Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
