Everyone is talking about swing decisions.
But almost nobody is actually training them.
Introducing the Marv Sunken Seam Dimple Ball.
When paired with the Original Sunken Seam, hitters get the ultimate decision training environment.
Same velocity.
Different location.
No machine adjustments.
The hitter can’t tell the difference out of the machine.
Example training sequences:
• Original – hanging slider (GO)
• Dimple – slider down & away (TAKE)
• Dimple – thigh high fastball (GO)
• Original – below the knees (TAKE)
Hitters learn to:
✔ Hunt go zones
✔ Control the strike zone
✔ Make real swing decisions
Works with all pitch shapes.
If you’re serious about improving swing decisions…
This is how you actually train them.
