Laslo Djere stunned defending champion Juan Ignacio Londero to book his spot in the Cordoba Open semi-finals, while top seed Diego Schwartzman also advanced.

Djere dethroned eighth seed Londero following a 6-7 (5-7) 6-3 7-6 (7-5) victory on the Cordoba clay courts on Friday.

Serbian fourth seed Djere rallied from a set down to earn a semi-final showdown with Schwartzman at the ATP 250 tournament.

World number 14 Schwartzman defeated Spanish fifth seed Albert Ramos-Vinolas 6-0 7-6 (7-0) in one hour, 40 minutes.

Schwartzman, who lost to eventual champion Novak Djokovic in the Australian Open fourth round last month, is eyeing his fourth Tour title and first in his native Argentina.

Cristian Garin – the third seed – and Andrej Martin will meet in the other semi-final.

Garin prevailed 1-6 6-3 6-4 over sixth seed Pablo Cuevas and Martin accounted for Corentin Moutet 6-3 6-2.
