The TaylorMade Z TP wedge features the new Z groove that promotes increased spin to help stop the ball more quickly. The Z groove is so-named because TaylorMade's R&D team uses the letters of the alphabet to name the grooves it develops. TP stands for Tour Preferred, and delineates those TaylorMade clubs that have been designed with the express input and feedback of tour professionals. The Z groove features 10% more volume than TaylorMade's Y grooves, also known as Y-cutter grooves. The Z groove's larger volume equals added room to channel groove-clogging, spin-killing obstacles such as grass, debris and moisture. Z grooves also incorporate strong, sharp edges designed to deliver added traction on the ball's cover to promote more shot-stopping bite. Like all TaylorMade wedges, the TaylorMade Z TP combines a classically beautiful teardrop shape with large rac Feel Pockets on the back side of the club head. The size, shape and position of the Feel Pockets help to channel impact vibration to strategic areas of the club head to promote the exceptionally soft-yet-solid feel at impact. The TaylorMade Z TP wedge also features a smoky-looking PVD finish.
