A dramatic quarterfinal day saw tournament favorite Alexander Zverev exit ATP Buenos Aires. His conqueror, Francisco Cerundolo, is keeping home hopes alive and will play a semifinal at the Argentina Open for only the second time in his career. Elsewhere, Joao Fonseca, who saved two match points against Mariano Navone, will meet Serbian qualifier Laslo Djere. Who will reach the title match?<\/p>\n
Head-to-head:<\/strong> first meeting<\/p>\n Joao Fonseca survived in an epic match against Mariano Navone. The 18-year-old avenged his loss to Navone from Rio last season by saving two match points late in the third set. He prevailed 3-6 6-4 7-5 to become the youngest Brazilian semifinalist in the Open Era. This will be his first semifinal at the ATP level.<\/p>\n Laslo Djere, for his part, overpowered Thiago Seyboth Wild 7-6 6-3. It is now five wins from qualifying for the 29-year-old Serbian. But a sixth win is far from assured, even though clay is Djere’s domain. Fonseca’s relentless aggression and ability to conjure some otherworldly shots under pressure will be challenging to contain.<\/p>\n Prediction: Fonseca in 3<\/em><\/p>\n
