Americans Sock, Ram advance to quarters on Newport's grass

NEWPORT, R.I. (AP) Americans Jack Sock and Rajeev Ram advanced to the quarterfinals of the Hall of Fame Tennis Championships on Wednesday.

Fourth-seeded Sock rallied past Lukas Lacko of Slovakia 3-6, 7-6 (4), 6-4. Ram defeated Yuichi Sugita of Japan 6-4, 6-3, a day after upsetting top-seeded John Isner.

The 31-year-old Ram returned the various slices, lobs and other change-of-pace shots offered by Sugita. The 161st-ranked Ram last won the Newport title in 2009.

The 22-year-old Sock, ranked 39th, needed two hours to advance in humid conditions on center court.
