Since turning pro in 1992, Phil Mickelson has racked up the accolades with over half a century of professional wins, including three Masters Green Jackets, a Claret Jug and a Wanamaker Trophy.
But who is 'Lefty’s' trusty right hand man on his bag?
Since 2017, Mickelson’s caddie has been his brother Tim Mickelson.
Mickelson made a big change in 2017, splitting with long-time caddie Jim ‘Bones’ Mackay, who had been on his bag since 1992 and for all of his major wins. When they went their separate ways, Phil opted to replace him with for a familiar face.
Despite teaming up with his brother later in his career, Tim Mickelson has still experienced success alongside Phil, claiming victory at the 2018 WGC-Mexico Championship and the 2019 Pebble Beach Pro-Am.
"He's a really good caddie," said Phil Mickelson. "He knows my game very well. He knows what I do - and what I should do."
Mickelson’s career is just as steeped in golf as his brother, coaching for eight years at the University of San Diego before moving on to coach Jon Rahm in his college years at Arizona State.
When Rahm turned professional in 2016, Tim worked for him as his agent at Lagardere Sports until his brother asked him to pick up his bag.
The 25-year partnership between Phil Mickelson and his former caddie, Mackay, is one of the most famous player and caddie partnerships in golf history, so much so veteran Mackay was inducted into the 'Caddie Hall of Fame' in 2017.
