Playing in just his second claycourt match of the season, Juan Martin del Potro scored a first-round win over Grigor Dimitrov at the ATP Rome Masters.
The victory improved his head-to-head record over the Bulgarian to a perfect 5-0.
“I think I played well during the whole match. I had my break points in the first set, and Grigor played better in that moment. I think he took the opportunities,” del Potro told atpworldtour.com.
“But in the second and in the third I played solid from the baseline. I hit harder with my backhands, and I think my serves helped to win the match.”
Also advancing in Rome on Monday were Tomas Berdych, David Goffin and Sam Querrey, who upset 11th seed Lucas Pouille.
