Rapsodo - One of the most important tools we use here at Gradum, for 2 reasons:
It’s extremely important for our hitters to receive feedback on the progress they are making in real time
This keeps us (as instructors) accountable! Improvement is witnessed first hand, the data does not lie
This report give us a ton of data, but a few of the most important metrics we look at are exit velocity, spin direction, spin RPMs, and launch angle.
Exit velocity - The velocity at which the ball leaves the bat. The higher the exit velocity, the harder the ball is hit
Spin direction - This tells us HOW the ball is spinning when it leaves the bat. “00” on the clock is perfect backspin, and “06” on the clock is perfect topspin. We want to gear our swing to consistently spin the ball at 00!
Spin RPMs - This tells us HOW MUCH the ball is spinning when it leaves the bat. A “barreled baseball” will spin anywhere from 900-1600 RPMs, which will allow for optimal carry on the baseball.
Launch Angle - The angle at which the ball leaves the bat in reference to the ground. 0 degrees of launch angle means the ball is leaving parallel to the ground. Most line drives are in the 12-20 degree range, while most homers are in the 20-35 degree range (depending on how far the ball is hit)
Our guy Frankie hit a 92.8mph laser in the gap with perfect backspin and 1600 RPMs, nice work Frankie!
