Argentina reached the Davis Cup Finals group stage by eliminating Kazakhstan 3-2 in the best-of-five-match qualifying round when Sebastian Baez erased two match points and came back to edge Dmitry Popko 6-4, 3-6, 7-6 (6) on Sunday. Belgium, Chile, the Czech Republic and France also wrapped up victories Sunday. Baez is a 23-year-old who is currently ranked a career-high No. 25. He reached the third round of the Australian Open last month before losing to eventual champion Jannik Sinner. Popko, 27, is ranked No. 338 and has failed in 16 attempts to qualify for a Grand Slam tournament. Popko was in position to get Kazakhstan past 2016 Davis Cup champion Argentina, just one point away from winning while ahead 6-4 in the concluding tiebreaker. But from there, Baez grabbed the match’s last four points. Belgium clinched its spot in the next round with a 3-1 victory over Croatia that was sealed when Zizou Bergs beat Duje Ajdukovic 6-1, 7-5 on Sunday. Bergs also won the opening singles match Saturday against 2014 U.S. Open champion Marin Cilic. In Santiago, Chile, the hosts barely got past Peru 3-2 when Alejandro Tabilo came back to beat Ignacio Buse 2-6, 6-3, 6-2 in the deciding match.
