Oregon Fall ID/PNW Fall ID: Pitcher Data Dive


Josh Schoenberg
Scouting and Operations Assistant

On September 23rd, PBR Oregon hosted its first showcase of the fall 2023 circuit: The Oregon Fall ID. On October 14th, the staff hosted its final event: The Pacific Northwest Fall ID  Perennially, showcases helps introduce our staff to new need-to-know players in the state that we’d not yet seen before, as well as provided us with updated looks at players who’ve earned our attention in the past.

Now, we will take a further in-depth look at the top pitchers with the help of our tech partnerships, broken down by the categories down below:

TRACKMAN

FASTBALL

VELOCITY (MAX)

Rank Name State School Class Pos Velocity (max)
1 Ian Kolmer OR Ida B Wells 2025 OF 83.0 mph
2 Jacob Chandler WA Union 2026 3B 82.4 mph
3 Jacob Griffith WA Skyview 2025 OF 81.3 mph
4 Harrison Buckingham OR South Salem 2027 RHP 80.3 mph
5 August Ware OR Glencoe 2026 LHP 79.5 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 Jacob Griffith WA Skyview 2025 OF 2299 rpm
2 Collin McGowan WA Battle Ground High School 2028 C 2229 rpm
3 Griffin O'Neil OR Tigard 2024 RHP 2225 rpm
4 Miles Ott OR Tigard 2025 RHP 2092 rpm
5 Cooper McGowan WA Battle Ground 2027 SS 2052 rpm
6 Ian Kolmer OR Ida B Wells 2025 OF 2035 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 James Pearson OR Valley Catholic 2024 RHP 21.0 in
2 Michael Neumayer OR Sherwood 2027 3B 18.6 in
3 Cooper McGowan WA Battle Ground 2027 SS 18.1 in
4 Ian Kolmer OR Ida B Wells 2025 OF 17.8 in
5 Ryan Gresham OR Sunset 2027 C 17.3 in
6 Harrison Buckingham OR South Salem 2027 RHP 16.9 in
7 Lucas Brazier WA White River 2026 SS 15.8 in
8 Collin McGowan WA Battle Ground High School 2028 C 15.1 in
9 Benito Rinaldi OR Lake Oswego 2025 2B 14.8 in
10 Jacob Griffith WA Skyview 2025 OF 14.0 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 August Ware OR Glencoe 2026 LHP -18.7
2 Jacob Chandler WA Union 2026 3B 15.7
3 Harrison Buckingham OR South Salem 2027 RHP 15.1
4 Ryan Gresham OR Sunset 2027 C 13.1
5 Cooper McGowan WA Battle Ground 2027 SS 11.8
6 Ian Kolmer OR Ida B Wells 2025 OF 10.5
7 Benito Rinaldi OR Lake Oswego 2025 2B 9.8

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 Jacob Chandler WA Union 2026 3B 66 %
2 August Ware OR Glencoe 2026 LHP 63 %

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