Formula Explanation:
The formula for calculating BB/9 is: (Walks / Innings Pitched) * 9. This formula essentially measures the average number of walks a pitcher allows per nine innings.
Detailed Explanation:
BB/9 is a measure of the average number of walks a pitcher allows per nine innings, calculated as (Walks / Innings Pitched) * 9. This means that BB/9 rewards pitchers for allowing fewer walks.
Importance:
BB/9 is an important statistic in baseball as it is a key component of many other statistics and is a primary measure of a pitcher's control. A low BB/9 means a pitcher is allowing fewer walks, which gives their team a better chance to win.

If a pitcher allows 2 walks in 6 innings pitched, their BB/9 would be calculated as follows: (2 (walks) / 6 (innings pitched)) * 9.
