Juan Martin del Potro cried for emotion after his quarter-final win over the Croatian Marin Cilic at the French Open. Following instead his loss to the Spaniard Rafael Nadal, the Argentinian said: ' I had a lot of break points. I couldn't make it. Rafa served well, played good points in that break points, and I got unlucky in that moment. Could be different match if I win the first set. But then he made me run a lot. Intensity is too high the whole match, and I couldn't stay thereafter the first set. He deserved to win.'
