here's my deal...
As a HS Junior
4-seam 86mph
2-seam 83mph
Changeup about 70mph
Curveball about 70mph
Senior year
4-seam 84mph
2-seam 80mph
Changeup 70
Curveball 70
Slider 74
What happened?
Too many curveballs early in my HS years screwed my elbow and I lost 2 months of training in the off-season and 3 weeks during the season to rehab instead of surgery.
I got up to 86mph on my 4-seamer my Freshman year in college but got cut because I was signed as a starter and couldn't throw 7+ innings in a game without having to go 7 days between starts because of arm pain.
I had a brief stint as a reliever throwing about 85mph sidearm with great movement, but by the time I was seeing success that way I was 22 years old, and these teams already had 18 year old lefties throwing 90.
Needless to say I regret not learning a better changeup and staying away from the curve a little while longer...
