I pitched at a pretty high level and threw hard enough to get scouted by the sox and other organizations. I can say from experience with a multitude of lesser injuries that the worst of them all IMO was a back or oblique strain. I couldnt finish my pitches. Everything was up. And the only way I knew my pitch would stay down was if it hurt. If you dont finish your pitches, everything stays high. The curveball has the same break but ends up down the middle instead of at the knees. The heater is chest high and ready for a homer. Those were the days I'd throw a lot of pitches inside. Since everything stayed up, no batter wished to dig in since a lot of the pitches where I missed location went whizzing by their helmets. I didnt have much trouble with lateral movement more than my usual wildness. But as I went on with my college career and had capable rotation mates, I would usually skip a start. I only had to skip a couple, but it becomes difficult to strike the fear of god into hitters as they become more advanced.
