Schwartzman beats Nadal in Rome Diego Schwartzman upset Rafael Nadal 6-2 7-5 at the Italian Open quarter-finals. The Argentine will next face Denis Shapovalov, who defeated defeated Grigor Dimitrov 6-2 3-6 6-2. Rafa struggled with his serve throughout the match and made a series of uncharacteristic unforced errors that proved to be his undoing. The Italian Open was the Spaniard's first tournament in over seven months and while he cruised through the previous two rounds, his rustiness showed from the outset against the 15th-ranked Schwartzman. Nadal committed 30 unforced errors to Schwartzman's 17 and had his serve broken five times. "Losing that many serves, you can't expect to win a match," Nadal said. "So that's something that I have to fix. I know how to do it." Nadal will now travel to Paris, where he will look to clinch a record-extending 13th French Open title.
