I feel like...

I'm glad you posted, wildcats.  There are some on this board who believe there is a place for anyone who wants to play college bad enough.  The fact of the matter is that with your current skill set, it would likely be near impossible to make someone's roster. 

Now the good news...  You have two years left and you seem to have the desire and initiative.  It is certainly not out of the question that you could work yourself into a player who does have a chance.  I don't recall what kind of student you are but it is extremely important to put grades on the same high pedestal that you have put with your efforts to improve your game.  Particularly for someone like yourself, good grades will ultimately afford you exponentially more options than mediocre grades... so many D3's are high academic and only feasible with good grades.  And many of these schools are likely to be better fits with baseball. 

Don't feel rushed but feel urgency and a need to consistently commit to the effort.  Every individual is different (we don't even know how you play outside of the numbers you have provided) so none of us can promise that you can work your way into someone who can make it in college but it's certainly possible and you do have time.  Realize that some of the D3, NAIA and JC recruiting efforts occur quite late, even after graduation in some cases.

If you don't find that you're getting interest from college coaches while in HS, you might keep in mind (particularly that baseball sounds very important to you) there's always JC's that offer opportunities to play college ball and if you do well enough there, doors can open to other colleges where you can be pick up.... even for D-1s.  So, baseball doesn't have to end at HS if things are working out well there for you for what ever reason.

Theres a trickle down effect to recruiting. This means D3 players typically won't be recruited until the summer and fall after junior year. You have another year to develop before it's showtime. Do e work to get stronger and increase velocity. You have the advantage of throwing left handed. Get to 80+ and throw strikes with your fastball and an off speed pitch.

I want to echo what RJM and Truman said. Yes the velo isn't there but you can do some things. Keep long tossing!! And keep backing up. Try to get to 300 ft and chart it. Keep track and be consistent. If you don't have a partner just get a bucket of balls and do it yourself. But keep doing it! There is no secret to velo but Long toss is the closest thing I've seen that actually works or helps for incremental velocity increases. Lots of long toss info online. Stay with it and the band work. Learn about Alan Jaeger and what he is trying to do. Go to youtube and search Alan Jaeger.

Also, check your stride. When you break your hands you gotta step that front leg WAY out front. Stride length adjustments ( longer) can have an impact on Velo. Get a piece of chalk go on your driveway and do your windup / delivery then mark w/chalk where your front foot lands. Then add a foot and make a mark, now do your delivery and land THERE. Then in a few days try to add another foot.

Also, there is no substitute for a good pitching coach. Ask around or go to the nearest University and go to the baseball dept and ask for help. Tell them you are looking for a pitching coach.

You are a LHP. That is a coveted player at the College level. Keep working, get a coach and you will be fine. You are gonna grow and or get stronger. Hang in there and work hard. The guys that play at the next level work their tails off. Get busy!

What others have hinted at, but not really asked, is how tall are you, how much do you weight, what are the heights of your parents?

I'm not going to say this is the typical scenario here, but I know of a guy personally who sat around 75mph in 10th grade....he grew 8 inches and gained 50 pounds by the end of 11th grade.  He said it was the hardest time of his life because he felt like every day he had to relearn how to throw, but while his body changed he worked every day, and he worked hard, and that hard work actually landed him with an offer from a D2 his senior year when he touched 92 at a showcase.  He swears if you had asked him that week if he was throwing 90 he would have said no....for him it was all about timing.   

If you are a 6'5 11th grader and taller than both of your parents then I would focus on the JUCO D3 route if baseball is passion....if you are 5'9 and your dad is over 6 foot I would say you are a late bloomer who needs to work hard and maybe, just maybe, you will bloom in time.  If not, well I hear that is what the JUCO's are for, for the late bloomers to catch up to everyone else.

Good luck!
