PORTLAND, Ore. — Borna Coric beat Jack Sock 6-4, 3-6, 6-3, 6-4 to give Croatia a 3-2 comeback victory over the United States on Sunday in their Davis Cup quarterfinal match.
Marin Cilic set up the deciding fifth match by beating John Isner 7-6 (11-9), 6-3, 6-4 in the first reverse singles match on the Tualatin Hills hard courts.
After the United States swept the singles matches Friday, Cilic and Ivan Dodig kept Croatia alive Saturday with a four-set victory over twins Bob and Mike Bryan in doubles.
Croatia will host France in the World Group semifinals on Sept. 16-18. Croatia reached the semifinals for the first time since 2009. It won its only Davis Cup title in 2005.
The U.S. lost for the fourth time in 161 tries when leading 2-0 lead in a Davis Cup tie.
The 19-year-old Coric was on the way to winning when he broke Sock’s serve in the ninth game of the fourth set.
Cilic, playing his third match in three days, overcame a hot-serving Isner in the first set to win in a tiebreaker. Isner won 31 of his 35 service points, but dropped three during the tiebreaker as Cilic won 11-9.
Cilic finally broke Isner’s serve during the eighth game of the second set, leading to a 6-3 win and a two-set lead.
Unlike Friday’s first singles match, when Cilic lost after leading Sock by two sets, the world’s No. 12-ranked player finished off Isner by breaking him in the ninth game to pull out a 6-4 win.
Cilic is 6-0 against Isner.
