HILTON HEAD ISLAND, S.C. -- Carrying a handful of wedges in his right hand, Roger Cleveland, Callaway's Chief Club Designer, made his way down the range at Harbour Town Golf Links on Monday afternoon, stopping for a couple minutes along the way to chat with players and caddies about his latest creation -- a Callaway prototype wedge called "Mack Daddy 2."

According to Cleveland, the wedge comes in two lofts (58 and 60 degrees) and three different grinds (S-grind, C-grind and U-grind). The "S-grind" (Standard grind) and U-grind have a bounce of 10 degrees, while the C-grind has a bounce of 14 degrees.
The wedge also features a textured face that has milling between the scorelines and, as Cleveland noted, grooves that are more aggressive but still conform to USGA groove regulations.
Colt Knost and defending RBC Heritage champion Carl Pettersson tested the prototype wedge on Monday and both requested 60-degree wedges with the U-grind.
While it's unclear if either player will put the wedge in play this week, the prototype is already in the bag of two former major winners. Cleveland confirmed Phil Mickelson started carrying a 60-degree U-grind several weeks ago, and Ernie Els used one last week at the Masters.
