Hvem vinder den australske åben mænds single titel i 2018?
Roger Federer
2018 Australian Open – Men's Singles
Roger Federer var den forsvarende mester og forsvarede sin titel med succes ved at besejre Marin Čilić i finalen med 6-2, 6-7(5-7), 6-3, 3-6, 6-1. Det var Federers 20. Grand Slam-titel i single og hans rekordstore sjette Australian Open-titel i herresingle (sammen med Roy Emerson og Novak Djokovic).
Med sejren blev Federer den første mandlige spiller til at vinde mindst seks titler ved to Grand Slam-turneringer (seks ved Australian Open og otte ved Wimbledon). Federer blev den ældste mand til at vinde en Grand Slam-titel i single i Open-æraen siden Ken Rosewall i 1972. Tiden mellem Federers første Grand Slam-titel i Wimbledon og denne seneste, næsten 15 år, er en rekord i Open-æraen inden for herresingle.
Det var også 10. gang, at Federer forsvarede en Grand Slam-titel, og den sidste gang var ved US Open i 2008. Čilić blev den første kroatiske spiller til at nå en singlefinale i Australian Open.

2018 Australian Open – Men's Singles
Roger Federer was the defending champion and successfully defended his title, defeating Marin Čilić in the final, 6–2, 6–7(5–7), 6–3, 3–6, 6–1. It was Federer's 20th Grand Slam singles title and record-equalling sixth Australian Open men's singles title (tied with Roy Emerson and Novak Djokovic).	
With the win, Federer became the first male player to win at least six titles at two Grand Slam tournaments (six at the Australian Open and eight at Wimbledon). Federer became the oldest man to win a Grand Slam singles title in the Open era since Ken Rosewall in 1972. The time span between Federer's first Grand slam glory at Wimbledon and this latest, almost 15 years, is an Open era record in the men's singles field.	
This was also the 10th time that Federer has defended a Grand Slam title, with the previous time being at the 2008 US Open. Čilić became the first Croatian player to reach a singles final at the Australian Open.
