Jason Day already broke through the Major ranks by winning the 2015 PGA Championship, and has contended in every other Masters as well, including two Top 5s in the Masters Tournament. He seems poised to win in Augusta eventually, as he's never finished worse than T28 in the 7 Masters Tournaments that he finished (he had to WD once).
Offered here is a Titleist Masters Tournament logo golf ball that is beautifully autographed by Jason Day.
