Hammer Black Widow Spare Plus Bowling Ball

The Hammer Black Widow Spare+ gives you the predictable, straight reaction you want from a spare ball with unmistakable Black Widow DNA.

Wrapped in a durable Polyester coverstock, the Black Widow Spare+ is designed to minimize hook and travel straight through the lane, making it a dependable choice for corner pins and other spare combinations where accuracy matters most. The polished finish helps it clear the lane cleanly without trying to grab when you don't want it to.

What really separates the Spare+ from your typical plastic spare ball is what's inside. Hammer pairs the polyester shell with the legendary Gas Mask Core, bringing one of the most recognizable core designs in bowling to a ball built specifically for spare shooting. You get the straight, predictable reaction you need with a little more Hammer personality under the hood.

Finished in White Diamond, it has a clean, premium look that stands out in your bag and on the lane. If you're a Hammer or Black Widow fan looking for a dedicated spare ball to complete your arsenal, the Black Widow Spare+ is an easy choice.
