Pitchers at all levels of the game are told to locate their pitches in the bottom half of the zone so they can get hitters to swing over the top of the pitch and produce ground balls. As everyone knows, ground balls are the best way to prevent runs, since you can’t hit ground balls over the fence and it’s tough to hit them into the gaps for extra bases. Apologies to all coaches of youth, high school, and many college pitchers, but: You’re wrong. Pitchers should locate their fastballs and breaking balls in the top half of the zone to get the most success when competing against average youth, high school, and most college hitters.
Ground Balls: Be Careful What You Wish For
It’s happened to everyone – including me – you get a ton of ground balls, your defense boots the ball around, you end up giving up 1 or 2 earned runs but a plethora of unearned runs. When your coach comes and pulls you from the game, he says: “Nothing you could have done, kid. Defense just didn’t play behind you,” pats you on the butt, and tells you to get your running in.
Your teammates apologize for booting that easy ball in the hole, for not picking that ball at first base, and dropping that easy double play opportunity. Being a good teammate, you say “Ah, it happens. Get ‘em next time.” Then while running your poles, you reflect on how particularly unlucky you were that day. If only Bobby hadn’t lost that ball in the sun and Roger didn’t sail that ball from shortstop, you would have gotten out of that long inning. But were you unlucky? Think about it: You did everything you were supposed to – get a few strikeouts, not walk too many, and got a lot of ground balls. And what were you rewarded with? Hasn’t this happened before? What if you got fly balls instead? Don’t hitters swing and miss on your fastballs up in the zone – and when they make contact, don’t they often go for fly ball outs? How many home runs does the entire school have, anyway? Four? But what’s the team batting average – .380? Here are the two major reasons you want to get ground balls at the MLB level:
- Sluggers often hit fly balls over the fence.
- Defense at the MLB level is insanely elite.
Think about those reasons for a minute. Do either of those reasons apply to your high school league? What do you think the average HR rate on fly balls is in your league? I guarantee it’s not 11%. (MLB Average HR/FB rate.) We’ve already established defenders at the HS/College level are orders of magnitude worse than the Dominican and Venezuelan infielders of MLB (to say nothing of the local product), so why are you applying a heuristic to a completely different game?
Tons of data and a shattered myth after the jump…
