Chris Eubanks caused a major upset at Wimbledon as he knocked out fifth seed Stefanos Tsitsipas in the fourth round to set up a quarter-final clash against former US Open winner Daniil Medvedev.
In fact, Eubanks had never got further than the second round at a Grand Slam tournament before this year's Wimbledon and had actually begun a commentary career with the Tennis Channel last year to help support himself.
At the time, Eubanks was ranked outside the top 150 and could not have dreamed of a Wimbledon run like the one he is on at the moment. Since starting to commentate, Eubanks has enjoyed a remarkable run of form with his performances.
