From 2002 to 2021 Knox served as the non-competitive marker for the Masters golf tournament.

Notable Matches at the Masters
In 2014, Knox was paired with then world number nine Rory McIlroy in the third round. Despite McIlroy finishing birdie-par-birdie-birdie and Knox bogeying the 18th hole, Knox defeated McIlroy 71 to 70. He followed that up in the fourth round by beating 1987 Masters champion Larry Mize 77 to 79. McIlroy would later say that Knox was "...the best [he'd] ever seen on Augusta's greens."

In 2006, Knox was paired with Sergio Garcia. To make the round more interesting, the two golfers are reputed to have placed a bet on the outcome of the round. After his tee shot went into the trees on the 18th hole, Garcia finished one over 73. Knox finished 72. Garcia refused to shake Knox's hand after the round. After the 2006 tournament, Jim Furyk said that Knox could "beat half the field who made the cut."

In 2008, Knox was paired with Miguel Angel Jimenez. On the first hole Jimenez drove a long tee shot straight down the fairway. Knox promptly outdrove him. Following this, Jimenez is reputed to have turned to Knox and told him not to outdrive him again. Knox did so again on the 10th hole.

In 2018 he made the only Saturday birdie on the 11th hole.

Knox has played rounds at the Masters with Keegan Bradley, Bubba Watson, Craig Stadler, Kelly Kraft, Jason Day, Ernie Els, Eddie Pepperell and Sung Kang among others.

Several notable golfers, including Phil Mickelson and Tiger Woods, have sought out Knox for his expertise before playing at Augusta.
