(Reuters) - Spain’s Jaume Munar battled back from a set down to defeat second-seeded Italian Fabio Fognini 4-6 6-4 7-5 in the Argentina Open on Wednesday and advance to the quarter-finals.
The unseeded 21-year-old, who qualified for last month’s Australian Open but retired against Fognini in his first match, followed up his run to last year’s ATP Next Gen semi-finals by beating the world number 15 at the second time of asking.
“It’s the best victory of my career,” said Munar, who is ranked 77th in the world.
Fognini had Munar on the ropes in the final set and got to within two points of victory, but the youngster rallied, breaking the 31-year-old to level at 5-5 and winning with a burst of 12 points in a row.
He will battle local hope Guido Pella for a place in the semi-finals.
