Callaway’s original PM Grind was a one-off prototype designed by Roger Cleveland with major input from Phil
Mickelson. The idea was to create a wedge to help Phil better hit the high, soft-landing flop shots for which he’s
famous. The club was characterized by a uniquely shaped head with an exceptionally high toe and expansive
face area, including grooves spanning the entire face, both from side-to-side and up-and-down. Phil loved the
prototype and put it straight into play, at the 2014 PGA Championship, and nearly won. That validation led Callaway
to introduce it to the public in 2015; it quickly gained an avid and loyal following among golfers who found it
exceptionally easy to use from greenside bunkers, in addition to helping with flop shots.
During the past three years Phil has worked with Roger on improvements to the PM Grind that make it easier to hit
three essential shots Phil thinks every golfer needs:
The result is the new PM Grind 2019, which has four key improvements: Offset Groove-in-Groove technology,
increased offset, a higher toe, and a new C-grind sole configuration.
