Greek 19-year-old Stefanos Tsitsipas stuns Dominic Thiem in Barcelona
Greek teenager Stefanos Tsitsipas stunned clay-court specialist Dominic Thiem on a day of surprises at ATP Barcelona.
The world number 63’s breakout week continued with a 6-3 6-2 dismantling of the Austrian third seed, supposedly an outsider for glory at next month’s French Open.
Tsitsipas, 19, had already beaten seeded Albert Ramos and Diego Schwartzman.
Elsewhere, second seed Grigor Dimitrov fell to Spain’s Pablo Carreno Busta 6-3 7-6(4).
World number one Rafael Nadal extended his winning run on clay to an incredible 42 consecutive sets as he beat Martin Klizan 6-0, 7-5.
Nadal looked like he would breeze past Novak Djokovic's conquerer when he bageled the first set.
But world number 140 Klizan made him sweat, getting three set points to potentially take it to a decider.
However Nadal dug deep and battled back to take the second game and charge into the semi-final.
He will face David Goffin in the semi-finals after he beat Roberto Bautista-Agut 6-7, 6-2, 6-2.
