I don’t know your age, but I wouldn’t try to integrate a knuckleball into your repertoire. I would stick with more conventional pitches: fastball (2 and 4 seamer), change-up, curveball, or slider.
Most youth league pitchers think they have a knuckleball because they can throw a pitch that has very little rotation. What they don’t realize is that the only thing probably making that pitch effective (if at all) is its offspeed nature, not that it dances and tumbles like Tim Wakefield’s knuckleball. They’d probably have the same type of success with a conventional change-up.
I’ve seen a lot of kids who think they have a knuckleball, but they really don’t. All it does is come in straight, slow, and with little spin.
I also don’t know what kind of aspirations you have for the future - but most scouts and colleges are not looking for tricky knuckleballers.
There’s a reason that this pitch is rarely thrown in the higher levels of baseball.
You either have a great knuckleball or you don’t. Most pitchers that have a great one are knuckleball pitchers (ala Tim Wakefield). It’s what they throw 95% of the time. They don’t care if the batter knows it’s coming. They do not rely on the element of surprise, instead, they rely on the fact that the pitch is so random, it is difficult to make solid contact. It’s like playing wiffle ball on a windy day.
Unless your knuckleball has a lot of movement, I’d put it on the shelf and focus on your more conventional pitches. Work on improving your mechanics and try to get your fastball faster. If you could achieve that simple goal, you’ll find your other pitches (change-up and curveball) start becoming more and more effective.
The knuckleball is an “old man” pitch -or- a pitch that pitchers resort to once they discover they have a great one and that they have had little success with more conventional techniques. There are very few knuckleballers who started off as knuckleballers. They evolved into a knuckleballer out of necessity.
