Make your softball game unbeatable with Softballs! The higher the core rating, the more bouncy the ball, which generally correlates to how far it will travel when hit with a bat. The only other property that is regulated by the softball associations is the ball COR (which stands for Coefficient Of Restitution). Therefore, a ball's COR (as dictated by the ASTM the ball used for testing must have a compression of 350-375 lbs/0.25" COR represents how "bouncy" the ball is. in a 4.8% increase in batted ball speed. This softball is also a favorite among pitchers because of the thick stitched raised laces. Nevertheless, softball associations have The ball would be rated with a COR of .50 (referred to as a fifty COR ball). Ready to take your softball game to the next level? Women's fastpitch softball is played professionally and is an Olympic and summer sport. it doesn't matter whether the cover is synthetic or leather. If someone else Is paying for my bats I'd like to see what a 40/525 feels like. Slow-pitch softball is more famous for recreational play. Most leagues use a ball around .44 or .47 COR. has been rapidly increasing to the point where 500 lbs/0.25" balls are In no small measure, according to every manufacturer and bat engineer we spoke to, the belief is not valid. Therefore, instead of making Compression ratings of 275, 350, 400, or 525 pounds in the softballs are common. Therefore, a COR rating of 0.50 means core (See Figure 1 - parts of A Softball). These women's softball helmets are perfect for the girl who wants to be on the field and in the game! Sometimes this game is so easy. sec=today.getSeconds(); Get ready to play with Softballs by [Brand Name] and experience the difference! But your softball bat is not an immovable It might be made of different materials, including PU leather, cork, rubber. In light of these research findings, the ASTM's Baseball and Softball Equipment subcommittee F08.26 began drafting a new test standard which would more closely represent actual game conditions in the field. Any user who clicks join from our promotion accomplices that are highlighted on Homechit, we can get a commission according to our partner policies. Get ready for game day with Softballs! The outer layer is a unique Syco leather cover, a highly durable pro-leather material so it will the ball will last through every at bat during games and practice. In the first two published versions of the ASTM standard, F2219-02 (2002) and F2219-04 (2004) the calculated BBS was normalized to the COR of a "standard" ball by adjusting the equation used to calcualte the normalized collision efficiency as. Currently, COR is measured as the ratio of ball-out to ball-in speeds when a ball is fired from a cannon with an initial speed of 60-mph towards a rigid wall. If your league plays with a .44 COR ball, the speed bouncing off the wall would be 35 miles per hour. The softball's core is the part that you never see. 650 lbs/0.25" tournament balls would result in BPF of 1.35!! necessary to deform a softball in compression by 0.25". JavaScript is disabled. become illegal in a few years if the ASA adopts its proposed legislation Most bats in a particular classification sit real close to each other on a compression test scale. Franklin Sports 12-Inch Flat-Seamed Low-Compression Softball 3. "; The Worth Hot Dot slow pitch softball is rated at .52 COR with 300 pounds of compression. Get ready to hit it out of the park with Softballs! This throws into question the entire validity of the BPF standard as a legitimate predictor of performance. The 3.4-mph increase in batted-ball speed, due solely to increasing ball Youll get more results if you spell it cor. of a rigid wall compared to the ball's incoming speed. only about half as far when batted. The Easton Stealth The Easton Stealth slowpitch brings back memories for many of us spent time around the yard in the late 200's. Data shows that the relative speed between bat and ball has a very large effect on the resulting elastic properties of the collision. Equipment - Balls. The ASA website maintains current listing of bats which are legal for ASA play, as well as list of bats which are banned form ASA play. The reason the Evil BP Rockets work so well is by using a higher C0R we can raise the compression a bit and have a ball thats a blast to hit without killing bats. The dynamic relationship between the bat and ball is more complicated than the stiffness of the bat in the hoop direction. for the Ball to Reach the Pitcher's Mound (Pitcher Reaction Time) Thus every bat on the market today would be illegal under these new rules! We paraphrased, as far as we understood it. Definition: Ball compression rating describes the stiffness or hardness of the ball, Coefficient of Restitution or COR, describes the bounciness of the ball. 2021 Homechit.com. They were perfect for small neighborhood parks as the ball did not travel as far. The failure is especially evident for the 104-mph high performance bat. or seam, and the core. Something like .50 525. used today! We also monitor auctions on a daily basis and compute the average selling price of the bats we review assuring you of having the best information when you purchase your bats. 0.50 and your bat has 1.2 BPF, then the bat-ball COR would be 0.6. Discover Tomato Varieties: While Galactic Magic Seeds is No Longer Available, There's Still Plenty of Variety for Your Garden, Galactic Magic Seeds was a website that offered tomato seeds from various breeders, including Rebel Starfighter Prime. Compatible with JUGS Lite-Flite machine. a "hardball"). Baseball and Softball Bat Compression Bat compression can be a useful tool to estimate the performance of a given bat construction, but taking the compression value without reference will rarely provide an accurate measure of actual bat performance. Remember that the ball COR was measured scrutiny in recent years. for it. Ages: Typically 18 and older. However, slow-pitch balls are generally less expensive. It is not known what happened to the breeder of Rebel Starfighter Prime or why Galactic Magic Seeds is no longer available. The measurement of BBCOR was changed from a "bat-out" measurement to a "ball-out" measurement which results in greater accuraccy and less variation in the measured value. pieces of equipment, (see Figure 1 - Parts of a Softball). The entire ball is then treated with the C-LOK adhesive and moisture barrier, a proprietary formula that completely seals the interior. It has been explained to me a couple of times. According to the ASTM F2219 test protocol, a softball (with tight restrictions on weight, COR and compression) is fired from a cannon at 110mph towards a stationary bat. No matter what temperature or weather conditions, the Decker Red Big Shark was made to last, withstanding hot heat and humid temperatures while delivering great pop to players at bat. By For example, a ball of yarn looks the same to your bat as This value indicates how much energy is left over after the ball strikes the immovable object and then bouncing back at a speed lesser than its incoming speed. Moderators:Hobbs28, mohrtest, Dave Meredith, briney11, JimRamsey, BigVMan, Steve Butler. var year = getFullYear(now); act on a golf ball. lbs/0.25". air. This is the smallest softball size you'll find. The ball gives players lasting performance giving players great at bats. From these Softballs by [Brand Name] are the ideal match for your team. A softball's compression rating determines how far the ball will go when struck with a specific bat speed. The impact location is now scanned along the bat barrel until the location producing the maximum BBS is found. stream tests a ball with a compression of 425 lbs/0.25" increased the BPF measurement Something like .50 525. Incoming pitch speeds matter when considering the optimal barrel compression. 2022 United States Olympic & Paralympic Committee. There are only three parts to a softball: the cover, the stitching And because the balls You have no idea how much I love that commercial. (not to mention all the dented bats you will go through this season). But that is no longer the compression value for balls Bat compression test results describe the amount of pressure required to compress the barrel of a bat. Further testing is underway to ensure the stastitical repeatibility of this new technique is before this new normalization technique will be adopted. You end up with a ball that doesn't FEEL super hard off the bat, but retains quite a bit of elasticity in the core. However, it should be mentioned that some players report the covering began to wear and/or unravel early. ball hardness starting in 1999 [ASA of the type of balls used today. var day = now.getDate(); Brian Duryea 50th Street, Oklahoma City, Oklahoma 73111 email ccress@softball.org, phone (405) 425-3441, fax (405 . 3 0 obj of the softball is the solid polymer core. In the current landscape of many associations/leagues, there seems to be a misconception that bat compression is the end-all, be-all of performance. Champro CSB83 11in. Unlike baseballs, softballs have an inner polyurethane ball-core (e.g. And what they mean when combined with different bats. Unfortunately, the website appears to be down and it is unclear if this is temporary or permanent. Compression: The compression rating for a softball helps to determine how far the ball will travel when struck with a certain bat speed. If your league plays with a .44 COR ball, the speed bouncing off the wall would be 35 miles per hour. Each hit will offer players high velocity and a great amount of pop. BBS: Bat Ball Speed (98 mph is the maximum bat ball speed allowed for a bat to be USA Softball Certified), Click here for the Non-Linear Bat Compression Thresholds PDF(as of 2/27/2023), Bat Tester Information can be found at www.barrelcompression.com. Then, equation (4) is rearranged in order to calculate the BBCOR in terms of the measured collision efficiency (as a ratio of ball speeds) and kinematic factor: During the 2002 ASA National Tournament in Montgomery, AL, an extensive field study[4,5] of bat swing speed and bat performance was conducted. Certain softball leagues and game types use a 16-inch ball. These ratings are typical among ASA rated leagues, offering batters greater distance and pop at each at bat. $74.99. The market has dried up for these high exitspeed balls with the notable exception of the Long-Haul Bombers Home Run derby competitions or local home run derbies, where distance is the goal. Its hard to find softballs today that are 525lbs compression or higher as they are found to be too hot for our senior bats. Women's fastpitch softball is played professionally and featured at the Summer Olympics, but slow-pitch softball is more prevalent among casual players. Much like the Worth Red Dot, which is a favorite among many players, the Dream Seam also has a Poly-X high density cork core using proprietary dense cell formulation, which ensures a dense interior for great hitting and high durability. However, it must be from a USSSA licensed manufacturer. << /Filter /FlateDecode /Length 2570 >> Compression= how tightly the string in the ball is wound. I'll try to relay what I was told. Most models come in 26 oz., 27 oz., 28 oz., and 30 oz. However, the COR normalization does not work as well for the other three bats. %PDF-1.3 Preliminary data suggests that this new COR normalizing technique appears to work very well for both wood and high performance composite bats. ways. Initial ball speed was increased from 60-mph to 110-mph in order to provide a more realistic relative speed between bat and ball (25 + 85 = 110). A much more robust COR normalizing technique (also more mathematically complicated) has been proposed and is being considered by the ASTM F08.26 Baseball and Softball Equipment committee for inclusion in a future update of the F2219 test standard. Add to Cart. USSSA has decided to move back the legal use to give players a longer usable period for currently . It is made using a polyurethane center offering higher compression to give each at bat maximum pop. 2.1. function adddate() { I still think the best flying balls are high cor. as possible. ball hardness to the level prescribed in the original BPF testing requirements, Balls are often sold by the dozen or by the bucket. I made .40/525 balls for a year and they were insane to hit, although they did break bats quickly. Varieties for 2021 Once you know what ball you need for your team or league, go online and look for the best prices. A reading of "bat-out" speed may be obtained from the output of a potentiometer in the pivot mechanism. Sorry about any spelling errors. Three speed readings are possible (between the first pair, second pair and first-third pair) and these readings provide the ball-in speed measurement. Rawlings 14-Inch Raised-Seam Trainer Softball For Pitchers 7. The quality raised laces give pitchers more grip for pitches that involve less speed and more control and movement, while offering non-pitchers better control during throwing. The ball passes through the light gates and strikes the bat, and the bat rapidly rotates away from the collision. object was lost to inelastic processes such as deformation, heat, and vibrational typical bat-swing speeds for adult slow-pitch players are around 60-mph, with some top level players cabable of reaching 70-mph swing speeds. VIERA, FL (October 30, 2019) The current approved 1.20 "Thumbprint" stamp for USSSA Slowpitch Softball bats will NOW be LEGAL for USSSA play Indefinitely (Previously until January 1, 2023). As well, quick and accessible compression measurements, made possible by field-level compressors, lack the precision required to make direct correlations to ball exit speeds. It's hard to find softballs today that are 525lbs compression or higher as they are found to be too hot for our senior bats. are red stitched and their .50 COR balls have white seams. causing a tighter network. The compression is the same for all three balls (452lb) and the COR is nearly the same (0.46), but the weights are significantly different (6.43oz, 6.78oz, and 7.04oz). That optimal compression is one factor in ball exit speeds, but far from the same. the BPF rating of a bat. compression. The Worth Launch 650 slow pitch softball is rated .50 COR with 650 pounds of compression. A bat with a lower compression means the barrel walls are more flexible or elastic. to 1.26. Finally, However, a couple of researchers are investigating a new method of measuring a dynamic compression by measuring the force and contact time during a higher speed collision between a ball and a cylindrically shaped rigid surface. With its all-weather design, you'll be able to practice and play all year round. Fastpitch softball players will often use an 11-inch ball. ( Read more), Package dimensions :36.83 cm x 27.94 cm x 10.16 cm, Steady compression in both high and low temperatures, Lower compression design results in less damage to bats, Synthetic cover provides a nice feel and aesthetic appeal, plays the same in cold weather as it does in hot weather, Leather cover provides improved grip and protection, Evil Ball 12 inch ASA 44 core 375 compression, Patented Multi-Layer Core Center Techonology, Thunder ZN - Pro M Stamp | .44 COR | 375 lbs. the time players have to react to the batted ball. In fact, your new $200-$300 bat may Researchers are also looking into improving the way that ball COR is measured. Im probably wrong but I believe cor= the size of the inside core of the ball. Copyright 2023 Bestcovery.com, LLC. This makes absolutely no sense. Softballs are rated based on two metrics - Coefficient Of Restitution (COR - pronounced like core) and compression. } The higher the compression, the harder the ball and the farther the ball will sail into the big blue sky when hit. may get deflection or bending in the handle, which is referred to as the The COR measurement tells how bouncy a softball is. The diameter of a softball is between 11.88 and 12.13 inches, and its weight is between 6.25 and 7.00 ounces, while the diameter of a baseball is between 9.0 and 9.25 inches, and its weight is between 5.0 and 5.2 ounces. In the mid-1980's they started replacing the cork core with a polyurethane You may save anything from a few cents and a $1 for each ball. As we have demonstrated above, all bats that are today stamped You can see this list on our ball exit speed spreadsheet too. var isnMonths = new Array("January","February","March","April","May","June","July","August","September","October","November","December"); COMPRESSION AND COR Compression and COR essentially deal with how far the ball will go when hit with a set amount of power. This year, many gardeners are looking for new varieties of tomatoes to try out in their gardens. There is no current mechanism in the ASTM F2219 test standard for normalizing the calculated Batted-Ball Speed to nonstandard ball compression. Compression is how hard the ball is, it refers to how much force is required to compress the ball 1/4". COR = Coefficient Of Restitution. Because of the variations in hitting, throwing, and field distance, softball is unquestionably more difficult than baseball. The LA Times editorial staff was not involved in the creation of this content. The most popular softball size for both fast-pitch and slow-pitch games is 12 inches. something to manipulate. Plentiful data exists showing that ball COR decreases as ball speed increases. If the rebound are highly engineered "tools" made out of sophisticated lightweight structural The last measurement to be concerned with is compression. by injection molding. Your league might even tell you which dot balls to use, or they may give you COR and compression limits. Last year, ASA approved the 52/300 ball for SP play. Rawlings said, without surprise at this point, very similar things. prefer the "feel" of leather. The 12-inch blue dot ball is larger than the 11-inch green dot ball. These higher compression balls Some seams are elevated slightly above the ball's cover, allowing for a more secure grip and smoother spinning when throwing. referred to as a bat-ball COR, which is a measurement of the Coefficient Purchasing softballs by the dozen is the most cost-effective option. Our high-quality helmets come with adjustable chin and head straps for the perfect fit, even when things heat up on the diamond. As such, measuring pressures at a point of the bat and calling it a performance comparison is not accurate. The outer layer is made of a highly durable pro-leather cover, which translates to a more durable softball that can take a great number of hits without falling apart. Bat Performance Factor" you can calculate the batted ball speed as a function 2.2. Softballs have a circumference of ~12 inches and a diameter of ~3.8 inches, and weigh about 7 ounces. performance we have performed some of these calculations for the various The ratio of ball-out to ball-in speeds determines the collision efficiency or BESR. 1.2 BPF would measure over 1.30 BPF using the higher compression balls. Barrel compression results in certification testing come from precise lab equipment, not on the field barrel compression testers, which can lack accuracy. clckm=((min<10)? Size will depend on the rules of your league. The bar chart at left showed that the old F1890 was not accurately predicting field performance, and the bar chart at right shows that F1890 was severely underestimating the performance of the high performing metal and very high performing composite bats being used in games and tournaments. Compressiondoesnt matter to me; Im hitting bombs either way. by shooting the softball at an immovable object, usually a 2" thick steel We may earn a commission if you make a purchase through one of our links. The purpose of the cover is to appeal to the senses. balls or 44/375 core/compression balls. $84.99. Instead, the location of maximum BBS tends to vary from bat to bat. The speed of the softball depends on the compression as well as COR ratings. Several research labs are attempting to collect and correlate data for this new measurement technique, and once the results are verified a new ASTM standard may be written for dynamic compression. But, the following changes and improvements were made: Based on the data from this "era" study, the ASA chose to set the maximum BBS value, effective January 2004, to be 98-mph. typical pitched-ball speeds for the game of slow-pitch softball are around 10-mph. However, the hardness To ensure success, select medium-sized seeds for planting. Finally, 0.44 The higher the COR, the more bouncy the ball is and, generally, the farther it will fly. But as you increase the hardness Men's slow pitch is usually played with blue dots, whereas women's slow pitch is played with green dots. The ball would be rated with a COR of .50 (referred to as a fifty COR ball). a very common and tough polymer known as polyurethane and are produced specified in the standard and then ran the tests again using balls with However, like with other items, softballs have substantial variations that may not be apparent at first look, and those distinctions are crucial. Our new SSUSA STOTE contains a vapor-barrier-lock, which provides for better performance in warmer weather conditions. The ball with a greater compression rating has a tougher core and will go further.
