Mardy Fish will feature in an episode of the new Netflix series, “Untold: Volume One,” a five-episode docuseries exploring several of the most compelling stories in sports.

The former world No. 7 and 2004 Olympic silver medalist shared the trailer, which alluded to his struggles with arrhythmia and anxiety, on his official Twitter account on Tuesday.

A three-time Grand Slam quarterfinalist, Fish enjoyed a career-best season in 2011 when he reached three Masters 1000 semifinals and finished runner-up to Andy Murray at the Rogers Cup in Canada.


The following year he began suffering from severe bouts of cardiac arrhythmia, which would trigger a protracted battle with anxiety. Fish would write about an episode that forced him to withdraw from an anticipated match with Roger Federer at the 2012 US Open for The Players’ Tribune.

“We were in the car…and my thoughts were filling with dread,” he wrote. “Would it happen on the court again? Was I going to get an anxiety attack, again, in front of thousands of people? Was I going to get an anxiety attack while trying to do my job?

“The thoughts kept coming, and they wouldn’t stop. They just kept coming, and coming, and coming. I was in a very bad place.”

Fish ultimately retired in 2015 after going public about his chronic anxiety, and later became captain of the U.S. Davis Cup team.
