Cordoba, February 9: Guido Pella upstaged third seed Diego Schwartzman in straight sets en route to the semifinals at the weather-affected Cordoba Open.
Pella – the eighth seed – claimed a 7-5, 6-2 win in the all-Argentinian affair on the clay courts of the ATP 250 tournament in Cordoba on Friday.
Seeking his maiden ATP Tour title, Pella has not dropped a set throughout the event ahead of a final-four showdown with either Aljaz Bedene or Pablo Cuevas.
"Since I arrived from Australia I felt good," Pella said. "This is my favourite surface and it was time to try to play better and get back to my best form and I am achieving it this week."
Bedene was leading Cuevas 3-1 in the first set when play was suspended due to rain and wind – the pair will resume their clash on Saturday.
Meanwhile, Federico Delbonis and Juan Ignacio Londero prevailed before the weather hit in Argentina.
Delbonis – who saved all break points he faced – defeated qualifier Jaume Munar 7-5 6-4 and Londero saw off Pedro Cachin 6-4 7-6 (7-3).
