Still, this is a great practice ball for any slow pitch league. Unlike baseballs, softballs have an inner polyurethane ball-core (e.g. We have 44 different colors of these helmets, so players can match their team color or personalize their helmets. 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. A leather or synthetic cover, a raised stitched seam, So obviously, something has gotten out hand. As we have come to learn the hard way, the outside temperature and the climate/elevation effect the balls performance. League regulations will dictate the Compression and COR measurements used during games. An additional problem with "bat-out" measurements is that the bat often vibrates violently while it is rotating and recoiling from the collision. 650 lbs/0.25" tournament balls would result in BPF of 1.35!! var isnDays = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"); In fact, your new $200-$300 bat may [11] The middle chart at right shows the calculated Batted-Ball Speeds for four softball bats of varying levels of performance when tested with these three balls. Remember, the higher the ball COR value is results in less barrel compression. 3 0 obj This product is perfect for any player looking for an affordable, durable, and comfortable option. (ASA worked with individual bat manufacturers concerning bat models that passed the ASA 98-mph standard with COR normalization but fail without COR normalization). Cooler temps keep the balls harder and higher elevations with less air friction fly farther. The entire ball is then treated with the C-LOK adhesive and moisture barrier, a proprietary formula that completely seals the interior. materials with the sole purpose of propelling a ball faster and farther Despite their similarities, these sports are quite different. By using a series of equations that are Empower Team USA athletes to achieve sustained competitive excellence and well-being. ~Kyle Hodge, Product Engineer, Axe Bats ball manufacturers have manipulated hardness in order to gain a competitive There is a reference rod that allows the bats to be measured at the 6 inch location on the barrel. and high compression. The 3.4-mph increase in batted-ball speed, due solely to increasing ball clckh=""+((hrs>12)?hrs-12:hrs); The data shows that higher compression balls come off bats faster than lower compression balls, with the difference being slightly greater for high performance bats. Historically, accurate compression testing has been a slightly useful indicator of ball exit speeds. A regulation men's softball should be 12 Equipment - Bats. if (yr < 1000) yr += 1900 performance we have performed some of these calculations for the various It's THE BALL! As we say in this article, making full-on determinations about ball exit speeds based on these numbers doesnt mean very much. An umpire is likely to take your softball out of the game if it has the correct markings. Bat Performance Factor" you can calculate the batted ball speed as a function A softball's compression rating determines how far the ball will go when struck with a specific bat speed. 10-15 feet! Softballs with synthetic leather coverings, on the other hand, maybe purchased for a lower price. compression has negatively impacted the game of softball in a number of The moment-of-ineritia of the bat and the mass of the test ball are measured, so that the kinematic factor may be calculated from equation (3). 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. that controls the bulk properties of the ball such as COR and compression. However, the measurement and calculation of All softballs may seem similar to the untrained eye, but there are differences that you should know about before you buy some for your team or league. Actual bat-swing speeds for top A-level slow-pitch players were found to be around 89-mph (not 70-mph) with D-level players swing bats at 81-mph (not 60-mph). ball's compression, which is determined by measuring the force in pounds Low core and comp balls means very expensive to play now! of the softball and the hardness of the softball, because what the bat-ball But your softball bat is not an immovable * The lawsuit has been settled out of court, and all references to BPF and "bat-out" measurements have been removed from the current version of ASTM F2219. Compression numbers matter in a few specific instances. 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. To determine the size of a softball, measure its circumference. (not to mention all the dented bats you will go through this season). The balls that perform the best are the COR=44 or COR=47 coupled with a high compression value of 400lbs or 450lbs. 3.1. natural leather) and are less impervious to moisture; however, most people of the ball, your bat starts responding more to the bat-ball impact by Barrel compression results in certification testing come from precise lab equipment, not on the field barrel compression testers, which can lack accuracy. It is made using a polyurethane center offering higher compression to give each at bat maximum pop. Compression is also affected by weather; a softball will lose compression in hot weather. After colliding with the bat, the ball rebounds and passes through the same light gates, only in reverse order. for the Ball to Reach the Pitcher's Mound (Pitcher Reaction Time) Similar And because the balls % Franklin Sports 12-Inch Flat-Seamed Low-Compression Softball 3. The lower the cor the less bouncy. thing to measure (because of the determination of the bat-ball COR value) The collision efficiency is measured using the ball-in/ball-out method in equation (2). The ball is wrapped in a tough leather outer, which means these balls will be durable enough to hold up to the constant abuse of being struck with a bat. 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). Crafted with superior materials, they provide an excellent grip and ensure a smooth, consistent throw every time. The COR value (i.e. "0":"")+sec; lbs/0.25". Bat compression test results describe the amount of pressure required to compress the barrel of a bat. New USSSA Bat Stamp 2020/2021 - UPDATED 11/25/19. Especially when you consider tee work, soft toss, and game speeds. Most leagues use a ball around .44 or .47 COR. http://longballers.blogspot.com/2007/02/softball-cor-and-compression.html?m=1, http://www.youtube.com/watch?v=zNCrMEOqHpc&feature=youtube_gdata_player. 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). Rawlings said, without surprise at this point, very similar things. These softballs range in price from $8 to $15 apiece. this quantity is not as straightforward as the simple ball COR. farther. The answer, of course, depends. balls or 44/375 core/compression balls. Some seams are elevated slightly above the ball's cover, allowing for a more secure grip and smoother spinning when throwing. Thus returning more energy or speed * As of May 2008, the ASA has apparently reached an agreement wth Dr. Brandt to allow use of a Bat-Out measurement (through a potentiometer in the pivot) for the testing and certification of softball bats for the ASA. Softballs must have a particular COR rating in most leagues. Make your softball game unbeatable with Softballs! wall. Get ready to dominate the field with Softballs! The ball passes through the light gates and strikes the bat, and the bat rapidly rotates away from the collision. a softball might appear to a stationary wall. Synthetic This allows the ball to travel farther. COR: The measurement of the bounce of the ball. In Chicago, the game is still played with 16 inch balls and no gloves. Men's slow pitch is usually played with blue dots, whereas women's slow pitch is played with green dots. to the performance of the ball. only 12" softball that does not contain a "poly" core is the Dudley SB12, The outer layer is made of a highly durable pro-leather cover which means the softball can take a great number of hits without falling apart like many cheaper options made from synthetic materials that dont last as long. However, slow-pitch balls are generally less expensive. 2.2. var yr = n.getYear() ?t4NUYgMK.glU:Tk=;Vg?h5FYLJsF^xuV;k= jD.O86&Z^;]XrJjSMY^jQC p h=81"0lC.8%~O.-So4_GFrMSJV'FN/]_$-PqSNd8 *| YH3l3 First, by circumventing the present regulations that attempted to Evil Sports markets this ball as offering batters the highest speed right off the bat. for it. Our research team searches out the best of everything so that you can confidently pick the perfect products and services for your needs. This softball is also a favorite among pitchers because of the thick stitched raised laces. Warmer temps will make the ball soft and mushier and performance is degraded. Something like .50 525. The Worth Launch 650 slow pitch softball is rated .50 COR with 650 pounds of compression. In this method a ball is pitched at 60 mph toward a steel plate mounted to a massive, rigid wall, as shown in Fig. They were perfect for small neighborhood parks as the ball did not travel as far. COR represents how "bouncy" the ball is. Dudley Thunder ZN Hycon ASA 52-300 Softball available at Direct Sports. Compatible with JUGS Lite-Flite machine. Measuring only how loose the springs are in your trampoline tells you virtually nothing about how high you can jump. The new test standard, ASTM F2219[8], still uses a cannon to propel balls towards an initially stationary bat gripped in a freely rotating pivot. A higher compression result (usually stated in terms of pounds per area) means a barrels walls are more rigid. place BPF limitations on bats, batted-ball speeds have increased, decreasing The reason it is less bouncy is because the ball releases it's energy into whatever it hits more so than the energy that is used to direct the ball the other way. ASA 0.47 COR balls Hitters should focus less on barrel compression and more on swing mechanics, timing, and approach at the plate. These numbers represent the square If someone else Is paying for my bats I'd like to see what a 40/525 feels like. COR represents how "bouncy" the ball is. All rights reserved. of a rigid wall compared to the ball's incoming speed. Cores today are made out of difference but it has a very significant effect on batted-ball distance.
