im a sophomore going on to my junior year, im mainly a catcher but pitch some in a closer role for my high school team and start some games for my summer league teams.  I throw: 
 
4-seam - mid 70's at best 
 
2-seam - mid 70's with downward movement, more like a sinker 
 
Split-finger change- good, late movement into a righty (my out pitch) doesnt work as well when its humid outside cuz it tends to stick to my fingers and doesnt get enough spin 
 
Slider/Slurve- 10-4 movement on good days when i can control it 
 
Knucklecurve- dont really use this one alot cuz im just learning how to throw it correctly 
 
I also mix in a cutter here and there to change things up
