Roger Federer and Belinda Bencic of Switzerland won the Hopman Cup on Saturday.
The pair defeated Germany's Alexander Zverev and Angelique Kerber 4-3(3) 4-2 in the decisive match of the final.
Federer recovered from a set down to beat Zverev 6-7 6-0 6-2 in the opener, giving Switzerland the lead, but Germany drew level when Kerber beat Bencic 6-4 6-1.
Federer first lifted the Hopman Cup in 2001, partnered with Martina Hingis.
"It's amazing," Federer said. "My week with Martina Hingis at the time is a little like what it must be like for Belinda. I didn't know then what my career was going to be like."
Bencic added: "This is a dream come true for me and I couldn't wish for a better partner. I'll never forget this week, it's absolutely incredible.
"I so enjoyed being back. It's a great preparation for the Australian Open."
Federer is 15/8 to defend his Australian Open crown with Sky Bet, having been supported since Andy Murray confirmed his withdrawal from the event.
Bencic meanwhile is a 28/1 shot for the women's event, in which joint-favourites Garbine Muguruza and Karolina Pliskova are 7/1.
