Am I throwing hard enough?

I am almost 15, will be a few days before baseball starts. I weight a little under 130 and I am 5’4”. I was gunned in at 74 mph a couple months ago but due to olympic weight lifting, and CrossFit, I would say ive added a good 3-4 mph at least. My question is should a freshman my size be throwing harder?

Running……?

My fastest mile is 7 minutes and 30 seconds. I stretch and all that, BTW I use a treadmill. Any ways on improving my speed on the treadmill to 5.59 and below minutes. Whoever gives the advice that helps me to 5 minute mile will have their name included on my youtube video of me running that mile. I want to improve my lower body strength because I have REALLY strong upper strength but medium strength in legs, I gotta run fast for baseball in highschool. Any advice?
