I wanted to see if Betancourt's struggles this season were because of any changes in his mechanics, so I pulled up his info from Josh Kalk's website to find out. I also looked for any changes in his pitch selection, velocity, and K/BB rates.
I think the fact that Betancourt's using his fastball less and trying to use more secondary pitches is kind of screwing him up. His slider has lost a lot of it's bite from last season, yet he's using it more often. His fastball velocity has held steady, but there isn't as much vertical movement on it. I was surprised to see his arm slot is pretty much the same though.
I think he may also be working around some back issues (hadn't heard that until recently) which have caused him to change his delivery some. It's almost as if he's fighting against a learning curve in making these adjustments, hence the poor outings this season.
I was curious what you guys thought of the Pitch f/x part. This is the first time I've used any of it in depth, so if you notice any errors of poor interpretations, I'd certainly be open to feedback there.
