Taylormade Design Group created this putter to commemorate Jason Day's WGC win in 2014. The putter has his exact specifications which were once found on the Taylormade vault website until the page disappeared. I purchased this directly from Taylormade and I've been the only owner. I've brought this to the course less than 5 times and it only has some wear on the grip and one small mark on the head.
