why does college baseball use aluminum bats and not wooden

If major league baseball players used them we’d just be watching a game full of home runs. Aluminum bats were introduced long before modern sponsorships; they were legalized because of the sharply rising costs of wooden bats. The horizontal axis (Impact Speed) represents the swing speed of the bat. Sci. Penna, "Batting performance of wood and metal baseball bats," Med. Data was collected for each player until 30 line drives were produced within a certain range of locations in the outfield. They found that the width of the sweet spot was nearly the same for all bats (wood and metal) bats tested. [10] All other bat parameters being equal, the bat with the lowest hoop frequency will have the highest performance. Can the Los Angeles Dodgers repeat in 2021? [8] G.S. 48, 505-510, (1977). Aluminum. One memorable example happened during 2000 World Series between the New York Yankees and the New York Mets. All of these games are now affected by how much money the player/team has to spend on all this technology. 12-17 (2003) Chicago, IL. Clemens picked up the broken bat and threw it towards Piazza as he ran towards first. Many people have argured that the fact that aluminum bats don't break has a noticeable impact on the game of baseball. In comparison to the metal bats used today, Valesente said the quality of the Worth bats was not up to par. Well, now you know why professional baseball players use wooden bats instead of aluminum bats! They are starting to band aluminum bats so I can't answer your question. [5] R.M. The issue is … baseball - is curt schilling's politics keeping him out of the hall of fame? The answer is that aluminum bats are banned in the professional league because aluminum bats are easier to use. The batted-ball speeds measured in the Crisco-Greenwald study are significantly higher than batted-ball speeds obainted with bats which currently pass the NCAA performance standards. Originally, it was because aluminum bats last a lot longer. Many new rules and regulations in college baseball dictate the materials permitted in college baseball bats. Because the barrel of an aluminum bat is hollow, the distribution of mass along the length of a metal bat is considerably different than it is for a solid wood bat. Figure 4. Thus baseball programs get but a pittance, and cannot afford to splurge on wooden bats, which break, and must go with aluminum, which do not. This is why most college teams switched to aluminum in the early 1980s, because wood bats would break a lot, high quality wood was harder to find, and so wood bats became more expensive. Do the Detroit Tigers have the best front office in basball and can it be believed? Krahenbuhl, and P. Lu, "Dynamic and performance characteristics of baseball bats," Research Quarterly, Aluminum bats can also be made lighter than wooden bats. Instead I would like to look at the physics of baseball bats and investigate the scientific data to support the claim that metal bats perform better than wood bats. The first aluminum bats were heavy and did not perform much differently than wood bats. The location on the bat where an impact results in the least sting is not always the same as the location where the ball comes off the bat the fastest. While aluminum bats are common from little league to college baseball, MLB remains steadfast in its use of wooden bats. [4] J.J. Crisco and R.W. Most college teams can get by with 12 aluminum bats per season, as opposed to more than 5 dozen wood bats per season. There was already some bad feelings between the two players because Clemens had hit Piazza with an inside pitch the previous year, and the broken bat incident only increased the animosity between the two players. Sports Exerc., 34(10), 1675-1684 (2002) The physics behind the trampoline effect is somewhat complex, though a simple model can be used to illustrate the main concepts, as explained elsewhere on this website. Baseball trajectories and final distances for various batted ball speeds, References Then there is performance. Figure 2 compares the balance points of four 30" youth bats: three wood bats of weights 26oz, 23oz, and 20oz, and an 27oz aluminum bat. Russell, " "Hoop frequency as a predictor of performance for softball bats," Engineering of Sport 5, Vol. [1] The study was conducted with six skilled college players during more than a dozen batting practice sessions over a 5-day period. This can be explained if the metal bat has a trampoline effect which returns more of the energy to the ball. [5,6] Their study involved actual players swinging bats at pitched balls in a batting cage. While watching ESPN Sports Center one night towards the end of May 2003, I saw a clip from a college game in which a metal bat shattered leaving the batter holding the handle and half the barrel while the other half of the barrel flew out and landed next to the shortstop. Many of the marketing ploys regarding the size of the sweet spot often refer to the perception that a given bat is more forgiving (ie., balls still go far, and bat feels good) for impacts away from the sweet spot. The solid curve is a theoretical prediction from my simple mass-spring model of the trampoline effect, and the data points represent the measured BBCOR values (extracted from the original field study data by my friend and colleague Alan Nathan) for the five metal bats used in the Grisco-Greenwald batting cage study. I support the movement to ban aluminum bats from all leagues, just to keep the kids safer. Figure 3 compares batted ball speeds for balls hit with a wood bat (orange dots) and the highest performing metal bat (blue dots) used in their study. Crisco and Greenwald defined the sweet spot as the range of locations on the bat barrel for which the highest 10% of batted ball speeds were obtained. Therefore, BBCOR bats with lighter barrels do not equal wood in some batting scenarios, they have LESS pop. That’s due to one major factor—the weight of the barrel is heavier in wood bats. Biomech., 17, 241-252 (2001). Wood bats have been a big part of my baseball life. Again, the only published study todate which offers evidence of an enhancement in performance for metal bats due to an elastic property of the bat is the Crisco-Greenwald study. Messier, B.S. They are pretty fun to hit with and i believe it makes for a more exciting baseball game. The NCAA is the highest level of amateur baseball where regulations allow players to hit with aluminum bats. [9] J.J. Crisco and R.W. When a ball hits a wood bat, it compresses to nearly half its original diameter, losing up to 75% of its initial energy to internal friction forces during this compression. It is not, however, impossible for aluminum bats to break - but usually when they do it is not the handle but the barrel that breaks. The plot in Fig. Aluminum is much stronger than ash wood, and the handle of an aluminum bat is a thin cylindrical tube with reasonably thick walls (thicker than the barrel portion). Where as an aluminum bat can last the entire season. 641-647 (International Sports Engineering Association, 2004). Piazza's bat broke and the barrel portion bounced out towards Clemens on the mound. [4] But, their data does not show a difference in the size of the sweet spot for wood and aluminum bats. In all three cases the balls left the bat at a height of 2.6 feet above the ground and at an initial angle of 35. [1] F.O. You can sign in to vote the answer. <<>> Major League Baseball players can't use aluminum bats because wooden bats maintain historical continuity, keep offenses reasonable and improve safety for players on the field. MLB Trivia: Two different Indians' pitchers has won the AL Cy Young since 2010. Who are the two pitchers? In contrast the aluminum bat is actually heavier, but since its balance point is more than an inch closer to the handle it will be easier to swing. The results were an average batted ball speed (for line drives) of 88.6 mph for the wood bat and 92.5 mph for the aluminum bat. The bats used in this study were manufactured before the NCAA implemented its current performance limits which restrict the performance of an aluminum bat through (i) the "minus-3" Length-weight rule, (ii) the BESR test (ball exit speed ratio), and (iii) the lower limit on moment-of-inertia. Are Baseball fans some of the MEANEST, SNOBBIEST & MOST OBNOXIOUS FANS IN ALL OF SPORTS. It definetly is a money issue, because the aluminum one last longer, while they probably get new bats each season, its better then having to spend for a new batch weekly with wooden breaks. 6 shows ball trajectories for varying batted ball speeds. Disclaimer: While the results were not published in peer-reviewed research journals until 2000-2001, the data for the Crisco-Greenwald batting cage study was collected during 1997-1998. A side effect was that the ball goes a bit further off the aluminum bat than it does the wood. High speed video was used to obtain a 3-D map of the bat swing, locating the trajectory of several points on the bat and ball before, during, and after impact. Batted ball speeds were measured using a radar gun. Not all baseball bats are made the same. Fleisig, N. Zheng, D.F. The data also shows that not all metal bats are the same. Aluminum bats make inside pitches singles and the bats don't break. Crisco & Greenwald were only able to conclude that an "inherent elastic property" of the bat was most likely present to explain the difference in batted- ball speeds shown in Figure 3. Most college and high schools use aluminum bats because they dont break and they are on budgets. Money?? But there's an, ahem, aluminum lining to this story: The process used to manufacture metal bats can be tightly controlled. Personally, I might as well have gone to the plate with a wet sock than a wood bat. [2] In this study balls were shot from a pitching machine towards bats held stationary (without swinging) in the hands of a player. As aluminum alloy gives the bat a lightweight, well-formed, balanced and sturdy structure which is not easily possible in other forms of baseball bats. Only wooden bats are allowed in major league baseball. Wooden bats are heavier and solid, whereas aluminum and titanium bats are much lighter and hollow. The purpose of this document is not to argue for or against aluminum bats. This answer might seem a little obvious, but think about it! If bats were lighter, players would be able to swing with a greater force than they are able to with wooden bats, making it easier for professional players to hit a pitch. http://www.cbsnews.com/stories/2006/07/27/earlysho... Why do people even watch baseball cause let's be honest it has got to be the most boring sport in the world ? Bryant, L.N. But there are options for players to consider based on their bat speed and hand strength. A third study in the early 1990's also concluded that metal bats performed no better than wood bats. I measured the frequency of the mode of vibration in the barrel, called the hoop mode, which gives rise to the trampoline effect. Plotting the data this way normalizes the results so as to remove the effect of different moments-of-inertia (see reason [1]). 28-38, (Prentice Hall, 1997) They were not able to explain differences in this effect between the five metal bats they tested, and so could not explain how the trampoline effect improves performance. No bat which currently passes the NCAA performance standards will perform as high as the best metal bats in the Crisco-Greenwald study. [14] Robert K. Adair, The Physics of Baseball, 3rd Ed., (HarperCollins, 2002), Metal baseball bats can outperform wood bats with a similar `sweet spot', Batted Ball Speed as a Function of Swing Speed and Impact Location, "Hoop frequency as a predictor of performance for softball bats, So what does it mean that a player using an aluminum bat can hit a ball 8-mph faster than he could with a wood bat? During the Summer of 2004 I was granted access to the five metal bats used in their batting cage study. Hester and K. Koenig, "Performance measurement of baseball bats," Journal of the Mississippi Academy of the Sciences, 38(2), 7-10 (1993) That’s why wooden bats have always be… Why Wood Bats? As a result, fewer and fewer younger professional pitchers throw inside pitches than used to be the norm in years past. Because of shortages of quality wood, and the higher cost of good quality bats, most college teams completely switched over to aluminum bats during the 1980's. The point I want to make, however, is that Piazza's bat broke. Greenwald, "Batted Ball Speed as a Function of Swing Speed and Impact Location," presented at the 2001 Annual SGMA Baseball/Softball Industry Meeting, Chicago, IL (2001). A player can go through a wooden bat or more during a single game. The results of these two studies are in contrast to what players, coaches, and league officials all know - that metal bats do outperform wood bats. Thus, the bats used in this study are not representative of aluminum bats allowed for use at high school and college levels under current NCAA rules. Likewise hitters often find it to be considerably difficult to make the change from aluminum to wood, especially when dealing with inside pitches. Omaha puts up a lot of cash and all the teams are endorsed by metal bat makers. The aluminum baseball bat was introduced into college baseball in 1974 as an economical answer to rising costs of replacing the large number of wood bats that were being broken during a season. Balls were pitched towards an initially stationary bat and the rebound speed of the ball was measured, with the result that aluminum and wood bats performed the same. Greenwald, "Metal baseball bats can outperform wood bats with a similar `sweet spot'," Proceedings of the 24th Annual Meeting, American Society of Biomechanics. There are no studies showing increase in injury due to use of non-wood bats and the rules currently make it such that the ball rebounds about the same from a non-wood bat ( called BESR rating) as from wood. Well, It might seem kind of cool when you first think about it, but don’t we want our pros to really show some skills to muscle a home run? In fact, the increased demand for alloy bats and especially the aluminum baseball bat has a number of reasons behind it. One of the most obvious differences in college baseball is the use of metal bats, which was first permitted by the NCAA back in 1975. Just like I pointed out from my early years, metal bats have a way of making the ball fly. Stodden and J.R. Andrews, "Relationship between bat mass properties and bat velocity," Sports Eng., 5, 1-8 (2002) Yankees pitcher Roger Clemens delivered an inside pitch to Mets catcher Mike Piazza. Sports Exerc., 21, 199-205 (1989) Is one better than the other? A total of 19 players (nine minor-leaguers, six NCAA college, four high school) participated in the study, swinging two wood bat models, and 5 different metal bat models (6 bats of each model). Aluminum baseball bats first came onto the scene back in the early 1970s, and over the years have gradually phased out wooden bats in youth baseball mainly for economic reasons. Greenwald R.M., L.H. They learn while playing in highschool and college that inside pitches get hit for runs. [12] Julavrits, "Bat Rap," Sport, 90(6), 26 (June, 1999) The plot clearly shows that the higher performing bats have a lower hoop frequency, which indicates that the simple mass-spring model of the trampoline effect captures the essential physics. Professional leagues use wooden baseball bats, but at all levels of amateur play, including college play, players use metal bats. The apparent discrepency appears to be that "Despite the amount of controversy generated, there are presently no available data describing the performance of metal and wood bats in the field. The reason why high schools and colleges use aluminum bats over wood is … Marucci Cat8 -3 College Baseball Bat. Sci.
