BARCELONA, April 20 ― World number seven Stefanos Tsitsipas saved two match points to defeat Facundo Diaz Acosta and reach the semi-finals of the Barcelona clay-court tournament today.

The Greek came through 4-6, 6-3, 7-6 (10/8) after his 53rd-ranked Argentine opponent missed a match point in the 12th game of the deciding set.

Both men then saved more match points in the tie-breaker before Tsitsipas, a three-time runner-up at the Barcelona tournament, secured a ninth successive win following on from his Monte Carlo Masters title victory at the weekend.
