A success that gives the semifinal against Opelka. "He is a difficult opponent - explains the Majorcan -. He has a fantastic serve, I will have to be concentrated in response and play aggressively from the baseline." The number 3 in the world then also returns to the fall in the first set that scared everyone in the stands: "I have some injuries. It was an unexpected fall, in a normal run, because here the lines sometimes rise and the foot is it's stuck.
