With the MLB's playoffs in full swing, player injuries are more amplified than they are at any other point in the season, and the Ziel M2 is a baseball training tool designed specifically to prevent pitching injuries.
Considering that the majority of big league pitchers need to be able to a throw a fastball 95 miles per hour or faster, it's no surprise that pitchers are getting elbow surgery at a higher rate than ever before. Rather than getting the corrective Tommy John surgery, though, the Ziel M2 aims to prevent arm stress in the first place.
The wearable looks just like a compression sleeve, but it's loaded with sensors that monitor pitchers' arm movements. It then uses that data to show pitchers how to adjust their motions to reduce stress and prevent injuries.
