I've got two pitching wedges and two techniques that I use. If I have 130 yards and want to hit a low shot, I'll hit my normal 46½-degree pitching wedge and try to arm it in there. The ball will come in lower and will roll forward.
I'll use that lower shot if the pin is in the back so I can bounce it in there. If the pin is in the front, I'll hit a three-quarter, 48-degree pitching wedge that will come in higher and spin back.
