I have a 16yr old beginning pitcher, RH. She says her left hip pops when her stride leg lands. She's just beginning so her stride isn't anything ginormous. She told me this after practice the other day so I haven't looked to see if there's anything obvious. I've got 20years in this game but I'm a newbie when it comes to working with pitchers. The only thing I could think of to watch is how her stride foot lands.. if she's near 45* or where it is. I had noticed early on that she would be leaning forward at release and tried to get her body position back farther. So I'm wondering where I need to look in her motion to be able to eliminate this issue. Yes I'm sure you'll want a video, if I get one I'll try to figure out how to post it. Thanks everyone.
