 300 ball is a great match for senior bats since it provides exceptional performance while also prioritizing safety.

Frequently Asked Questions

1. What is the most popular softball size?

The most popular softball size is the 12-inch ball, which is used for both fast-pitch and slow-pitch games. In fast-pitch youth leagues, players typically start using a 12-inch ball around the age of ten. In some co-ed slow-pitch leagues, an 11-inch ball is used when women or girls bat, and a 12-inch ball is used when men or boys bat.

2. What is the hardest core softball?

It is commonly believed that softballs with a COR of 44 or 47 and a compression value of 400lbs or 450lbs perform the best. Softballs with a compression value of 525lbs or higher are rarely used as they are considered too hot for senior bats.
