Rafael Nadal has been dominating the clay season. Until a straight-set loss to Dominic Thiem in the quarterfinals of Madrid, he had won 50 straight sets (a record) on clay, dating back to his last loss to Thiem in Rome last year.
Of course, there's still Rome to go in terms of warm-up events, but anything can happen once the tour arrives in Paris for Roland Garros. Looking ahead, who—from this list of options—do you think can stop the Spaniard from claiming his 11th title in Paris?
