Velocity is great, but spin is what makes a 4-seam fastball truly elite. ⚾🔥 The right backspin keeps the ball on plane, creates that “riding” effect, and makes it way harder to square up. But here’s the key: it has to spin off both fingers evenly for max efficiency. Uneven release? You’ll lose ride, add unwanted cut, or flatten out your fastball. Master the spin, and even average velocity can play up. 💨 Dial in your release. Trust the spin. Let your fastball work for you. 💪 #PitchingTips #FastballSpin #SpinEfficiency #BaseballTraining #PitchingMechanics #MLB #BaseballLife #ThrowGas
