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
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

LHP/OF Johnny O’Brien (Fremd, 2026) emerged as a high-follow, two-way freshman with upside to all parts of his game. The 6-foot, 165-pound, left/left prospect, who also plays quarterback on tis a fluid, easy mover with long, loose-levers and polish on the mound. O’Brien has an easy, fluid delivery, threw a high-volume of strikes and ran his fastball into the low-80s with -14.1 inches of horizontal movement. He separated himself with his secondary offerings, showing a well above-average curveball that has a chance to be a plus offering down the road. He landed the high-spinning (2422 average rpm) 67-68 curveball for strikes throughout with the ability to manipulate it and create more sweep for back-foot action to a right-handed hitter. His 72-74 mph changeup is also an above-average offering for his age and gives him a starter profile moving forward. On top of that, he impressed just as much as a position player, running a 7.38 60 while showing off all kinds of fluidity and rhythm in the left-handed batters box to pair with quality actions in the outfield and a strong arm (T83 mph). O’Brien is a name to know in the Illinois’ 2026 class.
