Preseason All-State: Blast Motion Board
March 25, 2021
On March 20, the PBR Illinois team hosted its annual Preseason All-State showcase, bringing together a collection of the state’s best juniors in one place, Bo Jackson’s Elite Sports Dome in Lockport, Ill.
We began our post-event breakdown on Monday, detailing the prospects who exited the event with their prospect arrows pointed way up inside of this Quick Hits post. We highlighted the showcase’s biggest takeaways, focusing on the high-follow uncommitted juniors in the class, accompanied by written analysis and video. On Tuesday, with the help of our TrackMan unit on-site, we published TrackMan Files, and we published the traditional stat leaderboards on Wednesday, with added analysis on more of the event's top performers.
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.
