Baseball Pitch Count Software
PITCH COUNT RULES. Number of pitches allocated for 3 rd grade – 6 th gradeRegular Season. 60 or greater pitches per day/72 hours rest.
40-59 pitches/40 hours rest. 21-39 pitches/24 hrs rest.
0-20 pitches/No rest requiredPlayoffs/Tournament. 60 pitches/40 hrs rest.
40 pitches/24hrs rest. Daily (calendar day) and Weekly (Sunday through Saturday) Pitch Limits per Age. If a player pitches more than 35 pitches in a day, he will not be allowed to play catcher for the remainder of that calendar day.
If a player pitches between 20 and 35 pitches and then subsequently plays catcher in the same game, the player must observe 40 hours of rest before pitching again. Additionally, if a player plays catcher 4 innings in one game (one pitch in one inning constitutes a full inning for catching purposes), the player cannot pitch the same calendar day. If a pitcher reaches the daily pitch limit above for his/her league age while facing a batter, the pitcher may continue to pitch until that batter reaches base or is put out. All pitches (including those pitched to finish the last batter) count against the weekly pitch count. If a pitcher reaches the weekly pitch limit imposed in Rule 2 above for his/her league age while facing a batter, the pitcher may continue to pitch until that batter reaches base or is put out. The Game Commissioner will track each pitcher’s number of pitches as well as the time the pitcher completes his final pitch and physically leaves the mound in the official scorebook.
The coach is responsible for knowing when a pitcher must be removed. The Game Commissioner should inform the umpire and coaches when a pitcher has delivered the maximum limit for pitches (game, daily, weekly) and that the pitcher should be removed.
Failure by the Game Commissioner to notify the umpire and coaches does not relieve the coach’s responsibility to remove the pitcher when that pitcher is no longer eligible. Should a pitcher exceed the required daily or weekly pitch count limit the head coach and team may be penalized.
These penalties may include but are not limited to letter of reprimand, suspension, or game forfeiture. Offending Coaches may appeal each penalty before the overall baseball commissioner for final determination.
This page mainly contains links to articles on the PITCHf/x system for tracking pitched baseballs. In the near future, additional links will be added on the HITf/x and FIELDf/x systems for tracking batted balls and people on the field.A superb article written by analyst Mike Fast ( ) for The Hardball Times Annual 2010. This is a great place to start learning about what this new technology is all about and what it is good for. Mike is one of the premier PITCHf/x analyzers.
A pioneering article by Peter Jensen published in the June 30, 2009 issue of The Hardball Times. Peter is the first person to recognize the value of HITf/x data for establishing 'outcome-independent' hitting metrics.This is an article I wrote in October 2012 in which I discuss the concept of pitch movement, including how it is defined and how it is calculated using the PITCHf/x tracking system. I indicate why that technique does not exactly conform to the definition and further indicate how to correct it so that it does. I give some examples of how the improved technique can affect baseball analysis. A template in the form of an Excel spreadsheet is to do the actual calculations.This is a link to an article by Matthew Mata that appeared June 29, 2013 in FanGraphs. The article describes a procedure to determine the mean distance from home plate of a pitcher's release point by minimizing the area subtended by the distribution of transverse coordinates of the pitches as a function of home plate distance. As a added bonus, another outcome of the analysis is the pitcher's arm slot.
The article describes some interesting mathematical and statistical techniques; nevertheless, the writing is very clear and the article should be accessible to many readers, even those without a mathematical background., a panel discussion of the latest developments in Sportsvision's PITCHf/x, HITf/x and FIELDf/x, and TrackMan's radar technology used to measure ball flight, presented at SABR40 in Atlanta, August 7, 2010. The panel members were Rand Pendleton (Sportvision), Rob Ristagno (TrackMan), Dave Allen (Fangraphs and Baseball Analysts), Josh Kalk (Tampa Bay Rays), and myself. The zip file contains the talks that were presented by each of us.and, articles thatwere published in. The first article is a brief introduction to the FIELDf/x system and is co-written by Greg Rybarczyk, inventor of the, and Kate McSurley of Sportvision.
FIELDf/x is an enhancement to the pitch-tracking PITCHf/x system and uses multiple cameras to track everything on the playing field: the fielders, the umpires, the base runners, and the batted ball. The second article about True Defensive Range is written by Greg. It is the finest piece of publicly available analysis using FIELDf/x data that I have seen and is a must read for anyone interested in advanced fielding metrics. Thanks to Greg and to Dave Studeman, manager of The Hardball Times, for allowing me to post the articles here. Greg talked about this work at the annual in 2010 and 2011., an article by ( ) appearing February 4, 2012 in The Hardball Times. In the article, Dan announces his new player cards, a collaborative effort with THT writers ( ) and ( ). The pitch classifications are done by hand, a remarkable effort, and are almost surely the best available.
The plots available for each pitcher are both informative and beautifully put together. This is great stuff by some of the best PITCHf/x analysts still unhired by MLB teams.As of February 1, 2012, Mike Fast is no longer a free-lance analyst, having taken a position in the Baseball Operations department of the Houston Astros. Best wishes to Mike for success in his new position.Here are links to some of the articles he has written., The Hardball Times, June 17, 2010 (PITCHf/x pitfalls)., Baseball Prospectus, February 16, 2011., Baseball Prospectus, June 1, 2011., Baseball Prospectus, March 2, 2011., Baseball Prospectus, November 16, 2011., Baseball Prospectus, November 22, 2011: This is the company responsible for the pitch-tracking technology, including the software used to reconstruct the trajectory in real time and render it for the broadcasters. They are also the people who created the virtual yellow first-down marker used in television broadcasts of football games.

If you know how to use SQL, this is far and away the easiest way to obtain the data. If you don't, then check the next link., an excellent primer by Colin Wyers on SQL. This is how I learned whatever little I know about the subject.is the patent application of Marv White and Alina Alt. This document discusses the various techniques that can be used to determine the trajectory in field coordinates (x,y,z) from the camera pixel information., a document written by Rand Pendleton of Sportvision giving the mathematical details that are used to convert pixel information into a constant-acceleration trajectory. The general technique outlined here can easily be extended to include arbitrary numbers of cameras or to utilize different physical models for the trajectory.: How to use the PITCHf/x data to get improved values for the break of the pitch due to the spin of the ball.
