Fish's friend and fellow tennis player James Blake served as groomsman. He is also good friends with Andy Roddick and Bob and Mike Bryan. Fish went to Vero Beach High School with country music star Jake Owen and remains good friends. The two have repeatedly done charity events together in Vero Beach to raise money for their favorite charities. Fish is a fan of the Minnesota Vikings. Fish has a group of fans called "The Fishheads" who travel with him and cheer him on during matches:   The setting was center court at Arthur Ashe Stadium yesterday, and the crowd filled only half the seats as Mardy Fish took the court for the second match of the day. But as Fish methodically made his way through a straight-set victory, an odd, and somewhat comical, sight emerged in the otherwise sedate setting. Perched high in the cheap seats, relatively speaking, were a raucous band of shirtless fans, each one with a letter that collectively spelled out, "Go Fish." Their heads were adorned with rubber fish heads and there were fins attached to their hands that they slapped together enthusiastically for each point scored by Fish. Fish is regarded as one of the best celebrity golfers. He is annually among the favorites at the American Century Championship in Lake Tahoe. He won the Diamond Resorts Invitational in Orlando in both 2016 and 2018.
