Compression is how hard the ball is, it refers to how much force is required to compress the ball 1/4". The only other property that is regulated by the softball associations is the ball COR (which stands for Coefficient Of Restitution). with a static and immovable object. Hit a home run with Softballs! The COR and compression ratings described below are based on the different types of cores. Crafted with superior materials, they provide an excellent grip and ensure a smooth, consistent throw every time. We discussed the topic with every major manufacturer and compiled their sentiment, as we understood it, below. A change from a Cor of .44 to a COR of .47 would result in a 6% performance increase. If a ball is thrown at a wall at 80 miles per hour and bounces off at 40 miles per hour, the speed has been reduced by 50%. Much like the perfectly dialed in trampoline, a bats effectiveness is not always maximized by merely making the barrel walls more flexible. It should make the ball easy to spot and easy to grip. Crafted from premium materials and designed for maximum performance, our softballs are the perfect way to stay on top of your game. Compression measures how many pounds of force is required to squeeze two sides of the softball in by one-quarter of an inch. compression from 350 to 650 lbs/0.25" for a 60 mph swing speed, is equivalent The changes in softball seams may be difficult to see, but they are significant. This means that a softball that is a 525 pound compression ball at 60 degrees may play like a 375 pound ball at 100 degrees. A regulation men's softball should be 12 This gave the materials engineers A softball's cover is made of one of two materials: natural or synthetic leather. in common with a golf ball than they have in common with their earlier polymerization process. Easton Stealth The Easton Stealth slowpitch brings back memories for many of us spent time around the yard in the late 200's. They add how bat compression is done at a field level (with devices like the one you see in the video above) arent reliable. All Rights Reserved. In addition, a new high-speed method of measuring the dynamic compression of a softball is also being studied. years. Note: Dont confuse COR with core which is the center of something, as they sound the same when pronounced. $74.99. bats were banned for increasing batted-ball distance by only about 650 lbs/0.25" tournament balls would result in BPF of 1.35!! These helmets have a patented design and safety features to help keep you safe while playing. A bat with a lower compression means the barrel walls are more flexible or elastic. Low core and comp balls means very expensive to play now! Make your softball game unbeatable with Softballs! However, the Dream Seam can also help players with traditional throwing by offering more control, which can translate to enhanced confidence during each play on the field. the ball, which are discussed in further detail in the main article. Your league might even tell you which dot balls to use, or they may give you COR and compression limits. The Amateur Softball Association began regulating the performance of slow-pitch softball bats in 2000. 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. Features a Core Flex Pocket Design that offers enhanced comfort and range of motion. Softballs have a circumference of ~12 inches and a diameter of ~3.8 inches, and weigh about 7 ounces. Compression is measured, but not used for performance testing certification for a reason. We visit dozens of internet sites and systematically compile the most common comments about each bat. It is a thin-walled flexible tube, designed to return energy as efficiently The outer layer is a ProTac leather cover, a highly durable leather wrapping ensuring the balls will last through multiple batting practices or actual games. As such, measuring pressures at a point of the bat and calling it a performance comparison is not accurate. This is the smallest softball size you'll find. The pressure gauge is then set to zero (USSSA) or 500 (ASA/NCAA). Im probably wrong but I believe cor= the size of the inside core of the ball. 2.2. The Worth Dream Seam is another fast pitch softball with a .47 COR and 375 compression rating. JavaScript is disabled. speed is 30 mph then the COR rating would be 30/60 = 0.50. Remember, the higher the ball COR value is results in less barrel compression. We will ?t4NUYgMK.glU:Tk=;Vg?h5FYLJsF^xuV;k= jD.O86&Z^;]XrJjSMY^jQC p h=81"0lC.8%~O.-So4_GFrMSJV'FN/]_$-PqSNd8 *| YH3l3 specified in the standard and then ran the tests again using balls with have blue stitching and NSA balls have black stitching. 2022 United States Olympic & Paralympic Committee. to the performance of the ball. scrutiny in recent years. Calculated BBS normalized to weight only. If a test shows that it takes 375 pounds, then the ball is rated as 375 pound compression ball. Another property of the ball that has as And a ball with a compression of 535 lbs/0.25" resulted in a BPF Things have obviously gotten out of control. best electric space heaters for large rooms, The Best 44 Cor 375 Compression Softballs of April: Reviews & Buyers Guide, Worth One Nation 12 inch Gold Dot Slowpitch Softball Balls, Dudley12" USASB Thunder Hycon Slowpitch Synthetic Softball, Dudley 12" Thunder ZN Hycon ASA Composite Slowpitch, Half Dozen Evil Ball USSSA 12" Softballs 40 cor 325 Compression MP-Evil-CLAS-Y-2, MacGregor X44RP ASA Slow Pitch Softballs, Yellow, 11-inch (One Dozen), Worth One Nation 12 inch Gold Dot Slowpitch Softball Balls, ON12CY, Dudley12" USASB Thunder Hycon Slowpitch Synthetic Softball - 12 Pack, Dudley 12" Thunder ZN Hycon ASA Composite Slowpitch Softball, Half Dozen Evil Ball USSSA 12" Softballs 40 cor 325 Compression MP-Evil-CLAS-Y-2 Classic M 6 Balls, Dudley 12" USASB Thunder Hycon Leather Slowpitch Softball - 12 Pack, Evil Ball ASA 44-375 HOT Leather Cover 44 core 375 Compression Softball, 12-Inch Comp, Pack of 12, Half Dozen Evil Ball ASA 12" Softballs 44 cor 375 Compression MP-Evil-ASA-Y-2 HOT Technology 6 Balls, Dudley Thunder Advance 12" Slow Pitch Softball - Composite Cover - Pack of 12, The Best Propane Heaters of April: Rankings, Reviews You Should Know About, Top 10 Best Diesel Generator: Top-Rated diesel generator for home use for 2022, Top 10 Best Generator for Camping That Are Surprisingly Quiet and Efficient, The Best Generator For Power Outage on Amazon, Reviews by Experts, Best Inverter Generators List of 2021: Rankings, Comparison & Reviews, The Top Inverter Generator on Amazon, Reviews by Experts, The 9 Best Electric Space Heaters For Large Rooms of April for Every Budget, The Best Buy Open Box Desktop Computers as Reviewed by Experts: Top-picks & Best Deal for you, The 10 Best Home Meat Slicer Top Rated 2021. the time players have to react to the batted ball. No need to settle for anything less than the best - Softballs! Further testing is underway to ensure the stastitical repeatibility of this new technique is before this new normalization technique will be adopted. Slow-pitch softball is more famous for recreational play. However, the hardness "0":"")+min; Cooler temps keep the balls harder and higher elevations with less air friction fly farther. ball manufacturers have manipulated hardness in order to gain a competitive That optimal compression is one factor in ball exit speeds, but far from the same. Consequently, when a ball hits the bat you get deflection your bat stamped 1.2 BPF is really equivalent to about a 1.3 BPF bat because BCT: Barrel Compression Tester BBS: Bat Ball. Get ready to dominate the field with Softballs! Softballs are generally priced between $4 to $10 apiece. as possible. 1.2 BPF would measure over 1.30 BPF using the higher compression balls. Size will depend on the rules of your league. I do believe that the SSUSA STOTE 44Cor/375lbs compression ball, makes for a perfect marriage with our senior bats, allowing for excellent performance as well as safety considerations (please take a look at the photos attached to this article). New USSSA Bat Stamp 2020/2021 - UPDATED 11/25/19. Moderators:Hobbs28, mohrtest, Dave Meredith, briney11, JimRamsey, BigVMan, Steve Butler. Again, just because a softball is labeled "fast-pitch" doesn't mean it will play under your league's rules. But, non-linear designs, standard in performance bats these days, makes compression tests less helpful in predicting exit speeds. Here is a sampling of compression tests we took on bats at Bat Digest. 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). Non Linear Bat Compression Thresholds. Consequently, a very high COR rating will not compress the bat barrel as much, which in turn will not maximize ball-exit-speed and distance. Unfortunately, the website appears to be down and it is unclear if this is temporary or permanent. become illegal in a few years if the ASA adopts its proposed legislation or seam, and the core. Worth. I wanna say the balls used on the LHB tour are like 48 600 or so, maybe buggs would shed some light. Get ready for game day with Softballs! } COR represents how "bouncy" the ball is. Each gate is triggered when the ball breaks the plane of light, and the ball speed is measured as the distance between pairs of light gates divided by the time between trigger signals. Still, this is a great practice ball for any slow pitch league. 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. ways. Evil Sports markets this ball as offering batters the highest speed right off the bat. Compression is also affected by weather; a softball will lose compression in hot weather. Players aged nine and under should use an 11-inch ball because it fits better in their hands. 0.50 and your bat has 1.2 BPF, then the bat-ball COR would be 0.6. return yr a softball at a mounted bat. all softballs contained cork cores with a compression of around 250 lbs/0.25". As a result performance is not degraded nearly as much when playing those hot afternoon games, where other balls seem to go dead. Those factors include, among other things, both the quality and durability of the material. However, because you may use one bat or glove for several seasons or more, and you will likely go through hundreds of softballs in that time, the expense of softballs may rapidly add up. the pivot point of the bat while being swung is on the handle approximately 6-inches from the knob end. Some seams are stitched in red, while others are stitched in blue. Of Restitution). Women must have .47 COR / 525 Compression ball. 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. However, like with other items, softballs have substantial variations that may not be apparent at first look, and those distinctions are crucial. A non-linear bat is a bat whose structure deviates from the traditional single wall, multi-wall and/or layered composite designs. All balls that meet ASA's certifications for championship play can be found by visiting the certified equipment section of asasoftball.com. var dname = isnDays[now.getDay()]; act on a golf ball. Get ready to dominate the diamond with Softballs today! These ratings are typical among ASA rated leagues, offering batters greater distance and pop at each at bat. 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. For a better experience, please enable JavaScript in your browser before proceeding. On the other hand, an official Major League baseball consists of a cushioned cork center, wrapped tightly in several windings of wool and polyester/cotton yarn, and then covered by stitched cowhide. The Worth Hot Dot slow pitch softball is rated at .52 COR with 300 pounds of compression. for injury. The dots on Worth softballs are a visual way to tell how bouncy and hard each ball plays. Richard Brandt, the inventor of the Bat Performance Factor, has patented the "bat-out" technique[10] and subsequently sued the ASA to prevent them from using it to certify bats. 50th Street, Oklahoma City, Oklahoma 73111 email ccress@softball.org, phone (405) 425-3441, fax (405 . Effect of Ball Hardness on BPF, Calculated Batted Ball Speed, and Time This means that a 240-foot out with a .44 COR ball would turn into a 254-foot home run with a .47 COR ball. deforming elastically and returning that elastic energy back to the ball. 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. Each hit will offer players high velocity and a great amount of pop. this quantity is not as straightforward as the simple ball COR. Most bats in a particular classification sit real close to each other on a compression test scale. 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. A standardized method has been developed to measure this property (ASTM F1888). Despite their similarities, these sports are quite different. Women's fastpitch softball is played professionally and is an Olympic and summer sport. natural leather) and are less impervious to moisture; however, most people Compressiondoesnt matter to me; Im hitting bombs either way. Quantity. In other words, the ball manufacturers 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. The COR would be measured at .50. Table 1 is for the same bat, the only thing to change is the ball hardness. Games taking longer to play! stream A leather or synthetic cover, a raised stitched seam, The chart at top right shows the COR, compression, and weight for three softballs. Compression: The amount of force it takes to compress the ball a quarter of an inch, which is measured in pounds. Bat compression test results describe the amount of pressure required to compress the barrel of a bat. Blaming your bat for a bad AB is counter-productive. Cut one open, its the hard center. If your league plays with a .44 COR ball, the speed bouncing off the wall would be 35 miles per hour. Although a 14-inch softball is more of a recreational softball size, it is used in some slow-pitch leagues. Further testing has revealed that the BPF (ratio of Bat-Ball-COR to Ball-COR) is not independent of the COR of the ball. In the mid-1980's they started replacing the cork core with a polyurethane but it represents a simple concept. You must log in or register to reply here. While the F2219 tests don't exactly match field measurements, they do so much better than the F1890 test does. are red stitched and their .50 COR balls have white seams. var month = now.getMonth(); The other purpose of the stitching We may earn a commission if you make a purchase through one of our links. pieces of equipment, (see Figure 1 - Parts of a Softball). Coefficient of Restitution) is how much is given back after the impact with a solid wall during testing. Any user who clicks join from our promotion accomplices that are highlighted on Homechit, we can get a commission according to our partner policies. A softball's compression rating determines how far the ball will go when struck with a specific bat speed. More homeruns hit than ever before! Are you looking for the perfect Softball? and high compression. Just Bat Reviews, LLC DBA Bat Digest Company. The higher the core rating, the more bouncy the ball, which generally correlates to how far it will travel when hit with a bat. of the softball is the solid polymer core. | 12" Poly | ZN Composite, Last update on 2023-04-18 / Affiliate links / Images, Product Titles, and Product Highlights from Amazon Product Advertising API. Slow-pitch softball and fastpitch softball are the two main variants of the sport. Or, as we might say, loosening the springs of the bat. Balls with a certain compression rating are required in most leagues. Synthetic object was lost to inelastic processes such as deformation, heat, and vibrational (more on this in future articles), while softballs have received much less Consequently, today's "softballs" have more COR represents how "bouncy" the ball is. Fermenting is a great way to separate viable from non-viable seeds as only the larger, viable, seeds will sink during rinsing. A wet ball will initially experience an increase in compression, but as more moisture is absorbed, compression will decrease. This ball is made of a high density polyurethane wrapped in a composite material outer with flat seams. COR balls, regardless of association, have gold stitching. So obviously, something has gotten out hand. This solid core determines the bulk properties of Its made using the Worth Poly-X high density cork core which focuses on a dense interior for durability, great hitting, and moisture protection. The more significant problem for the ASA is that the COR normalizing technique in F2219 was overcompensating for high performance bats. The maximum compression of all blue dot balls is 525 pounds, whereas the 400-pound green dot balls are gentler. Google searches can provide inform. Available in both 11 and 12 inch sizes. Some seams are elevated slightly above the ball's cover, allowing for a more secure grip and smoother spinning when throwing. Its made using a synthetic "super grip" outer cover which can take the constant batting of games and practice. Including bat materials, overall . The bat is gripped at the 6-inch point on the handle in a pivot that is free to rotate after the ball hits the bat. compression balls using the respective BPF values measured and assuming 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. sec=today.getSeconds(); Slow-pitch softball leagues generally utilize 12 softballs that move slower and further than fast-pitch softballs. COR essentially measures is the so-called trampoline and springboard effects. Dudley Thunder ZN Hycon ASA 52-300 Softball available at Direct Sports. The 3.4-mph increase in batted-ball speed, due solely to increasing ball the effect that ball hardness has on the performance of a bat. The most common COR ratings for That equation, based on factors like the jumpers weight and leg strength, as well as the quality of the springs recoil, would set the optimal amount of taut in the tramps springs. If this data extrapolates linearly, then the high-compression Approved for: ASA, USA Softball Design: Two piece composite Barrel length: 13.5 inches Weight drop: 34/25, 34/26, 34/27 MSRP: $229.95 5. 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. Higher C0R has more elasticity and less bat damage. Varieties for 2021 Cruz Captain lucky/v, This website uses cookies for functionality, analytics and advertising purposes as described in our, Explanation on Softball cor & compression. energy to the ball by making the bat-ball collision more efficient. I made .40/525 balls for a year and they were insane to hit, although they did break bats quickly. "springboard" effect. At the moment, however, the question of using a "bat-out" measurement to obtain the collision efficiency for the ASA BBS standard may be somewhat of a moot point. have defeated the regulations placed on bats by changing the balls!!! the ball used for testing must have a compression of 350-375 lbs/0.25" TheyOTE="TWmccoy, post: 18863474, member: 829"]I still think the best flying balls are high cor. Definition: Ball compression rating describes the stiffness or hardness of the ball, Coefficient of Restitution or COR, describes the bounciness of the ball. Some believe that a more elastic barrel wall can produce faster exit speeds. It is a ratio between the bat-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.
