Diego Schwartzman has shrugged off a surprise defeat in his opening match to ease Argentina into the Davis Cup qualifiers on Sunday, sealing the winning point against Belarus.

The world No.15 was stunned by junior player Daniil Ostapenkov in Saturday' opening match but rebounded on Sunday to beat Alexander Zgirovsky 6-1 6-2.

Argentina had forged 2-1 ahead by winning Sunday's doubles rubber.

The South Americans will now go forward to the qualifiers in February hoping to seal their place in next year's Finals, having appeared in the inaugural edition in 2019.

"I don't know if it was revenge, because it didn't erase what happened to me on Saturday," Schwartzman said.

"But I enjoyed winning the final point."

The Netherlands also made it through to next year's qualifiers as they won their World Group I tie against Uruguay.

Wesley Koolhof and Matwe Middelkoop sealed their passage with a doubles win against Ignacio Carou and Martin Cuevas, giving the Dutch an unassailable 3-0 lead.

Brazil are also through to the qualifiers after seeing off Lebanon.

This year's Davis Cup Finals will take place in Madrid, Turin and Innsbruck in November with the two finalists automatically qualifying for the 2022 Finals.

The other 16 teams will enter the qualifiers along with the teams progressing from World Group I.
