In July 2013, he made it to his first final of the year at the Hall-of-Fame Championships, defeating Matthew Ebden, Prakash Amritraj, Jan Hernych, and John Isner on the way. He was beaten by Nicolas Mahut having served for the championship at 5–4 in the second set. His form continued at the 2013 BB&T Atlanta Open, defeating Édouard Roger-Vasselin 6–4, 6–4, Rhyne Williams 7–6, 6–4 and Ivan Dodig 1–6, 6–3, 6–0 in the quarterfinals. Hewitt played John Isner in the semifinals, but lost in three tough sets. His 2013 US Open (tennis) run started well, beating Brian Baker (tennis) in four sets and following up with a five-set epic upset against fellow former US Open champion Juan Martín del Potro, where Hewitt came back from two sets to one down against the No. 6, winning a fourth set tiebreak and sealing the match 6–1 in the fifth. He beat Evgeny Donskoy in the third round to set up a fourth round match with Mikhail Youzhny. Hewitt then lost to Youzhny 3–6, 6–3, 7–6, 4–6, 7–5, despite leading 4–1 in the fourth set and serving for the match at 5–3 in the fifth set. A measure of the success of Hewitts 2013 season is the fact that he won the John Newcombe as the most outstanding Australian tennis player in 2013, a year in which he returned to the worlds top 100.
