My 12 year old Little League son is about 5’-11" and 165 - 170# and throws somewhere in the 70s. He was at 70 last year and throws considerably faster this year. He’s also grown 4" since last summer. He throws a 2-seam fastball that moves in on the RH hitter, a slider that moves down and out, working on a circle change that his coach says is getting there, and a knuckle curve that drops down. He practices at the High School and can’t wait to move up to the bigger field so he can use all of his pitches.
It’s “unfair” for him to play in Little League, but he’s still 12 and is having fun being a kid. He loves his teammates and they love him. In 12 innings so far, he has 36 strike outs and 3 walks. He started a new pre-game warm-up yesterday. Throws the heater on the 1st warm-up pitch, then the slider, change and knuckle-curve; fastball, slider and change. By then the entire opposing team has freaked out, and it’s an easy 1-2-3. He’s very intimidating on the mound at this age.
