Describing Baseball Pitch Movement with Right-Hand Rules
Computers in Biology and Medicine 37 (2007) 1001–1008 www.intl.elsevierhealth.com/journals/cobm Describing baseball pitch movement with right-hand rules A. Terry Bahilla,∗, David G. Baldwinb aSystems and Industrial Engineering, University of Arizona, Tucson, AZ 85721-0020, USA bP.O. 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. -
