Yes it is possible. If you have a very intense workout and do a lot of work on mechanics and maby longtoss and/or yoga, whatever works best for you it's very possible.
From what I see you are 13, correct?, and I don't believe you should be on an intense workout scedule to try and gain certain MPH. Your still growing let your body do some of the work. I'd do tubing and maby some longtoss just not too much intense workouts.
Some will come naturally but most you will have to gain yourself but at your age you should wait a year or two.
