(February 2011). In the sport of golf, a gap wedge, also known as an approach wedge, is a wedge used to hit a shot with higher and shorter trajectory than a pitching wedge and lower and longer trajectory than a sand wedge. The name derives from the club's design to fill the gap between sand and pitching wedges.
An A wedge is usually a type of gap wedge, and it tends to fall in between the pitching club and the sand wedge. That means it could fall anywhere between 45 and 55 degrees. I have to add that I don't really use terms like sand wedge, lob wedge, gap wedge, or approach wedge anymore. I custom built my wedge set.
