Michael is the caddy for 20-year-old phenom golfer Jordan Spieth, who recently made a huge statement on golfâs biggest stage, tying for second place at the 2014 Masters in Augusta, Georgia, with a 5-under par performance for the tournament. Everything was working in the major for Spieth â and for Michael as well.
Jordan Spiethâs golf caddie earned more than Tiger Woods this year. Jordan Spieth, who was named the PGA Tour's player of the year, took home a cool $22 million in prize money in 2015. But Spieth, 22, wasn't the only person to have reason to celebrate as a result of his lucrative season. His caddie Michael Greller should, too.
