Swiss star Roger Federer has annexed his 18th Grand Slam trophy. In the summit clash of the Men's Singles at the Australian Open in Melbourne on Sunday, he defeated arch-rival Rafael Nadal of Spain in five sets 6-4, 3-6, 6-1, 3-6, 6-3. It was Federer's first Major title win after the 2012 Wimbledon. In the process, 35-year old Federer also became the second-oldest winner of a Grand Slam tournament in the Open Era after Australian Ken Rosewall won the Australian title at the age of 37 in 1972. Earlier in the Mixed Doubles final, India's Sania Mirza and her Croatian partner Ivan Dodig ended as runners-up, after losing to the Amerian-Colombian duo of Abigail Spears and Juan Sebastian Cabal in straight sets 2-6, 4-6. It is second runners-up finish for Sania and Dodig together, after losing the final of the 2016 French Open to Leander Paes and Martina Hingis.
