Jack Sock tops 2014 champ Marin Cilic to reach U.S. Open’s 4th Rd
American Jack Sock eliminated 2014 U.S. Open champion Marin Cilic to reach the fourth round at Flushing Meadows for the first time.
The 26th-seeded Sock won 6-4, 6-3, 6-3 on Friday, taking all 14 of his service games and never facing so much as one break point. And he handled the Croatian’s big serve just fine, breaking the No. 7-seeded Cilic on four occasions.
The 23-year-old Sock’s only previous trip to the second week of a Grand Slam tournament came when he got to the fourth round of the 2015 French Open.
Sock is now 2-0 against Cilic, having come back from two sets down to win their Davis Cup match this year.
