PBR Introduces Rise Score

RISE QUANTIFIED

Until now, the word 'rise' has been used to describe a fastball that vertically breaks up with velocity through the strike zone. You may say fastballs with extreme rise have a high elite backspin. 

Rising fastballs visually carry through the strike zone generating higher fly ball percentages when thrown up in the strike zone. A higher rise score has the potential to generate more whiffs, especially when paired with complimentary fastball movement characteristics that create a movement gap between the fastball and breaking ball. PBR’s goal was to be able to objectively quantify fastballs with rise characteristics across levels. 

What is a Rise? 

Rise is defined as a fastball that rises vertically with velocity through the strike zone. 

Rise Score

Using advanced pitch data metrics, PBR’s analytics department has developed a rise score to easily compare fastballs across multiple levels. 

Rise+ Stats

The Rise+ stat takes and normalizes our Rise score across an entire level. Rise+ is calculated by dividing a Pitcher’s rise by the mean rise of the level of play and multiplying by 100. In other words, the mean Hop is set to 100 and 1 unit above or below that is equal to being 1% above or below that mean for the level of play.

SUMMARY

We now have a simple way to objectively compare fastballs with rise characteristics between levels and over time with the Rise+ stat. The effectiveness of a fastball is very dependent on outside factors including location and pitch repertoire. In general, fastballs with higher Rise+ are more difficult to hit.
