Sabermetrics: the Past, the Present, and the Future
Sabermetrics: The Past, the Present, and the Future Jim Albert February 12, 2010 Abstract This article provides an overview of sabermetrics, the science of learn- ing about baseball through objective evidence. Statistics and baseball have always had a strong kinship, as many famous players are known by their famous statistical accomplishments such as Joe Dimaggio’s 56-game hitting streak and Ted Williams’ .406 batting average in the 1941 baseball season. We give an overview of how one measures performance in batting, pitching, and fielding. In baseball, the traditional measures are batting av- erage, slugging percentage, and on-base percentage, but modern measures such as OPS (on-base percentage plus slugging percentage) are better in predicting the number of runs a team will score in a game. Pitching is a harder aspect of performance to measure, since traditional measures such as winning percentage and earned run average are confounded by the abilities of the pitcher teammates. Modern measures of pitching such as DIPS (defense independent pitching statistics) are helpful in isolating the contributions of a pitcher that do not involve his teammates. It is also challenging to measure the quality of a player’s fielding ability, since the standard measure of fielding, the fielding percentage, is not helpful in understanding the range of a player in moving towards a batted ball. New measures of fielding have been developed that are useful in measuring a player’s fielding range. Major League Baseball is measuring the game in new ways, and sabermetrics is using this new data to find better mea- sures of player performance. -

THE SWEET SPOT of a BAT OR RACQUET Rod Cross Physics Department, University of Sydney, Sydney, NSW 2006 Australia the Sweet Spot
THE SWEET SPOT OF A BAT OR RACQUET Rod Cross Physics Department, University of Sydney, Sydney, NSW 2006 Australia The sweet spot of a bat or racquet is sometimes identified as a vibration node, sometimes as the centre of percussion (COP) and sometimes as the impad point where the ball rebounds with maximum speed. The batter or player is more likely to identify the sweet spot as the impact point that results in minimum shock and vibration, and therefore as the point that feels best. Theoretical and experimental results described in this paper indicate that the sweet spot is a narrow zone, located between the fundamental vibration node and the COP, where the energy transferred to the handle is minimised. KEY WORDS: sweet spot, bat, racquet, centre of percussion, vibration node INTRODUCTION: The sweet spot of a baseball bat or a tennis racquet is rewgnised by most players as the point that feels best when the ball is struck. The player feels almost no shock or vibration for an impact at the sweet spot. Conversely, the impact can be moderately painful for an impact well removed from the sweet spot. Various studies (eg Brody, 1986) have indicated that the sweet spot might coincide with the fundamental vibration node of the bat or racquet, or it might coincide with the centre of percussion (COP). Many authors assume that the sweet spot also coincides with the point at which the ball rebounds with the maximum possible speed. The latter assumption is clearly incorrect. If a tennis ball is incident on a stationary racquet, it bounces best near the throat of the racquet and worst near the tip. -
The Physics of Baseball Bats
Get In The Swing of Physics The Physics of Baseball Bats David Kagan Department of Physics California State University, Chico [email protected] Physics and Baseball Web Site: phys.csuchico.edu/baseball The Physics of Baseball Bats Sorry, but I was watching the MLB playoffs and….… The Physics of Baseball Bats Conservation of Momentum The Physics of Baseball Bats Conservation of Momentum The Physics of Baseball Bats To understand the images produced by the camera we need to investigate two key ideas: • Center of Percussion (CP) • Vibrational Nodes (VN) The Physics of Baseball Bats Center of Percussion (CP) We locate the CP by finding where we can hit the stick so that there is no jerk at the top. In other words, the bat goes into pure rotation. For the simple stick the CP is 2/3 of the way down the bat. This is where you want to hit the ball so you don’t get thrown around by the motion of the bat handle. The Physics of Baseball Bats Vibrational Nodes (VN) You can demonstrate vibrational nodes with a flexible stick. The Physics of Baseball Bats If you wrap a paper megaphone around the top of the stick you can hear the vibrations. The place where the sound is minimum is the VN. For the simple stick, the node is ¾ of the way down the bat. At the node, little energy will go into bat vibrations, leaving more energy in the ball. The Physics of Baseball Bats The CP and the VN are in different spots for a simple stick. -
Basics of the Two Man Umpiring System
NHBUA Field Mechanics 1 TWO MAN MECHANICS Conventions used to designate players or locations UIC = Plate Umpire BU = Base Umpire F# = Number designating a fielder position (F1 = Pitcher) #B = base (1B = first base) HP = home plate Pos A/B/C = Position A/B/C R# = Runner and base B = batter BR = batter-runner IF = Infield OF = Outfield AB = At Bat Definitions The Box • An imaginary area in the IF that is a 45 foot square with one corner at HP and the opposite corner at the mound. Working lane • The area on the IF grass running parallel with the baselines between first and second and second and third in which the BU moves while the defensive is playing a batted ball. Sweet spot • The area behind the mound that allows for excellent angles on all plays made at the bases. Secondary sweet spots are designated on each side of the mound. A Play • The course of action in which the defense attempts to put out a runner. Two things are required; the ball and a runner. The “V” • The area on the field between F7 and F9 in which the BU has catch/no catch responsibility. This area is specified on Page 5. Rotation • A specific change in position made by each umpire in response to the ball put in play. Pressure • This term derives from the movement of F3 or F4 while making a play on a batted ball which forces the BU to clear the area around POS A so as not to impede play. Time Play • The situation in which the possibility exists that a run may cross the plate close to or at the same time the third out of an inning is made on the bases. -
Wagner Claims Two of Northeast Conference's Four Major Baseball
Northeast Conference 200 Cottontail Lane • Vantage Court North • Somerset, NJ 08873 (732) 469-0440 • Fax (732) 469-0744 • www.northeastconference.org For Immediate Release May 20, 2009 Contact: Ralph Ventre (ext. 7) Wagner Claims Two of Northeast Conference’s Four Major Baseball Awards Mount St. Mary’s Shane Eyler Named Akadema NEC Player of the Year of Year Wagner’s Matt Watson Awarded Akadema NEC Pitcher of the Year honors Fairleigh Dickinson’s Matt Holsman Garnered Akadema NEC Rookie of the Year Status Wagner’s Joe Litterio Tabbed Akadema NEC Coach of the Year Somerset, NJ -- Wagner added to what has been a landmark baseball season on Staten Island Wednesday night. Fresh off their first-ever Northeast Conference regular season crown, the Seahawks saw two of their own receive major honors when the NEC hosted its annual postseason awards banquet. Wagner junior right-hander Matt Watson (Howell, NJ/Howell), the league leader in earned-run average, claimed the Akadema NEC Pitcher of the Year honor and the veteran skipper Joe Litterio walked away with Akadema NEC Coach of the Year accolades. Mount St. Mary’s sophomore outfielder Shane Eyler (Taneytown, MD/Francis Scott Key) was a near-unanimous selection for the Akadema NEC Player of the Year award, the first time since 2005 a non-senior has held the honor. Fairleigh Dickinson freshman second baseman Matt Holsman (Coral Springs, FL/Stoneman Douglas) captured Akadema Rookie of the Year honors to give FDU its first major NEC postseason honor since the start of the decade. Sacred Heart, the runner-up to Wagner in the NEC standings, placed the highest number of representatives on the All-Northeast Conference Teams, which the league also unveiled on the eve of the 2009 NEC Baseball Championship presented by Akadema. -
The Physics of Baseball
Washington University in St. Louis Baseball Lab Introductory Physics Lab Fall 2015 The Physics of Baseball Pre-Lab: America’s National Pastime A Bit of History Filled with men, myths, and legends, the history of baseball is much too long to be described in any Bit of History. If you’re interested in A Lot of History, check out the excellent documentary titled Baseball – A Film by Ken Burns. But be warned: it is 18.5 hours long. For our purposes, it is sufficient to know that sometime in the late 1860s, the first professional baseball teams formed in the U.S. (our very own St. Louis Cardinals made their debut in 1882) and since that time the sport has become intertwined with American culture. No place is this truer than here in America’s greatest baseball town! What Is This Lab About? By the end of this lab you should see the tremendous number of physics topics that show up in the game of baseball. You’ll get to revisit topics such as momentum, impulse, projectile motion, the drag force, moment of inertia, cross-products, constant acceleration equations, energy, center of mass, and spherical cows. You will also be introduced to the Magnus force, waves, and the center of percussion. Whew! If you are already familiar with baseball, you can skip to the section titled “The Pitcher” at the top of page 3. The next couple sections attempt to explain some of the game to newcomers. The Game A game of baseball is played between two teams, each using nine players. -
Spartan Pitching Handbook (Compiled and Written by Greg Mueller, Revised December, 2009)
Spartan Pitching Handbook (Compiled and written by Greg Mueller, revised December, 2009) General Pitching Philosophy – “Believe in the Power of One” These are some, but not all, of the ideas you will need to become an excellent Spartan pitcher. During the course of the season, the coaches will give you other information to develop your pitching skills and understanding – listen carefully and work hard – in order to advance as an individual player and contribute to the team’s success. “Pitching is what the game is all about. Pitching IS the game.” (Bob Welch, 1990 Cy Young winner) The pitcher is “the only offensive player on the defensive field. Action begins when the pitcher delivers the ball. He is pro-active; the hitter is reactive….All too often, however, the pitcher forfeits that edge.” (H.A. Dorfman, pitching instructor/counselor for Oakland A’s, Florida Marlins, Tampa Bay Devil Rays) Pitching is 90 – 95 percent of the game, therefore, you need to be LEADERS of the team in practice as well as in games – set the tone with a confident attitude and exemplary work ethic. You need to give 100% on all drills, duties and routines. Live by these principles, “practice centers around getting better every day”, “perfect practice makes perfect” and “practice hard or go home”. SUCCESS in pitching requires 1. Excellent physical conditioning / strength – you will need to run more than position players to get your legs in shape because when the legs get tired your mechanics breakdown; you will need to do med ball wall and throwing exercises to strengthen your core muscles to promote better hip rotation which will increase your velocity; and, you will need to do arm circles. -

MEDIA CLIPS – Dec. 22, 2018 Rockies, Daniel Murphy agree to 2-year deal By Thomas Harding MLB.com @harding_at_mlb Dec. 21st, 2018 DENVER -- Seeking a big-game-tested hitter, the Rockies reached agreement on a two-year, $24 million contract with lefty-swinging veteran Daniel Murphy on Thursday, the club confirmed on Friday. Murphy, who will be 34 on April 1, has spent the majority of his career at second base, but the Rockies are planning to play him at first base. It means Ian Desmond, who has played primarily at first in the first two seasons of his five-year, $70 million contract, will move to the outfield -- most likely center, with Charlie Blackmon moving to left and David Dahl playing right. Left-handed-hitting Ryan McMahon, who played primarily first base in his rookie season, is expected to move to second, where the Rockies also have Garrett Hampson. While the plan is to play Murphy at first and allow the younger players to handle second, there could be some occasional games at second for Murphy, with Desmond moving back to first. The Rockies have made the postseason for two straight seasons (for the first time in their 26-season history) but offensive struggles led them to seek help at first base. The Rockies considered trading with the Blue Jays for first baseman Justin Smoak, but decided to go with Murphy -- a three-time All-Star (2014, '16 and '17) and the 2015 National League Championship Series MVP Award winner while with the Mets. Murphy emerged as a Rockies candidate during last week's Winter Meetings after attempts to obtain Carlos Santana and Edwin Encarnacion never came to fruition.
