These are important because they show you how often (on average) a player walks and strikes out. Unlike batting average, K% and BB% are given in a direct percentage format, so there’s no need to translate it. The application of these stats is pretty straightforward; a player with a high BB% and low K% would typically have a good batting eye, and a player with opposite-type numbers would typically have a poor batting eye.
While hitting for a high batting average does not exclude hitting for power, the most successful batters with the highest averages are very good at situational hitting. This means that they can identify gaps in defensive coverage or anticipate pitches better, giving them more of an advantage at the plate. A typical player with a high batting average is patient at the plate and can hit the ball effectively to both sides of the field.
