Second-seeded Italian Fabio Fognini was eliminated from the Argentina Open by Spain's Jaume Munar 4-6, 6-4, 7-5 in the second round of the Buenos Aires event on Wednesday.
Fognini, ranked 15th in the world, came within two points of victory with a 5-4 advantage in the final set. Munar was tenacious and snagged the biggest victory of his career.
"This is my best victory," Munar remarked while celebrating the victory. Hie will advance to the quarter-finals to face opponent Argentine Guido Pella.
Pella defeated compatriot Leonardo Mayer 6-4, 1-6 and 7-6 (7/5) in the second round, and is thirsty for more victory after losing the final of the Cordovan tournament last Sunday.
Pella will face Spain's Munar in the next round of the clay court tournament.
