The verdict is in, and I'm taking Nick Watney with my one-and-done for the Shriners Hospitals for Children Open. It essentially came down to Watney and Graham DeLaet, and when I compared them head-to-head, Watney won out.
I went back to 2010, and in each of his three trips Watney gained strokes with the putter, while DeLaet lost with his in his only start. Both were outstanding with GIR.
Tough call, but I will likely go with DeLaet when ball-striking is a little more demanding and the winning score needs to be in the mid teens, and not deeper than 20.
Best of luck to all!
