2018 US Open – Men's Singles


defeated Juan Martín del Potro in the final, 6–3, 7–6, 6–3 to win the Men's Singles tennis title at the 2018 US Open.
Rafael Nadal was the defending champion, but retired in his semifinal match against del Potro. Nadal and Roger Federer were in contention for the ATP no. 1 singles ranking at the start of the tournament. Nadal retained the number 1 ranking after Federer lost in the fourth round.
This tournament marked former World No. 3 David Ferrer's last participation in a Grand Slam tournament; he retired from his first round match against Nadal due to injury. This was also the last US Open appearance for former World No. 8 Marcos Baghdatis and the last Grand Slam tournament for Julien Benneteau, Gilles Müller, Florian Mayer, Carlos Berlocq and former World No. 8 and two-time US Open semifinalist Mikhail Youzhny. This was also the first Grand Slam tournament since Wimbledon 2017 in which former World No. 1 Andy Murray participated where he was granted a protected ranking at the start of the tournament. He lost in the second round to Fernando Verdasco.
Peter Polansky became the first player in history to qualify as a lucky loser for the main draw of all four Grand Slams in the same calendar year.
