In the study, 347 pitchers were assessed for lumbopelvic control during spring training. Pitchers with more tilt in their pelvis as they raised a leg to step up were up to three times more likely to miss at least 30 days – cumulative, not consecutive – during the season than were pitchers who showed minimal tilt in their pelvis.  They found that professional baseball pitchers with poor core stability are more likely to miss 30 or more days in a single season because of injury than are pitchers who have good control of muscles in their lower back and pelvis.
