Nadal rallies to defeat Mayer, advances to 4th round

NEW YORK - No. 1 seed Rafael Nadal rallied after dropping the first set again, moving into the fourth round with a 6-7 (3), 6-3, 6-1, 6-4 victory over Leonardo Mayer with the roof at Arthur Ashe Stadium closed because of rain.

Just as in his win over Taro Daniel on Thursday, Nadal started slowly before finding the range on his punishing shots and dominated the next three sets.

The two-time U.S. Open champion advanced to the round of 16 for the ninth time and will play unseeded Alexandr Dolgopolov of the Ukraine.

Mayer fell to 1-25 against Top 10 opponents.
