They make almost as much as a brain surgeon. Yes, you read that right. Professional golf players don't just need caddies to carry around their bags. They strategize for their games along with their caddies. For a dozen years, between 1999 to 2011, Steve Williams was a caddie to the legendary golf player Tiger Woods. He was by Tiger Woods' side for 13 out of his 15 major title wins. During their time together, the duo won 72 games worldwide. Steve Williams earned 15% of Tiger Woods' tournament rewards. This amount would sometimes be higher than the money professional tournament players made. He also earned well through endorsements. Reportedly, Steve Williams earned a minimum of $12 million in salary and bonuses. He was also given ten vehicles by Tiger Woods that the player had won during tournaments. In 2007, Steve Williams had earned $1.4 million, placing him on the list of the 75 top PGA earnings for the year. This truly blows the mind, as Williams had not played a single round of golf, yet he ended up making more money than some of the players. More recently, Joe LaCava, Tiger Woods' caddie on his tour in 2018, earned $5.4 million. This amount is very close to the median income for a brain surgeon.
