He reached his career-high singles ranking of World No.
317 in June 2009 and his career-high doubles ranking of World No.

In February 2009, Eaton played what was then, the longest tennis match in history, lasting 6 hrs 40 mins, eventually beating James Ward.
This was a play-off match to decide the Davis Cup team, but it was not sanctioned by the ATP so was not an official record, and it was broken later.
