NEW YORK (Reuters) - Twice champion Rafa Nadal was out practising early shortly before the first balls were hit at the U.S. Open on Monday as the tournament gets off to an exciting start with Maria Sharapova taking on world number two Simona Halep.
Russian Sharapova, who this season returned from a doping ban, was granted a wildcard entry to the last grand slam of the season but received a tough first-round draw in the shape of Romanian Halep.
