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.

Major League Baseball's I-Team
Major League Baseball’s I-Team The I-Team is composed of players whose names contain enough unique letters to spell the team(s) for which they played. To select the team, the all-time roster for each franchise was compared to both its current name as well as the one in use when each player was a member of the team. For example, a member of the Dodgers franchise would be compared to both that moniker (regardless of the years when they played) as well as alternate names, such as the Robins, Superbas, Bridegrooms, etc., if they played during seasons when those other identities were used. However, if a franchise relocated and changed its name, the rosters would only be compared to the team name used when each respective player was a member. Using another illustration, those who played for the Senators from 1901 to 1960 were not compared to the Twins name, and vice versa. Finally, the most common name for each player was used (as determined by baseball- reference.com’s database). For example, Whitey Ford was used, not Edward Ford.

Specifically, I look at both the influence ofhow various Latin American cultures teach the game in orderto better ensure success ofplayers at the MLB level versus how the game is taught in the United States and Japan. Inthis way I develop a feedback modelin whichthese game strategies perpetuate acycle ofenculturation that further reinforces cultural/ethnic identities. -
Brandon Belt
BRANDON BELT • Born April 20, 1988, in Nacogdoches, Texas, in a house his father built. • Parents are Darrell and Janice (pronounced Ja-neece). He has one younger brother, Cameron. Father is a geometry teacher at Brandon’s high school, Hudson High in Lufkin. His mother is a hairdresser. • As a senior at Hudson High, Belt earned district MVP, All-State and All-Amer- ica honors. Standout pitcher – thought he’d make the major leagues in that position. • Had a verbal agreement with Cubs coming out of high school to be drafted in high rounds and paid high-round money. But Cubs didn’t come through and Red Sox drafted him the 11th round. Disappointed, Belt went to college instead. “Everything I went through happened for a reason,’’ he says. “I’m so happy I went to college. I matured so much as a baseball player and as a person and I made so many friends.’’ • Played one year for San Jacinto College in Houston before transferring to University of Texas. (Same two colleges Roger Clemens attended.) Majored in education. Helped propel Texas to the College World Series in 2009, where the Longhorns lost in the Championship game to LSU. • Injuries as a junior at University of Texas forced him to give up pitching altogether. When his hitting dropped off – he was barely hitting .300 two thirds into his junior year – Brandon sank to the lowest point in his life. He had always wanted to be pro baseball player and now he was wondering if he would make it. Then his grandfather, James Peter- son, died. -

Thank you. v Suggesting Pitches in Major League Baseball by Javier Palomares, Jr., MSE The University of Texas at Austin, 2019 Supervisors: Constantine Caramanis and Alexandros Dimakis Pitchers in Major League Baseball need to keep batters from anticipating the next pitch. They do this by selecting a good pitch type and zone to throw. Pitchers often make this selection haphazardly. In this paper, we present a machine learn- ing model using the data from the PITCHf/x system installed in Major League stadiums to first predict good and bad pitches, and then to suggest the following pitch type to throw that will result in good outcomes. vi Table of Contents List of Figures 1 1 Selecting the Pitch to Throw 2 2 Relevant Work 3 2.1 Predicting whether the Next Pitch is a Fastball.................................... -
Deriving Spin Signatures and the Components of Movement from Trackman Data for Pitcher Evaluation 1 Introduction
Deriving Spin Signatures and the Components of Movement from Trackman Data for Pitcher Evaluation Glenn Healey Electrical Engineering and Computer Science University of California, Irvine, CA 92617 Email: [email protected] Research Paper for 2019 SABR Analytics Conference 1 Introduction The 3-D pitch trajectories and total spin measurements acquired by the Trackman radar enable the recovery of the spin axis for individual pitches. We leverage a computational process proposed by Alan Nathan [6] in combination with fine-grained weather data to compute this recovery for every MLB pitch over a full season. This analysis allows the creation of a new spin signature representation for characterizing and comparing pitchers. As shown in Figure 1, three forces act on a baseball traveling through the air with a velocity vector v. Gravity pulls the ball down, drag acts opposite the velocity direction, and the Magnus force causes the ball to change direction due to spin. Figure 1: Forces on a spinning baseball in flight The Magnus force depends on the spin vector ω and causes movement [5] [7] on a pitch. The spin vector ω has a magnitude defined by how fast the ball is spinning, e.g. 2400 1 revolutions per minute (rpm), and a direction defined by the spin axis and the right-hand rule as shown in Figure 2. A pitcher controls the spin axis with the orientation of his hand and fingers when he releases a pitch. The direction of ω can be represented by the unit vector ω = ω/|ω|. b Figure 2: Spin axis and spin vector direction The magnitude of the Magnus force [8] is given by 1 |F | = ρAC |v|2 (1) M 2 L where ρ is the air density, A is the ball cross-sectional area, and CL is the dimensionless lift coefficient. -

The Boston Red Sox Thursday, April 6, 2017 * The Boston Globe Chris Sale sparkles in Red Sox debut Nick Cafardo The love affair between Chris Sale and Red Sox fans started on Opening Day with a prolonged standing ovation as he was introduced. It continued as he walked to the bullpen Wednesday to do his warm-up prior to his first Sox start, as the fans cheered and were “out of their minds,” as Sale put it, to see him. It didn’t end there, either. As he walked off the mound after the top of the seventh inning, the cheers continued. And why not? Sale didn’t disappoint, striking out seven and leaving a scoreless game the Sox won when Sandy Leon hit a walkoff three-run homer in the 12th. Sale threw his first pitch at 97 miles per hour. Most of the rest were between 92 and 94. He had a fabulous slider and excellent changeup. There wasn’t much Sale couldn’t do in his first Red Sox outing. “I felt good,” he said. “I felt confident I could throw all of my pitches for strikes, whether I was ahead on the count or behind. The credit goes to Sandy. He called the pitches. I just threw them.” As for his state of mind, Sale said, “I get nervous before every game, but tonight was different because it was my first time pitching for the Red Sox. Running out of the first base dugout was awesome. It was special. I tried to go through my normal routine and do everything I normally do, but I also wanted to soak it all in. -
