Thiem sets up Monfils semi-final showdown
Top seed Dominic Thiem will go head-to-head with entertaining Frenchman Gael Monfils in the semi-finals of the Argentina Open.
Thiem earned his second final-four appearance of the season after defeating home favourite Guido Pella in straight sets on Friday.
The Austrian world number six triumphed 7-6 (9-7) 6-4 at the ATP 250 event on clay courts in Buenos Aires.
Pella saved five set points prior to the opening-set tie-break before earning two of his own at 6-4.
However, Thiem was too strong as he set up a mouth-watering showdown with Monfils.
Monfils dug deep to see off Argentina's Leonardo Mayer 6-4 3-6 6-3 on Friday.
The 31-year-old, who lost in the second round of the Australian Open after struggling in sweltering conditions against Novak Djokovic, saved three of five break points to prevail in his quarter-final clash.
Meanwhile, fifth seed Diego Schwartzman was upstaged by Aljaz Bedene 6-4 6-4 and Federico Delbonis trumped Guillermo Garcia-Lopez 6-3 7-5.
