About this ball

Stay Aggressive Longer! Hammer Spawn was built to do what strong bowling balls often can’t — let you stay aggressive as the lanes transition. Designed as a true high-performance asymmetrical benchmark, Spawn reads the midlane with confidence while maintaining the continuation Hammer is known for. Using the proven Zero Mercy coverstock paired with more stable core dynamics, Spawn creates traction in the oil without the early roll, and going forward, that often happens when players move in. The result is a ball that allows bowlers to open their angles and retain energy and continuation through the pins. Positioned perfectly between the Black Widow 3.0 Dynasty and the Zero Mercy Solid, Spawn adds to the Hammer lineup by combining traction with powerful continuation. It’s the strong ball you can stay in longer, delivering ball motion and scores expected when you buy a Hammer.
