Sabermetrics is the empirical analysis of baseball statistics to evaluate player performance and team strategy. It uses mathematical and statistical methods to gain insights into the game, moving beyond traditional metrics like batting average and earned run average. By focusing on advanced statistics, such as on-base percentage and wins above replacement, sabermetrics helps teams make informed decisions about player acquisitions, game tactics, and overall performance. This analytical approach has transformed how teams assess talent and strategize, leading to a more data-driven understanding of baseball.
