Bullpen Report | Youth Baseball Pitch Count Tracker

TL;DR: Cold weather means a longer warm-up, not a shorter one. A solid pregame routine takes 20–30 minutes: get warm with general movement, run a band series, work through progressive catch and long toss, then finish on the mound. Keep his arm covered between innings, save static stretching for after he throws, and keep plyo balls to light drill work. Max-effort weighted ball programs can wait until he's done growing.

A few weeks into fall ball, most pitchers have a handful of outings behind them and the season is starting to feel routine. That's exactly when warm-ups get rushed. Add 40-degree night games and early-morning tournament starts, and you have the combination you want to avoid: an arm that's already carrying a season's worth of work, going to the mound before it's ready.

Why Cold Weather Changes the Warm-Up

Warm muscles and tendons stretch and absorb force better than cold ones. On a cold night, it simply takes longer to get the shoulder and elbow loose, and the usual 10 throws on the side before the game don't get the job done.

Cold weather also changes behavior. Kids stand around longer in the dugout, throw fewer warm-up pitches to get out of the cold faster, and sit through long half-innings with their arm cooling off. The first inning after a long wait is often when an arm is least ready and working hardest.

A 20–30 Minute Pregame Warm-Up for Youth Pitchers

This is a simple, repeatable routine that works for most ages. On cold days, stretch each step toward the longer end rather than cutting anything.

Step	Time	What it looks like
1. Get warm	5 min	Light jog, jumping jacks, arm circles, walking lunges, trunk rotations. Aim for a light sweat before he picks up a ball.
2. Band work	5 min	J-Bands or any light resistance band: internal and external rotation, forward and reverse flys, 10–15 controlled reps each.
3. Plyo drills (optional)	3–5 min	Light balls, sub-max effort only: reverse throws, pivot pickoffs, rocker throws into a wall.
4. Progressive catch	5–10 min	Start at 30–45 feet and back up gradually. Easy effort first, building intent as the arm loosens.
5. Long toss	5 min	Arcing throws out to a comfortable distance, then shorter, firmer throws on the way back in.
6. Mound work	5 min	Fastballs first, then off-speed. Build to game intensity by the last few pitches.

J-Bands and resistance band work

Band work wakes up the small muscles around the shoulder blade and rotator cuff that stabilize the arm through the throwing motion. The point is activation, not a workout: light resistance, slow and controlled reps, no burning. If he does his band series at home on off days too, it becomes part of his routine instead of something he skips when he's running late to the field.

Plyo balls: light drill work only

Plyo balls have become a standard part of a lot of warm-ups, and light, controlled drill work (reverse throws, pivot pickoffs, rocker throws into a wall) is a common way to groove arm action before catch play. The line to draw is effort level. Max-intent weighted ball velocity programs are a different thing, and the research on them is a caution sign for young arms.

In a 2018 study of high school pitchers, 24% of the pitchers on a 6-week weighted ball program were injured, compared with none in the group throwing regular baseballs. Velocity went up too, which is exactly why these programs are tempting. The common recommendation is to save overload velocity work until a player is physically mature and has a strength foundation under him.

Long toss: stretch it out, don't max it out

Long toss builds arm strength and gets the arm fully loose, but on a cold night it's not the time to chase his max distance. Let the throws arc, back up only as far as he can go while staying loose and on line, and then come back in with shorter, firmer throws. If he's grunting to reach his partner, he's too far out.

Between Innings on Cold Nights

Jacket on the throwing arm, every time. The arm cools fast sitting in the dugout.
Keep moving during long half-innings. A few arm circles and band pulls in the dugout beat sitting still for 15 minutes.
Play catch before going back out after a long wait. A handful of easy throws before he heads to the mound gets him back to where he left off.
Don't rush the between-innings warm-up pitches. Use all of them, even when everyone wants to get the game moving.

Stretching: Dynamic Before, Static After

Before throwing, stick with movement: arm circles, lunges with a twist, leg swings, trunk rotations. Save the longer, hold-it-for-30-seconds stretches for after he's done throwing, when his muscles are already warm. A few minutes of light band work and gentle stretching after the game is a good habit to build now.

Arm Care Between Outings

The warm-up protects him on game day. What happens between outings keeps him healthy across the whole season:

Respect the rest days. Required rest is based on how many pitches he threw. See the full rest-day chart.
Count every team. If he pitches for more than one fall team, rest and pitch counts carry across all of them. Here's how to track it across a tournament weekend.
Keep up band work on off days. Light, consistent, a few minutes at a time.
Know the difference between sore and hurt. General muscle soreness the day after pitching is normal. Pain on the inside of the elbow, pain that sticks around, or a sudden drop in velocity or control means shut it down and have him seen by a sports medicine professional. Why overuse is behind so many youth elbow injuries.

Make the Routine Stick

The hardest part of arm care isn't knowing what to do. It's doing it every time, especially when it's cold and he's running late. Writing the routine down helps, and so does tracking it. Bullpen Report lets you log daily arm care routines alongside every outing, so you can see his streaks, his workload, and his rest days in one place, across every team he pitches for.

FAQ

How long should a youth pitcher warm up before a game?

Plan on 20 to 30 minutes before he throws his first pitch in the game: a few minutes of general movement to get warm, a resistance band series, progressive catch play that stretches out into long toss, and then mound work. On cold days, lean toward the longer end.

Should youth pitchers warm up longer in cold weather?

Yes. Cold muscles are stiffer and take longer to get loose, so a cold day calls for a longer, more gradual warm-up, not a shorter one. Get a light sweat going before he picks up a ball, build up throwing distance slowly, and keep his arm covered between innings.

Are plyo balls safe for youth pitchers?

Light, controlled plyo ball drills are commonly used as part of a warm-up. Max-effort weighted ball velocity programs are a different story: in a 2018 study of high school pitchers on a 6-week weighted ball program, 24% of the weighted ball group was injured versus none in the control group. Most experts recommend saving those programs until a player is done growing.

Should pitchers stretch before or after throwing?

Both, but differently. Use dynamic movement before throwing (arm circles, lunges, trunk rotations) to warm up, and save longer static stretches for after throwing, when the muscles are already warm.

This article is for general educational purposes only and is not medical advice. It isn't a substitute for guidance from a physician, athletic trainer, or physical therapist who knows your player. Every athlete is different, and warm-up, arm care, and training programs should fit his age, development, and health history.

If your player feels pain while throwing, has elbow or shoulder pain that doesn't go away, or shows signs of injury such as swelling, numbness, tingling, or a sudden loss of velocity or control, stop throwing, rest, and see a qualified medical professional before he returns to pitching. Pitch count and rest-day guidelines are minimums, not guarantees against injury.
