Squish the Bug (Back-Foot Action)
Also known as: squish the bug, squash the bug, squishing the bug, back foot pivot, pivot the back foot, back foot action when hitting, what should my back foot do, back heel up when hitting
'Squish the bug' is an old youth cue to pivot the back foot as if grinding out a bug. Many coaches now call it a myth when taken literally, since spinning in place can keep weight stuck on the back leg. A better aim is to push off the back side so the heel rises and the hips turn toward the pitcher.
The cue came from youth coaching as a way to get hitters to turn the back hip. Grinding the back foot does make the hips rotate. Many hitters who squish the bug end up spinning in place, though. Their weight stays back and the barrel loops up under the ball.
Look at strong hitters at contact. The back heel is up, and the back foot is often light or even dragging forward. The back knee drives toward the pitcher. The back foot is a result of the hips and legs pushing. It is not a twist to perform on its own.
The cue can still help a young hitter who has no hip turn at all, for a short time. Pair it with a forward feel, like showing the back pocket to the pitcher. Hitters who already rotate should focus on pushing off the back side and turning into a firm front leg.
Tips by skill level
Finish your swing with your back knee pointing at the pitcher and your back heel off the ground.
Watch your back foot on slow-motion video. A heel that lifts and a foot that unweights as the hips turn shows weight moving forward.
Example
An 8-year-old was told to squish the bug and now spins on her back foot with her weight behind her. Her coach asks her to finish with her back knee pointing at the pitcher. Her weight moves forward, and she starts hitting line drives instead of pop-ups.
Why it matters
The back foot shows where the weight went. Fixing the cue keeps young hitters from learning a spin that robs them of power.
Common mistakes
- Grinding the back foot while the weight stays on the back leg
- Spinning in place and pulling off the ball
- Forcing the back foot to stay planted after contact
- Using the cue for years after the hips already turn
Frequently asked questions
Should I squish the bug?
Not literally. Grinding your back foot can leave your weight stuck behind you. Push off your back leg so your hips turn and your back heel comes up instead.
What should my back foot do when I swing?
It should turn and come up on the toe as your hips rotate and your weight moves forward. Many good hitters finish with the back foot light or dragging forward.
Is it bad if my back foot comes off the ground when I hit?
Not usually. Many strong hitters have the back foot drag or lift as they turn. It is a problem only if you are falling off balance after the swing.
Related terms
- Hip Rotation (Batting)Hip rotation is the hips turning hard toward the pitcher to start the swing. It is the engine of rotational power, firing before the hands or barrel move.
- Back-Side MechanicsBack-side mechanics are how the trail hip, knee, and foot fire in the swing. This "engine" side drives rotational power from the ground up through the barrel.
- Weight ShiftWeight shift is the deliberate transfer of body weight from the back foot during the load to the front foot during the swing, generating forward momentum that adds power at contact.
- Rotational HittingRotational hitting is a swing model powered mainly by hip and torso rotation, not forward weight shift. It is the dominant power model in modern baseball.
- Front-Leg Brace (Firm Front Side)A front-leg brace is the lead leg firming up, often close to straight, as the swing turns. It stops the body's forward move and turns it into rotation. Many hitters land with a slightly bent knee and then push into the ground so the leg is firm by contact. It should not be locked stiff the moment the foot lands.
