SoCal Uncommitted Games: Pitcher Data Dive
October 16, 2025
On Sunday, October 12th, the Prep Baseball California team hosted the SoCal Uncommitted Games at Cypress College in Cypress, Cal. This was an open event for high school classes (2026-2027), and gave our staff an ample look at the area's top prospects.
Over 40 players made their way to Cypress College and participated in a pro-style workout, gathering unrivaled access to data through our state-of-the-art tech partners, as well as in-depth scouting analysis from our Prep Baseball California staff.
Today, we will be looking at the top measurable data performers from the event, found below.

SPIN RATE (AVG.)
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |

2 | Eric Tani | CA | Harvard-Westlake | 2027 | SS | 2220 rpm |

Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.
INDUCED VERTICAL BREAK (AVG.)
Rank | Name | State | School | Class | Pos | IVB (avg) |
1 | Eric Tani | CA | Harvard-Westlake | 2027 | SS | 18.1 in |
2 | Jonas Jusay Jr | CA | Vista Murrieta | 2026 | LHP | 17.9 in |
3 | Grant Thomas | CA | Rancho Cucamonga High | 2027 | 1B | 17.0 in |
4 | Kane Clark | CA | Servite High School | 2027 | OF | 16.4 in |
5 | Zander Friedman | CA | de Toledo | 2027 | RHP | 16.1 in |
Induced Vertical Break: Used in short form as "IVB," this metric is most important on fastballs for creating rise and on curveballs for creating depth – it can also have some use when measuring sliders and cutters as well. Sliders tend to be closer to zero inches while cutters are generally between 5 and 15 inches. Usually fastballs and curveballs with large IVB have higher spin efficiencies as well. Sliders generally have very little (closer to zero) IVB and very low spin efficiencies. You could also categorize IVB into spin rate as this is part of the “useful movement” you’re looking for. IVB is also a huge part of vertical approach angle.
HORIZONTAL MOVEMENT (AVG.)
Rank | Name | State | School | Class | Pos | HM (avg) |
1 | Elsa Becher | CA | Helix | 2027 | 2B | 16.6 |
2 | Griffin Tagliaferri | CA | St. John Bosco High School | 2027 | LHP | -15.4 |
3 | Isaac Lulich | CA | Mira Costa High | 2027 | OF | -14.3 |
4 | Grant Thomas | CA | Rancho Cucamonga High | 2027 | 1B | 12.6 |
5 | Jonas Jusay Jr | CA | Vista Murrieta | 2026 | LHP | -12.5 |
Horizontal Break: Outlined on TrackMan’s own website: “... horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.”
STRIKE ZONE RATE%
Rank | Name | State | School | Class | Pos | Zone % |
1 | Grant Thomas | CA | Rancho Cucamonga High | 2027 | 1B | 52 % |

Average MLB pitchers throw 62% strikes, and better pitchers throw strikes 65% of the time, or roughly 2:1 strikes to balls.
