How to Cut Chase Rate by Fixing the Feet: The Anchor-the-Base Drill

Ask a coach why a hitter chases and you'll usually hear "he's not seeing the ball" or "she needs to be more patient." Sometimes that's true. But a huge share of chasing is mechanical, and it starts below the belt. When a hitter's weight leaks forward early — a stride that drifts, a front heel that never plants, a lunge toward the pitch — the barrel gets pulled into the zone whether the pitch belongs there or not. By the time the eyes register a low curveball or a fastball off the plate, the body has already committed. That's a chase.

The Anchor-the-Base drill attacks that root cause directly. Instead of asking a hitter to "be more disciplined" (an outcome, not a skill), it isolates the lower half so the hitter learns to land the stride, stick the front foot, and hold the base underneath them. A quiet base buys time. Time lets the hitter see the pitch. Seeing the pitch lets them take the ball. The measurable payoff is a single number: chase rate, the percentage of out-of-zone pitches the hitter swings at.

Why chase rate is worth training on its own

Chase rate is one of the cleanest windows into hitting performance we have. Pitch-tracking research and public data from Major League Baseball's Statcast show that swinging at pitches outside the zone produces dramatically worse contact and results than swinging at strikes — out-of-zone swings generate more whiffs and far weaker contact. Driveline Baseball's plate-discipline work makes the same point at the amateur level: the hitters who control the strike zone get into better counts, see more hittable pitches, and do more damage. Lowering chase rate raises on-base ability and slugging at the same time, which is why it deserves a dedicated drill rather than a passing reminder.

MLB hitters chase roughly a quarter to a third of out-of-zone pitches; youth and high-school hitters are typically higher, often well above 35–40%. That gap is the opportunity. And because chase rate is a rate, you can track it in a single practice round and watch it move.

The mechanics: chasing lives in the front foot

Here is the mechanical story coaches should internalize. A good swing decision requires the hitter to keep options open as long as possible — to be able to swing OR take right up until the last instant. The lower half is what preserves that option. If the front foot lands soft, quiet, and on time with the heel down and the back knee stacked, the hitter has a stable base to either fire from or hold from. If the front foot drifts, lands late, or the heel floats, the hitter's center of mass is already traveling forward, and a body in motion wants to finish the swing. Momentum makes the take physically expensive, so the hitter chases.

That's why we isolate the feet. We are not asking the hitter to think harder about pitches. We are removing the mechanical thing that steals their choice.

How the drill works

Set up a pitch source that can throw to a plan — a machine, or a coach doing front toss from behind an L-screen. Mark the strike zone clearly with chalk or two pool-noodle uprights at the plate edges so the hitter and the person tracking agree on what's in and out. Place a stride pad (a folded towel, a flat agility dot, or a taped line) where the front foot should land. That pad is the whole point: it gives the front foot a target and a reason to stay quiet.

Before each round, the feeder secretly scripts a mix of about 60% strikes and 40% clearly out-of-zone pitches — mostly below the zone and off the edges, the pitches that should be taken. The hitter doesn't see the script.

On every single pitch, the hitter does the same first thing: load, take a slow controlled stride, and stick the front foot on the pad with the heel down. Only after the base is anchored do they read the pitch. Strike? Finish the swing off the quiet base. Ball? Hold — and because the feet never committed, holding should feel effortless. A tracker counts every out-of-zone pitch fed and every out-of-zone swing, and chase rate falls out of the math: out-of-zone swings divided by out-of-zone pitches.

The cue that ties it together is "Land, then decide." Separating the stride from the swing decision is the skill the drill builds.

Fitting it into practice

Anchor-the-Base is a 20-minute station that slots into any hitting block, in-season or off-season. Because the movement load is low — it's controlled swings and stride reps, no max-effort exposure — it's safe for hitters from about 12U up, once they have enough pitch-recognition to distinguish a clear ball from a strike. Younger or newer hitters can start with pure freeze reps (stride and stick, no swinging) until the base is reliable.

Use it early in a session when the hitter is fresh, since it's a focus-heavy skill. Rotate three or four rounds, re-scripting the feed each time so the hitter can't pattern-match the sequence. Pair it naturally with a two-strike approach block or a count-leverage drill; discipline compounds.

How to progress it

Start with freeze reps — all takeable balls, no swings — until the front foot is quiet every time. Then move to the take/drive game with the scripted mix and a chase-rate goal. When the base holds there, shrink the timing window: go from front toss to machine velocity at game speed, then add a firm off-speed pitch that dives below the zone, which is the single most common chase pitch in a real at-bat. Finally, remove the stride pad and run the same take/drive game without the constraint. If the quiet base survives and chase rate stays low, the mechanic has transferred.

A reasonable success standard: over a scripted round of 15–20 pitches, the hitter chases no more than 20% of the clearly out-of-zone pitches while still driving the strikes. Track the number round to round and let the hitter see it drop — nothing motivates plate discipline like watching a real metric move.

The bottom line

Discipline isn't a personality trait you nag into a hitter. It's a skill built on a stable base. Fix the feet — quiet the stride, plant the heel, hold the anchor — and the takes take care of themselves. Anchor-the-Base gives you a repeatable, measurable way to do exactly that, with chase rate as the scoreboard.
