My son pitches, and for two years our side sessions depended on me being home, which meant they happened about half as often as they should have. Then we figured out what can genuinely be trained alone with a net, and the frequency problem disappeared. Not everything transfers. But more of it does than most people think.
Be Honest About What You Can't Do Alone
You can't get a real read on pitch movement without a catcher or a camera setup. You can't simulate a batter's timing, and you can't practice holding runners. If a coach tells you a solo net session replaces a bullpen, they're selling something.
What you can do is build the mechanical foundation and location habits that make real bullpens productive. That's a bigger deal than it sounds, because most young pitchers waste their catcher's time fighting their own mechanics.
What Actually Works
Strike zone accuracy, with a score
This is the highest-value solo work available. The $55.55 nine-hole pitching net gives you nine specific targets instead of one vague rectangle, which turns location practice into something you can measure. I have my son call out which hole he's aiming for before every throw, and we keep a tally out of twenty. Same aim, wrong hole still counts as a miss. That's the standard that transfers.
Without a target grid, pitchers unconsciously aim at the middle of whatever they're throwing into, which builds exactly the habit you spend years trying to break.
Sequence games
Nine holes means you can rehearse sequences instead of single pitches. Fastball low and away, then changeup off the same slot, then fastball up. Call the sequence out loud, execute it, and score it. This is the closest a solo session gets to game thinking, and it costs nothing but discipline.
Mechanical reps at seventy percent
Nobody throws full effort into a net alone for twenty minutes. But arm path, hip direction, and front-side stability all show up clearly at seventy percent intent, and the lower intensity is exactly what makes fifty reps possible without wrecking an arm.
Setting It Up So The Reps Count
- Distance matters. Standing at full mound distance into a net turns every throw into a long toss. For location work, forty-five to fifty feet gives realistic release timing with less wear.
- Same spot every time. Tape a line for the rubber so your setup is repeatable. A pitcher who drifts three inches between throws isn't practicing location, he's practicing adaptation.
- Log the misses, not just the hits. The pattern of misses tells you more than the total. Consistently high and arm-side means something, and you'd never see it without writing it down.
- Use the other half of the household's gear. Our $69.99 premium net with the adjustable tee handles both sides of the family — I hit off the tee while he throws into the nine-hole net, and one setup covers a full hour.
A Twenty-Five Minute Solo Session
- Warm-up and band work, five minutes, no ball.
- Fifteen throws at seventy percent, fastball only, focused on arm path.
- Twenty throws at target holes, called out loud, scored out of twenty.
- Ten throws as three called sequences, mixed pitches.
- Five minutes of flat-ground work or towel drills to finish.
What The Frequency Change Did
Two sessions a week became four or five, because the net doesn't need a partner and doesn't need scheduling. His location score went from around twelve out of twenty to seventeen over about six weeks, and his actual bullpen sessions got shorter and sharper because he wasn't using them to fix mechanical drift anymore.
If your pitcher is stuck waiting for someone to catch for him, stop waiting. The net won't replace a catcher, but it will make the sessions you do get worth a lot more.
