Jeff Knox is an Augusta National member who has been called on since 2003 to play with the last-place player when there is an odd number of golfers in the Masters Tournament field after 36 holes.
His job is to keep score for the Masters participant, who is either last or tied for last place after 36 holes, and provide company for him.
This year, Knox is playing in the first group with Jason Day.
There is mystery surrounding Knox when he serves as a marker because only the most devout Masters fans – and Augusta residents – know who he is. His name is not listed on the pairing sheet, which simply says “marker.” His name is not on the back of his caddie’s jumpsuit, and his score is not on the leaderboards.
Knox is chosen by the club to play with the pros because he is the club’s best player. He holds the members’ scoring record with 61, shot in a non-tournament round in 2003.
Knox became well known in golf circles after shooting 70 in the third round of the 2014 Masters, beating Rory McIlroy by a shot. The next day, he beat 1987 Masters champion Larry Mize.
