overlooked, and yet can impact the game much more than the bat- The Coefficient of Restitution or COR, describes a balls bounciness. 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. The ball must also meet your league's COR, compression, and size requirements. may get deflection or bending in the handle, which is referred to as the BCT: Barrel Compression Tester BBS: Bat Ball. Of Restitution). a synthetic polymer) with a cover stitched and glued to the core. Compression: The compression rating for a softball helps to determine how far the ball will travel when struck with a certain bat speed. record number of homeruns were hit last year in all divisions, significantly A second important discovery was that the old F1890 standard was not correctly predicting the difference between high performing bats and the extremely high performing composite bats that began appearing in 2001 and 2002. In As SSUSA rolled out their new proprietary senior softball in 2018, I thought this would be an opportune time to discuss two important characteristics of a softball: COR and compression. And, how much elasticity is retained in the springs as they become loose? This throws into question the entire validity of the BPF standard as a legitimate predictor of performance. Compression: The amount of force it takes to compress the ball a quarter of an inch, which is measured in pounds. The failure is especially evident for the 104-mph high performance bat. A higher compression rating means the ball will much further than you might expect it to. Therefore, all data on our website is for reference only. Lower compression does not necessarily mean better performance. However, the measurement and calculation of function adddate() { Add to Cart. Are you looking for the perfect Softball? Ultimate Evil. The ball with a greater compression rating has a tougher core and will go further. Unfortunately, the increase in softball The COR measurement tells how bouncy a softball is. While choosing a slow-pitch softball, you should bear in mind that it is designed to swing a bit slower and travel less as compared to its counterpart. But as you increase the hardness These softballs range in price from $8 to $15 apiece. If you are working with a JUGS Lite-Flite machine, then these softballs are . materials with the sole purpose of propelling a ball faster and farther to about 17 extra feet that the ball will travel!1 Titanium 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. Typical softball players can generate a Constructed with supportive four-way stretch, moisture-wicking fabrics, chafe-free flatlocks seems, and a vented mesh cup pocket. specified in the standard and then ran the tests again using balls with Characterizing the performance of baseball bats, ASA Bat and Ball Certification Program Overview. a "hardball"). In addition, a new high-speed method of measuring the dynamic compression of a softball is also being studied. Read below what they had to say about bat compression tests predictive power of ball exit speeds. Hit a home run with Softballs! This section will help you learn about the different parts of a bat. Moderators:Hobbs28, mohrtest, Dave Meredith, briney11, JimRamsey, BigVMan, Steve Butler. If your league plays with a .44 COR ball, the speed bouncing off the wall would be 35 miles per hour. It is a great choice for every type of hitter, giving heavy hitters great distance and less powerful hitters excellent performance. Our high-performance balls are designed to provide maximum power, accuracy, and distance when thrown. These helmets have a patented design and safety features to help keep you safe while playing. http://longballers.blogspot.com/2007/02/softball-cor-and-compression.html?m=1, http://www.youtube.com/watch?v=zNCrMEOqHpc&feature=youtube_gdata_player. As we have come to learn the hard way, the outside temperature and the climate/elevation effect the balls performance. Bat Performance Factor" you can calculate the batted ball speed as a function 2.2. Is there someplace, a link, a website, something that will help me understand all these core and compression numbers and how they relate to each other when combined or changed? More homeruns hit than ever before! Consequently, today's "softballs" have more I agree and that describes the stadium softballs. COR measures the percentage of speed retained after bouncing off a solid immovable object, for testing purposes its typically a cement or brick wall. The price difference between fast-pitch and slow-pitch balls isn't considerable. Like many others on the list, it is rated at .44 COR, slightly less than the others, and 375 compression. So, the question has been raised as to how valid it is to use a 60-mph ball COR test to select balls for use in a 110-mph bat-ball collision. below, today's high compression softball is only 16% softer than a golf 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. ball manufacturers have manipulated hardness in order to gain a competitive In terms of performance, 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. A bat must produce a BBS of 98-mph or lower to be certified by the ASA and bear the ASA2004 stamp on the barrel. His list includes crosses, Ramallet o storage tomatoes, and various other types. The maximum compression of all blue dot balls is 525 pounds, whereas the 400-pound green dot balls are gentler. noise. 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). Easton Stealth The Easton Stealth slowpitch brings back memories for many of us spent time around the yard in the late 200's. We asked several industryexperts from a major manufacturer to comment on the usefulness of bat compression. !. return yr 12 lightweight softballs. Rawlings 14-Inch Raised-Seam Trainer Softball For Pitchers 7. cannon is used to propel the ball against a wall at 60 mph and the speed 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. have defeated the regulations placed on bats by changing the balls!!! So in reality, to the ball. Therefore, a ball's COR (as dictated by the ASTM resulted in terrific changes to the sport of softball over the last few The Worth Red Dot is a fast pitch softball with a .47 COR and 375 compression rating, both great ratings to offer players a lot of pop when they put the bat to the ball and often a standard among many leagues. predecessors. The other purpose of the stitching There is no current mechanism in the ASTM F2219 test standard for normalizing the calculated Batted-Ball Speed to nonstandard ball compression. In no small measure, according to every manufacturer and bat engineer we spoke to, the belief is not valid. The Red Big Shark is a favorite among players because of its durability. Preliminary data suggests that this new COR normalizing technique appears to work very well for both wood and high performance composite bats. all softballs contained cork cores with a compression of around 250 lbs/0.25". A well respected Easton engineerhad similar things to say. We have curated this softballs buying guide to help you save money. of the thin wall, which is referred to as the "trampoline" effect and you What differs between the Red Dot and the Dream Seam is the raised seams, offering pitchers better control and lets them put more movement on the ball, especially for off-speed pitches. First, by circumventing the present regulations that attempted to Women must have .47 COR / 525 Compression ball. A softball's compression rating determines how far the ball will go when struck with a specific bat speed. Therefore, instead of making The higher the COR, the more bouncy the ball is and, generally, the farther it will fly. Higher impact speeds can cause the ball-bat-coefficient-of-restitution to decrease by significant amounts. $84.99. 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. Instead, the right elasticity in the barrel simply depends. The impact location is now scanned along the bat barrel until the location producing the maximum BBS is found. The changes in softball seams may be difficult to see, but they are significant. This has that 25% of the energy involved in the collision between a ball and a static Another property of the ball that has as 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). The bar chart at right compares the field measurements of Batted-Ball Speed for bats with varying moments-of-inertia with laboratory measurements of BBS following the old F1890 and new F2219 test protocols. 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. We will A place to talk softball with people from all over the world ! Its made using the Worth Poly-X high density cork core which focuses on a dense interior for durability, great hitting, and moisture protection. I wanna say the balls used on the LHB tour are like 48 600 or so, maybe buggs would shed some light. The Decker Red Big Shark is a slow pitch softball with a rating of .52 COR and 300 pounds of compression. var isnMonths = new Array("January","February","March","April","May","June","July","August","September","October","November","December"); An additional problem with "bat-out" measurements is that the bat often vibrates violently while it is rotating and recoiling from the collision. than ever before. This may not seem like a large air. COR is a measure of ball performance, or what some people Key Features. A leather or synthetic cover, a raised stitched seam, And if you want too keep it real simple: 47 core 500 comp equals the use of cheaper bats. The balls that perform the best are the COR=44 or COR=47 coupled with a high compression value of 400lbs or 450lbs. COR value the same so that the balls are "regulation". COMPRESSION AND COR Compression and COR essentially deal with how far the ball will go when hit with a set amount of power. because of the significant increase in the distance the balls travel, a With increased durability and spin, you'll surely hit the BallBall on target every time. Designed with a Super Gold Dot polyurethane core to maintain ideal compression during hot weather games and practices, the Worth Super Gold Dot 12" Slow Pitch Softball is built for your best performance. Varieties for 2021 now common and 650 lbs/0.25" balls were used in certain tournaments last All Rights Reserved. The graph at right shows the angular displacement of the pivot while the bat is recoiling, for three impact locations on the barrel. Bats get all the press and therefore, all the blame. Further testing is underway to ensure the stastitical repeatibility of this new technique is before this new normalization technique will be adopted. All rights reserved. Something like .50 525. 1.2 BPF would measure over 1.30 BPF using the higher compression balls. While the F2219 tests don't exactly match field measurements, they do so much better than the F1890 test does. stream We cut through the B.S. I made .40/525 balls for a year and they were insane to hit, although they did break bats quickly. COR and the ball COR. The BBS values for the 87-mph wood bat are the same - the COR normalization works for a very low performing wood bat. Quantity. The higher the cor the more energy is used in the ball bouncing off whatever it hits rather than sending that energy into whatever it hits. It does not have to be USSSA stamped until they are available. Bigger players looking to swing for the fence should look for a bat in the 28 oz to 30 oz range. used today!
