Implicitly Defined Baseball Statistics
Implicitly Defined Baseball Statistics December 9, 2012 Joe Scott 1 Introduction Major League Baseball uses statistics to determine awards every season. The batting champion is given to the player with the highest batting average. The Cy Young Award is given to the top pitcher which is determined by many different statistics including earned run average (ERA). Batting average and ERA have been used for many years and are major statistics in baseball. Neither batting average or ERA consider the skill of the opposing pitcher or batter. Thus, every pitcher and batter is considered to have the same skill level. We develop an implicitly definded statistic that determines the skill or value of a player. The value of a batter and the value of a pitcher is based on the skill of the oppposing pitcher and batter respectively. We use linear algebra to find eigenvector solutions to the eigenvalue problem, Aλ = λx, which generates each player's statistical value. 2 Idea Consider a baseball league in which there are Nb players who bat, represented by bi for 1 ≤ i ≤ Nb. We represent the number of pitchers in the league as pj, 1 ≤ j ≤ Np where Np is the number of pitchers. Nb is defined as the number players who record an at bat during a specific season and Np is the number of players who record a pitching appearance during a season. The total number of players in the league, Ntp, is represented by the inequality Ntb ≤ Nb + Np. This inequality considers players who both hit and pitch. Since in the National League pitchers hit as well as pitch we need to add the pitchers to the total number of batters and in interleague play (which is when American League teams face National League teams in the regular season) American League pitchers bat when the National League team is home. -

The Stolen Base Is an Integral Part of the Game of Baseball
THE STOLEN BASE by Lindsay S. Parr A thesis submitted to the Faculty and the Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Master of Science (Applied Mathematics and Statistics). Golden, Colorado Date Signed: Lindsay S. Parr Signed: Dr. William C. Navidi Thesis Advisor Golden, Colorado Date Signed: Dr. Willy A. Hereman Professor and Head Department of Applied Mathematics and Statistics ii ABSTRACT The stolen base is an integral part of the game of baseball. As it is frequent that a player is in a situation where he could attempt to steal a base, it is important to determine when he should try to steal in order to obtain more wins per season for his team. I used a sample of games during the 2012 and 2013 Major League Baseball seasons to see how often players stole in given scenarios based on number of outs, pickoff attempts, runs until the end of the inning, left or right-handed batter/pitcher, run differential, and inning. New stolen base strategies were created using the percentage of opportunities attempted and the percentage of successful attempts for each scenario in the sample, a formula introduced by Bill James for batter/pitcher match-up, and run expectancy. After writing a program in R to simulate baseball games with the ability to change the stolen base strategy, I compared new strategies to the current strategy used to see if they would increase each Major League Baseball team’s average number of wins per season. I found that when using a strategy where a team steals 80% of the time it increases its run expectancy and 20% of the time that it does not, the average number of wins per season increases for a vast majority of teams over using the current strategy. -
