Jeff Knox is a legend at Augusta National.
Though the 52-year-old has never been a competitor in the Masters, he's racked up his share of tee times during tournament week, playing as a non-competing marker.
Essentially, when the field has an odd-number of contestants after the 36-hole cut -- like it did this year with 53 players advancing to the weekend -- Knox fills in with the odd man as a playing partner for pace of play consideration. This year's Saturday partner will be world No. 13 Paul Casey.

And don't expect Knox to be intimidated. In 2014, for instance, Knox was paired with Rory McIlroy in the third round... and beat him. That year, McIlroy finished T8 at the Masters and then won both the Open Championship and the PGA Championship.
So what kind of player is Knox? A pretty darned good one.
Knox has played in a number of USGA events through the years and once shot a 61 at Augusta National, a course record.
Players competing in the Masters often seek Knox out in the weeks leading up to the tournament for a practice round and to glean some of his knowledge of the tricky greens.
It's been reported, took care of business against McIlroy in some practice rounds leading up to this year's Masters.
So who has it better than Knox? He gets to play among the game's greats at his home course during one of the four biggest golf events of the year.
