Jason Kubler, Alex de Minaur lift Australia past Belgium in Davis Cup opener

Davis Cup finals group phase on Tuesday with Jason Kubler and Alex de Minaur paving the way for a 3-0 win over Belgium. Newcomer Jason Kubler battled past 134th-ranked Zizou Bergs 6-4, 1-6, 6-3 in the opening Group C tie in Hamburg, Germany. Trailing 1-3 in the third set after dropping the second, 97th-ranked Kubler reeled of five consecutive games to earn the first point for Australia.

"I'm over the moon that I was able to deliver today but we may not have been in this position if it were not for Jason Kubler who came out on his debut and pulled a rabbit out of the hat," said de Minaur. "He played with passion and pride and showed everything that Davis Cup is about. He got the win which gave us a 1-0 lead which I thought was huge." De Minaur got the winning point for the 28-time Davis Cup champions after beating David Goffin 6-2, 6-2 in one hour and six minutes.

Goffin, ranked 62, a Davis Cup finalist in 2015 and 2017, has never beaten 22nd-ranked Minaur in their four meetings. Matthew Ebden and Max Purcell teamed up in the doubles to see off Sander Gille and Joran Vliegen 6-1, 6-3. The Germans open their Group C campaign against France on Wednesday before also facing Belgium and Australia.

In Group A, Argentina play Sweden on Tuesday with Canada and South Korea in action in Group B and Kazakhstan v Netherlands in Group D. In the last-16 group phase, nations play two singles matches and then a doubles in a best of three format. The top two teams in the Davis Cup group matches progress to the last eight in Malaga from November 22-27.
