Reaction from nine-time ATP Rome Masters champion Rafael Nadal after he battled past resilient sixth seed Alexander Zverev in straight sets, 6-3, 6-4, on Friday to set up a semi-final meeting with the United States' Reilly Opelka. Nadal suffered a fall during the first set and saved all eight break points which he faced in the second, and the Spaniard's victory brought to an end a run of three consecutive losses against Zverev.
