Flamethrower,
80 is good for a freshman.
People sometimes get confused by the words physical projection. It's more about physical maturity than it is about present size.
For example, it's possible that the 5'8 player is very mature physically and the 6'1-6'2 player has not even started to mature. In this case the 5'8 player could maybe grow another inch making him 5'9. The 6'1 player might grow another 6 inches before he is physically mature making him 6'7.
The same thing holds true for velocity to a certain extent. The smaller more mature guy is less likely to gain as much velocity compared to the taller physically immature guy.
The fact you mentioned you haven't hit your growth spurt yet bodes well for your future. But even if you don't grow as much as you hope... you can still be very good and very successful. Best of luck!
