Rosario: 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, the Czech Republic and France also wrapped up victories Sunday, while Chile and Peru were in action at night.
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.
