On Friday, February 13th, the Prep Baseball Ontario staff hosted it's first Preaseason Invite of the 2026 season with the annual Mississauga Preseason Invite, hosted at the Athlete's Turf, home of the Ontario Blue Jays, in Mississauga, Ontario.

This event featured roughly 80 prospects in the 2026 - 2029 classes and it was a strong group to open up three straight sold-out events in Ontario that will feature some of the top players in their respective classes as players are competing for roster spots on Canada/Ontario's National Team's at events such as the Future Games, Senior Future Games, West Coast Games, New York State Games, NorthEast Senior Games and the Best of the West.

All players ran through a full workout that included batting practice and bullpens captured on our TrackMan, swings captured by Blast motion, 30-yard with splits captured by VALD Performance and positional metrics. Over the next several days we'll be highlighting top performers from the event within our post-event analysis. Stay locked into our social media channels over the next several days as we continue to push out video, leaderboards and more.

Earlier this week, we broke down the top measurable data performers from the event with our Statistical Analysis article. 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:

FASTBALL

MAX VELOCITY (MPH)

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

SPIN RATE (AVG)

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.)

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.)

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.”
