Doing both is counterproductive.
When mine was 13, she was also throwing 51 - 53 pretty consistently. In our area, that is on par with quite a few varsity high school pitchers. But getting a TRUE speed of a kid is like trying to get a woman's weight. Fortunately, the NFCA numbers Catching Coach posted are right on par with the research I did when my DD was younger, and are a great resource for accurate, average measurements. DD is now a DI junior, and tops out at about 61. But she didn't gain speed on an even curve. Her gains between 53 and 61 were made from age 13 to 17 - over 4 years period. Now, at 20, she's MUCH stronger, her pitch arsenal is more perfected, but her fastball speed is still a consistent 61. That was enough to get her college education paid for.
I cannot stress enough - DO NOT GET HUNG UP ON SPEED, for speed's sake. Instead, stress PROPER form (excellent mechanics), which will produce pain-free pitching. Use the Greg Maddux approach - less is more. Become a specialist at maybe 3 pitches, like a drop, change and rise. Fastball is a given. The key to being a specialist is PINPOINT ACCURACY. You have NOT mastered those pitches until you can throw them for a strike when needed!
A 65+ mph fastball is driven by genetics. It's NOT a simple matter of "if you train hard and well enough, it will happen". Use excellent training, and maximize the gifts you are given. The rest will take care of itself. Otherwise, you are setting yourself up for some major disappointment.
