Can't blame you for being surprised on that roll out! Definitely not normal. Almost as if it hit a sprinkler head, but there isn't one 2 yds onto the green. I think your shot was one of those anomalies that have been popping up recently.
After reading your post I played a practice 9 on BP and when I got to #18 I positioned the ball to hit a PW into that front pin position. (I had the original back pin position on the practice hole.) I hit a full Rapture Pro V2 PW (plays 10yds longer than your PW) and it landed about 2 yds on the green and rolled out 4 yards. I screen captured a replay shot.
Then I then whacked the ball off the green back down the hill into the fairway and positioned the ball in about the same spot. I then hit a full TM Master Z Satin 54 wedge and it also landed about 2yds on the green but it stuck, rolling out 0 yds. I screen captured a replay shot as well.
The ball I used is a Tour GI-S which has the same 2 dots of spin as your Tour-SD
I over-layed one of the screen shots on the other. Here's the result. Right click and View Image for a bigger picture.
TM 54 on the left and Rapture Pro PW on the right. I was a bit surprised at how much higher the trajectory of the TM 54 was. Both clubs are rated at 110yds and give quite different results on landing. In this case the PW shot would have been closer to the front pin. But neither shot had any unusual roll out.
