The 16-Year-Old Pitcher: What to Work On

Sixteen is the year before the recruiting clock starts and the age when velocity climbs fastest. Here's how to use it well, and protect the arm doing it.

Quick answer

At 16, a pitcher should turn his strength into velocity, command three pitches to both sides of the plate, get recruiting-ready before junior year if college is the goal (a recruiting video, honest numbers, and research on fits), and protect his arm more carefully than ever as velocity and workload climb. Most 16-year-olds throw around 70 to 80 mph.

Sixteen is a turning point. Most pitchers are sophomores or juniors, the body is close to its adult frame, and if college is on the radar, the recruiting clock is about to start for real. It’s also the age when velocity climbs fastest, and when the arm is asked to handle the most force it ever has.

Here is what a 16-year-old pitcher should work on, in plain English, so this year sets up the next two instead of putting them at risk.

“At 16, the goal is to arrive at junior year with velocity, command, and a healthy arm. All three, not two out of three.”

The pitcher who shows up healthy has options. The one who doesn’t, doesn’t.

What to focus on at 16

Velocity: where the work pays off

Most 15 and 16-year-olds throw somewhere around 70 to 80 mph, and some climb well past that over the next two years. Sixteen is often when a pitcher who did the boring work (strength training, a cleaner delivery, a sensible throwing program) sees it show up as real velocity. Our guide on how to throw harder in high school covers the levers.

For context on what the next level looks like, our guide on how hard you need to throw to pitch in college has honest ranges by level. Use it as a map, not a verdict. Plenty of pitchers add their most velocity between 16 and 19, and compare him to himself, not to the kid on Instagram.

Command: the separator as hitters improve

At 16, plenty of pitchers can throw hard enough to compete. Fewer can put the ball where they want it. Locating the fastball to both sides of the plate is a big part of what makes a pitcher useful to a high school or college coach, and the glove side is usually the harder half. Our guide on glove-side command covers how to build it.

The breaking ball should be a pitch he can throw for a strike when he’s behind in the count, not just a chase pitch. If it isn’t there yet, more reps in bullpens with a target beat adding a fourth pitch.

Recruiting: get ready before junior year

For most pitchers, the real recruiting window is junior and senior year, and NCAA rules generally limit when coaches can start talking with recruits until around the start of junior year (rules vary by division and change, so check the current ones). That makes 16 the year to prepare, so he’s ready when the door opens. Our recruiting timeline for pitchers walks through it.

Protect the arm hardest now

This is the stretch when many serious elbow injuries in young pitchers show up, because velocity is climbing and workloads are stacking: high school season, a summer team, showcases, fall ball. The usual culprits are too many pitches, too little rest, pitching while tired, and too many months of the year on the mound.

Pitch Smart guidelines set a 95-pitch daily maximum for 15 and 16-year-olds. Count across every team, take a real break from pitching each year, and be especially careful with showcases, where kids max out for a radar gun on an arm that may already be tired. Never trade a healthy arm for a number. If his elbow or shoulder hurts, he stops and you see a doctor. Our guide on Tommy John surgery in young pitchers explains why this matters so much.

The bottom line

A 16-year-old pitcher should turn his strength into velocity, command three pitches instead of just throwing them, get recruiting-ready before junior year if college is the goal, and protect his arm more carefully than ever as velocity and workload climb. The pitchers who come out of 16 in the best shape arrive at junior year with real numbers, a clean video, and a healthy arm. Little things now, big numbers later.

Common questions

What should a 16-year-old pitcher work on?

Turning strength into velocity, commanding three pitches to both sides of the plate, getting recruiting-ready before junior year if college is the goal (video, honest numbers, research on fits), and protecting his arm as velocity and workload climb.

How hard should a 16-year-old pitcher throw?

Most 15 and 16-year-olds throw somewhere around 70 to 80 mph, and many keep adding velocity through 17, 18, and beyond. Growth and strength timing still vary a lot, so his progress over time matters more than any single number.

Is 16 too late to get recruited as a pitcher?

No. For most pitchers, recruiting happens junior and senior year, and NCAA rules generally limit when coaches can start talking with recruits until around junior year. Sixteen is the right time to prepare: a recruiting video, honest numbers, and a list of programs that fit.

How many pitches can a 16-year-old throw?

Pitch Smart guidelines set a daily maximum of 95 pitches for 15 and 16-year-olds, with rest days required after higher counts. Count pitches across every team and event, including showcases, and treat the limit as a ceiling.

Should a 16-year-old throw a slider?

It can be reasonable at 16 if he already commands his fastball and changeup, has clean mechanics, and is coached on it. A breaking ball he can throw for strikes matters more than how many pitches he has, so master one before adding another.
