Box 190 Yachats, OR 97498, USA Received 21 July 2005; received in revised form 30 May 2006; accepted 5 June 2006 Abstract The right-hand rules show the direction of the spin-induced deflection of baseball pitches: thus, they explain the movement of the fastball, curveball, slider and screwball. The direction of deflection is described by a pair of right-hand rules commonly used in science and engineering. Our new model for the magnitude of the lateral spin-induced deflection of the ball considers the orientation of the axis of rotation of the ball relative to the direction in which the ball is moving. This paper also describes how models based on somatic metaphors might provide variability in a pitcher’s repertoire. ᭧ 2006 Elsevier Ltd. All rights reserved.

ABSTRACT ROLE OF MATERIAL & DESIGN ON PERFORMANCE OF BASEBALL BATS by Kim Benson-Worth Baseball bat safety has become an increasing area of interest with more than 19 million people in the United States alone participating in this sport. An increase in injuries resulting from bat injuries has brought the performance of the bats into question.

  • Baseball Social Distancing: • Practice – Coaches Are Responsible for Ensuring Social Distancing Is Maintained Between Players As Much As Possible
    Baseball Social distancing: • Practice – Coaches are responsible for ensuring social distancing is maintained between players as much as possible. This means additional spacing between players while playing chatting, changing drills so that players remain spaced out, and no congregating of players while waiting to bat. Workouts should be conducted in ‘pods’ of students, with the same 5-10 students always working out together. This ensures more limited exposure if someone develops an infection. • Dugouts – No dugouts should be used during practice. Players’ items should be lined up outside and against the fence at least six feet apart. Dugouts should be permitted only during games, and may be extended, by NFHS rule, down the foul lines outside the playing area to allow for social distancing. Additionally, bleachers can be placed directly behind the dugouts for additional seating for team personnel. Players should maintain social distancing unless they are actively participating in the game. • Field of Play – Only essential personnel are permitted on the field of play. These are defined as players, coaches, athletic trainers, and umpires. All others, i.e., ball/bat shaggers, managers, statisticians, pitch count designees, media photographers, etc. are considered non-essential personnel and are not to be in the dugout or extended dugout area. • Spectators – Schools must limit the use of bleachers for fans. Schools should encourage fans to bring their own chairs or stand. Fans should practice social distancing between different household units and accept personal responsibility for public health guidelines. • Media – All local social distancing and hygiene guidelines for spectators should be followed by media members planning to attend games.

  • An Experimental Investigation of the Effect of Use on the Performance of Composite Baseball Bats
    Proceedings of 7th ISEA CONFERENCE 2008 Biarritz, June 2-6, 2008 An Experimental Investigation of the Effect of Use on the Performance of Composite Baseball Bats James A. Sherwood 1 and Patrick J. Drane 2 (1) : One University Ave. Lowell, MA 01854 (2) : 1-978-934-2995 USA E-mail : [email protected] 1-978-934-3313 E-mail : [email protected] TOPICS: Composites, baseball, bats Abstract: The choice of materials used to make baseball bats has evolved over the years from traditional solid wood to aluminium and now to composites. To determine whether or not a bat’s design is in compliance with the batted-ball performance standard for a given league, a new bat is tested in a hitting machine where the bat is subjected to a limited number of hits. Considering the material behaviour that occurs within a composite material subjected to numerous impacts, the batted-ball performance of composite bats can theoretically improve with use as the polymer-matrix develops microcracks. These microcracks can soften the barrel of the bat which may allow the trampoline effect to increase. As the trampoline effect increases, there is potential for the batted-ball speed to increase. This paper will discuss the observed evolution of the performance for six currently popular composite baseball bats that were subjected to cycles of performance testing followed by repeated use in a controlled laboratory setting. None of the six composite baseball bats exhibited a significant change in performance. Some of the composite bats did exhibit poor durability. Key words: Composites, baseball, bats, performance, durability.
