In the second set, Goffin broke to lead 2-1. At 5-4, he could serve to win the match, but conceded a break to Bonzi. The French also won the next two games (5-7) and came back to one set everywhere.
Goffin was not demoralized and took the service of his opponent from the first game of the decisive set. He managed another break to lead 4-1. Bonzi came back to 4-2 in stride then to 4-3. But Goffin did not tremble, winning the next two games and winning 6-3 on his second match point.
In the first match of the day, Michael Geerts (ATP 268) was beaten 6-3, 6-3 by Richard Gasquet (ATP 79).
The last duel will pit Belgian doubles Sander Gillé (ATP 78 doubles) and Joran Vliegen (ATP 90 doubles) against the pair formed by Nicolas Mahut (ATP 27 doubles) and Arthur Rinderknech (ATP 144 doubles).
After their 3-0 defeats against Australia and 2-1 against Germany, Belgium are already eliminated. France, beaten 2-1 by both Germany and Australia, also has nothing to hope for. Germans and Australians will face off on Sunday for first place in the group.
The top two from each of the four groups advance to the knockout stage, held November 22-27 in Malaga.
