For the second year in a row, the Swiss beat the German pairing of Alexander Zverev and Angelique Kerber by claiming a deciding mixed doubles rubber which was loaded with drama. It was Switzerland's fourth title overall, behind only the United States with six, and Federer first won the Hopman Cup back in 2001 when he teamed with Martina Hingis.
The 37-year-old gave the Swiss the early ascendancy with a straight sets win against Zverev, before Kerber squared the tie by beating a dogged Bencic to set up the mixed doubles decider. Federer was a dominant figure in an extraordinary doubles match as the Swiss claimed the abbreviated format 4-0, 1-4, 4-3 (5/4) to clinch the title despite Germany having two match points.
