I Tried to Prove Pressure Beats Power

I have carried a hunch for years. Swing and miss is a waste. Put the ball in play and you create pressure. Pressure makes the other team crack. Nobody talks about it because you cannot measure it.

So I tried to measure it. I lost the argument. That turned out to be the useful part.

The test

Three full MLB seasons, 2024 through 2026. Twenty-five teams with complete data, 75 team-seasons in all. I defined pressure as things a team can mostly control:

• Traffic. Runners the defense has to deal with. Hits that are not homers, plus walks, hit by pitch, and reached on error, per plate appearance.
• Fast traffic. Stolen bases.
• Aggressive traffic. Taking the extra base. First to third, second to home.

Then I lined each one up against runs and wins, and against plain power: home runs.

What survived: traffic

Runners on base drive runs. Not fast runners. Not aggressive runners. Just runners.

Put in plain numbers, a team that steals about 35 more bases a year gains roughly 7 runs. Less than one win. A team that climbs a similar step in traffic gains roughly 39 runs. About four wins. That conversion uses the common rule of thumb that about 10 runs equals one win, so treat it as a ballpark, not a measurement.

What did not survive

Pressure does not beat power. Once I accounted for pitching, traffic and power tied. Both matter. They are also unrelated to each other, which means they are two different ways to win, not one thing measured twice.

Pressure does not make big league defenses crack. If it did, aggressive teams would reach on errors more often. They do not. A team's error rate barely repeats from one year to the next, which looks like luck, not skill. At this level it happens about once every five games. The fielders are just too good.

One honest caveat. Errors are a scorer's judgment. Some pressure may hide inside plays scored as hits. This data cannot see that.

So I rebuilt Moneyball

Get on base. Do not give away outs. Stolen bases are worth less than they look. That is the core of what the 2002 Oakland A's figured out, written up by Michael Lewis twenty years ago. Economists later checked it and found the market really had underpaid on-base skill at the time (Hakes and Sauer).

So I found nothing new about the big leagues. The newer bit is that it still held after the 2023 rule changes, with bigger bases and a pitch clock. Running did not become the answer.

Why it still matters at 10U

Here is the turn. I am not trying to win a pennant with nine-year-olds. Our job is to make them want to come back tomorrow.

At this age, putting the ball in play is not mainly a winning strategy. It is an action strategy. More balls in play means more touches, more reads, more chances to do something and see it matter. That is the stuff that keeps a kid in the game.

And youth defenses are not big league defenses. One PONY league coach tracked his son's games for years and published the numbers (Golton). On his 9 and 10 year old rec team, about 1 plate appearance in 17 ended with the batter safe on an error. In the big leagues it is about 1 in 170. That is roughly ten times the chances. In his coach pitch seasons, the team with the fewest errors usually won.

That is one coach in one league, not a study. But it points the same way. If balls in play force mistakes anywhere, it is at 10U.

What we are taking from this

• Get on, stay on. Traffic is the engine.
• Swing to put it in play. At 10U it buys action, and action buys fun.
• Run hard, but do not overrate it. Speed on the bases is a garnish, not the meal.
• Test your own hunches. Losing an argument to the data is still a win.

Next practice: the Traffic Game

The whole lesson in one scrimmage. About 15 minutes, any age that plays live.

• Small sides. Two teams of four to six. Half the field. Coach pitches or a kid pitches, whatever your league plays.
• New scoring. The offense scores one point for every runner who reaches base. Hit, walk, hit by pitch, error, dropped third strike, all the same. A runner is a runner.
• Runs are a bonus. A runner who scores is worth one more point. But the first point comes from just getting on.
• Defense scores outs. One point per out. Three outs and switch.
• Two strikes, new job. With two strikes, a ball in play earns a point even if it is an out. A strikeout earns nothing.
• Huddle for 20 seconds. “Who got on base today? How?” Let them list the ways. Then move on.

Note on certainty: this is a coach's test, not a peer-reviewed study. Five of 30 teams were missing complete data. Results are correlations within each season; the pitching control strengthens the traffic finding but does not prove cause. The youth-ball claims are a coach's hypotheses, not findings.
