The MD stands for Mack Daddy, I thought it sounded silly when I tried these out, but I soon changed my mind. I have a low-ball flight and I found that Callaway mack daddy 5 wedges span the nuts off the golf ball. The production and improvements on the Callaway mack daddy 5 (MD) grooves continue with the JAWS MD 5 Raw wedges.
MD grooves are a feature on Callaway wedges that are designed to increase spin and lower the impact position on the ball. This will benefit players that strike the ball well off tight lies.
