On June 7, the PBR Illinois staff kicked off our summer tour with the Underclass Open, held at Triton College in River Grove, Ill. Previously touted as the Underclass Trials, this event has been a staple on our summer calendar since 2014. It routinely provides us an opportunity to check see prospects prior to the summer circuit kicking off, and this year’s event featured players from the 2024-2026 grad classes.

Earlier this week we published Quick Hits highlighting the top prospects of the event by class. We also rolled out a Statistical Analysis, bringing you a quick statistical analysis of those that participated in the event. We then dove deep into the data, looking at the pitch metrics and batted ball numbers from this event inside our TrackMan Files piece.

Today, with the help of our Blast Motion sensors, we're analyzing the swing metrics measured on Saturday at this high-caliber showcase.

Hand Speed (Peak & Average)

Peak Hand Speed: The observed maximum speed as measured on the handle of the bat (measured six inches from the knob of the bat). Peak Hand Speed will occur prior to the moment of impact, very close to the commit time in the swing when the wrists unhinge.

Bat Speed (Average)

Bat Speed: The observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.

Rotational Acceleration (Peak & Average)

Body Rotation: A swing that has the appropriate relative contributions of body and bat rotations is an efficient and Powerful swing that maintains proper sequencing. An efficient baseball swing is one in which the body creates the initial movements, which is then transferred to the arms and out to the bat, thereby maximizing Bat Speed through this proximal-to-distal kinematic sequencing movement pattern.
