Everyone knows that Andy Roddick's serve was a huge part of his success, helping him win the 2003 US Open and reach the No. 1 ranking. But some may have forgotten the time back in 2010 when he challenged his own serve, which was called in, against Gael Monfils in Tokyo.

Monfils would win the match 7-6 in the third, in what would become their last match against each other.

Mardy Fish had his two cents to add to this unusual throwback.

Roddick would retire two years later in 2012. He was inducted into the Hall of Fame this year.
