BUENOS AIRES, Argentina (AP) Dusan Lajovic beat Diego Schwartzman 6-1, 6-4 to help Serbia avoid a clean sweep to Argentina in the Davis Cup quarterfinals on Sunday.
Argentina wrapped up a spot in the semifinals by winning the doubles match on Saturday, and a day earlier it had won both singles matches in the clay-court tie at home.
In the second singles on Sunday, Serbia's Filip Krajinovic retired while trailing 6-1, 3-0 to Argentina's Carlos Berlocq.
Argentina is trying to win its first Davis Cup title. It has made it to the semifinals in eight of the last 10 years, but in 2014 it was knocked out in the first round.
Serbia, without top-ranked Novak Djokovic, was trying to reach the semis for the first time since 2013.
