Gauff: 'Something special about Nadal and Roland Garros'
Nadal has not played since suffering a hip injury at the Australian Open in January and there are doubts about the Spaniard's participation in Paris after the 22-time major champion pulled out of the Italian Open.
Gauff said Nadal would be her first pick to win in Paris if he is fit enough to play, despite his lack of time on court.
"I don't think he needs match experience," she told reporters in Rome."I'm sure he probably would have preferred to play some matches before. Him and Roland Garros is something special.
"I made the mistake of doubting him (last year)," the American added."Next thing you know, he pretty much stormed his way to the final and won in straight sets."
Gauff, who finished runner-up to Iga Swiatek at the French Open last year, continues her build-up to the May 28th-June 11th tournament when she faces Marie Bouzkova in Rome on Saturday.
