In recent years, advanced metrics have dominated the game of Major League Baseball. One such metric, the Pythagorean Win-Loss Formula, is commonly used by fans, reporters, analysts and teams alike to use a team’s runs scored and runs allowed to estimate their expected winning percentage. However, this method is not perfect, and shows notable room for improvement. One such area that could be improved is its ability to be affected drastically by a single blowout game, a game in which one team significantly outscores their opponent.<br/>We hypothesize that meaningless runs scored in blowouts are harming the predictive power of Pythagorean Win-Loss and similar win expectancy statistics such as the Linear Formula for Baseball and BaseRuns. We developed a win probability-based cutoff approach that tallied the score of each game once a certain win probability threshold was passed, effectively removing those meaningless runs from a team’s season-long runs scored and runs allowed totals. These truncated totals were then inserted into the Pythagorean Win-Loss and Linear Formulas and tested against the base models.<br/>The preliminary results show that, while certain runs are more meaningful than others depending on the situation in which they are scored, the base models more accurately predicted future record than our truncated versions. For now, there is not enough evidence to either confirm or reject our hypothesis. In this paper, we suggest several potential improvement strategies for the results.<br/>At the end, we address how these results speak to the importance of responsibility and restraint when using advanced statistics within reporting.
In 2021-2022, MLB underwent a labor stoppage due to a failure between the league and union to sign a new collective bargaining agreement (CBA) for the 2022 season until mid-March of 2022. This failure led to a contentious debate between owners and players over economic, competitive balance, and gameplay issues. To evaluate how MLB has reached this point in labor relations and make predictions for the future, it is first important to look at the history of sports and collective bargaining and, more specifically, this history in baseball. Next, one should evaluate the history of the antitrust exemption and its impact on labor relations in MLB. It is then important to analyze the main tenets of the 2022 CBA and their implications. Following this historical and current analysis, one can make hypotheses about where baseball labor relations and antitrust laws are heading and what will be key issues to look toward in the future.
