Abstract
This document presents a quantitative study on the most effective types of pitches against Ronald Acuña Jr., a prominent baseball player, during the year 2020. Through an exhaustive methodology that includes data collection and analysis on pitch types, game conditions, and location, the project seeks to offer pitchers an analytical tool to improve their in-game decisions. Using the open-source platform Silver Decisions, a decision tree analysis allows the study identify patterns and trends in Acuña's at-bat behavior, offering specific strategies to deal with him in the most effective manner.
