Lower Mainland Fall ID: Pitching Data Dive
October 14, 2024
On Friday, October 11th, the Prep Baseball British Columbia staff hosted it's first of two Fall ID's with the Lower Mainland Fall ID at Whalley Stadium in Surrey, British Columbia. This event featured roughly 22 prospects from the Lower Mainland in the 2025 - 2028 classes and allowed our staff an opportunity to get an in-depth look at the players, as well as collect updated metrics via our tech partner TrackMan. Fall ID's allow players one final chance to update their metrics and profile before the winter season.
Earlier this week we began our post-event coverage within our Statistical Analysis article. Today we'll take a deeper dive into all of the data we collected from the event within this article as we provide leaderboards on each metric collected on TrackMan during bullpens at the event.

FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Linden Happell | BC | Maple Ridge | 2025 | RHP | 86.3 mph |
2 | Henry Pednaud | BC | Chatelech Secondary Sechelt | 2027 | RHP | 83.6 mph |
3 | Brydon White | BC | Lord Tweedsmuir | 2027 | C | 82.7 mph |
4 | Nathaniel Miranda | BC | White Rock Christian Academy | 2026 | 3B | 81.7 mph |
5 | Liam Smith | BC | not listed | 2025 | 1B | 80.4 mph |
6 | Ethan Gray | BC | Lord Tweedsmuir | 2028 | RHP | 79.3 mph |
7 | Isaac Rusch | BC | St. George’s | 2026 | RHP | 79.2 mph |
8 | Dominik Lakusta | BC | Johnston Heights Secondary School | 2026 | LHP | 78.5 mph |
Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.
SPIN RATE (AVG)
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Linden Happell | BC | Maple Ridge | 2025 | RHP | 2464 rpm |
2 | Henry Pednaud | BC | Chatelech Secondary Sechelt | 2027 | RHP | 2172 rpm |
3 | Jonathan Slogocki | BC | Holy Cross Regional | 2027 | RHP | 2090 rpm |
4 | Jonah Murray | BC | Yale Secondary | 2028 | 3B | 2040 rpm |
5 | Andrew Suttie | BC | GW Graham Secondary School | 2026 | LHP | 1995 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 | Jonathan Slogocki | BC | Holy Cross Regional | 2027 | RHP | 22.1 in |
2 | Andrew Suttie | BC | GW Graham Secondary School | 2026 | LHP | 22.0 in |
3 | Dominik Lakusta | BC | Johnston Heights Secondary School | 2026 | LHP | 20.6 in |
4 | Jonah Murray | BC | Yale Secondary | 2028 | 3B | 20.4 in |
5 | Matthew Crock | BC | Windsor Secondary | 2028 | LHP | 19.2 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 efficiency. 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 the vertical approach angle.
HORIZONTAL MOVEMENT (AVG.)
Rank | Name | State | School | Class | Pos | HM (avg) |
1 | Liam Smith | BC | not listed | 2025 | 1B | -14.6 |
2 | Linden Happell | BC | Maple Ridge | 2025 | RHP | 14.2 |
3 | Jonah Murray | BC | Yale Secondary | 2028 | 3B | 12.4 |
4 | Ethan Gray | BC | Lord Tweedsmuir | 2028 | RHP | 12.1 |
5 | Dominik Lakusta | BC | Johnston Heights Secondary School | 2026 | LHP | -11.6 |
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.”
