Available from Callaway is the Mack Daddy PM-Grind, which was the brainchild of a collaboration between Phil Mickelson and Roger Cleveland, Callaway’s chief wedge designer.

The PM-Grind is offered in lofts of 56, 58, 60, and 64 degrees and is a wizard around the green.
Its design and unique shape allows the face to be opened easily for bunker and lob shots, while grooves across the face and a higher CG make it more effective on shots played from deep rough. Like the MD3, the PM-Grind is also available in Satin Chrome and Matte Black finishes.
“We got a lot of feedback from tour players about how much spin they want to have with their gap wedges versus their sand wedge versus their lob wedge.” – Dave Neville – Callaway Global Director for Woods and Wedges
“I could control the ball even on shorter shots. It just felt a little heavier, which I like.” – Bob, TGW Customer 3 hdcp.
