So much for the United States getting two men into the fourth round of the French Open for the first time in 15 years.
No. 23-seeded Jack Sock bowed out Friday, beaten 6-7 (2), 6-4, 6-4, 4-6, 6-4 by 55th-ranked Albert Ramos-Vinolas of Spain in a match that lasted 4 hours, 11 minutes.
Sock, a graduate of Blue Valley North High school, was hurt by 76 unforced errors, 11 more than his winners total.
The other American man who made it to the third round, No. 15 John Isner, faces on Teymuraz Gabashvili of Russia on Friday.
The last time two U.S. men reached the fourth round in Paris was in 2001, when Andre Agassi and Michael Russell did it.
Sock and doubles partner Vasek Pospisil were still in the event after winning their first-round match on Thursday.
