## What is FPS BF?

FPS BF stands for Fields Per Second-Ball Four. It is a statistic that measures the number of pitches a pitcher throws in an inning in comparison to the number of balls and strikes they give up. The statistic is calculated by taking the number of pitches an inning and dividing it by the number of balls and strikes given up. The higher the statistic, the more effective the pitcher is at getting batters out.

## How is FPS BF Useful?

FPS BF is a useful metric for evaluating the performance of relief pitchers. It measures the number of pitches an inning in comparison to the number of balls and strikes given up, which is a useful metric for measuring the effectiveness of a pitcher. It can also be used to evaluate the performance of starting pitchers, as it can provide a good indication of their ability to keep batters off balance and get them out.

Furthermore, FPS BF is a good way to compare the performance of different pitchers. If two pitchers have similar numbers of balls and strikes given up, but one pitcher is throwing more pitches per inning, then that pitcher is likely to be more successful. This can help coaches and scouts to identify which pitchers are the most effective in a given situation.

## What is a Good FPS BF?

A good FPS BF is one that is higher than the league average. Generally, a pitcher with an FPS BF of 1.0 or higher is considered to be an effective pitcher. This means that the pitcher is able to get batters out without giving up too many balls or strikes. Additionally, pitchers with an FPS BF of 1.5 or higher are considered to be elite, as they are able to get batters out with a higher frequency.

## Conclusion

FPS BF is a useful metric for evaluating the performance of a pitcher. It measures the number of pitches an inning in comparison to the number of balls and strikes given up, which can provide an indication of the effectiveness of a pitcher. Furthermore, it can be used to compare the performance of different pitchers. Generally, a pitcher with an FPS BF of 1.0 or higher is considered to be an effective pitcher, while pitchers with an FPS BF of 1.5 or higher are considered to be elite.
