A rotator cuff tear happens when there is a swift tear in the joint. In Matts case, when he tried to pitch the baseball as fast as he could he tore his rotator cuff in his right shoulder. In most cases in which throwing is involved, the tear happens once the arm is slowing down rather than speeding up. (Sports Injury Clinic) The muscles involved in the rotator cuff are the supraspinatus, infraspinatus, teres minor, and subscapularis. (Sports Injury Clinic) The muscle that is most often torn in a rotator cuff injury that involves throws is the supraspinatus. The supraspinatus muscle is located in the supraspinatus fossa, in the shoulder or the glenohumeral joint. The supraspinatus muscle allows the commencement of horizontal abduction, which allows upward movement of the arm. (Team) The infraspinatus works with the teres minor to rotate the glenohumeral joint and secure the shoulder. (Goel) The teres minor laterally helps the rotation of the arm at the glenohumeral joint, or the shoulder. The teres minor can also be of assist by abducting the arm at the shoulder and stabilizing the shoulder. (Smart) Last, but not least, the subscapularis muscle works to stabilize the glenohumeral joint and allows the shoulder to turn inward. (Team) The supraspinatus, infraspinatus, and the teres minor insert at the greater tuberosity, while the subscapularis inserts are the lesser tuberosity. (Pictures) As far as treatment options go, depending on the size of
