Australia's John Peers and Jordan Thompson beat Ruben Bemelmans, 29, and Arthur De Greef to give Australia 2-1 lead over Belgium in the Davis Cup World Group semi-finals.
Doubles world No. 2 Peers and compatriot Thompson easily saw off Bemelmans and De Greef on the clay of Brussels 6-3 6-4 6-0.
After losing the first set -- the Bemelmans and De Greef held on until the fifth game -- when they got broken.
The Belgian duo won just two games in the rest of the match.
Peers and Thompson converted 5-of-9 of their break point tries and never got broken in just over an hour and a half of play.
Peers and Thompson, who debuted as a Davis Cup pair today, played together for the first time this past June in s'Hertogenbosch.
2017 Cincinnati Masters runner-up Nick Kyrgios will be hoping to close out the tie on Sunday.
Kyrgios, who is unbeaten in Davis Cup this year, is set to clash off against Belgium's ace David Goffin in the fourth rubber on Sunday.
2003 Davis Cup champion and now Australian team captain Lleyton Hewitt would love to see Kyrgios get the job done and escape the deciding rubber.
