Wow, this is the first time I've heard this. I can't wait to share that article with my husband. We've been of the "it's a natural motion" mindset for years. We have a 13yo pitcher, thankfully the team she's on now has a great pitching staff of 4. Thank you so much for getting the word out, I'm so thankful I found this now, I know it will make a difference in her future.
We were at a tournament in the summer with our 15yo daughter (not a pitcher), the team was down to one pitcher (the only other one was injured). The girl pitched five games in one day, then another one first thing the next morning. We were SSOOO impressed that she could do that...everyone was. We were so proud of how well the team did under the circumstances. Not once did we hear anyone talk about overuse. I will share that info with her parents, and the coaches, in the hopes they never let that happen again.
Thanks again, this is valuable info!
