Croatia clinches Davis Cup win over Ecuador

Croatia has clinched a spot in the Davis Cup quarterfinals after

Marin Cilic and Ivo Karlovic earned a straight-set win in doubles

to give the hosts an insurmountable 3-0 lead over Ecuador.

The Croatian duo defeated brothers Nicolas and Giovanni Lapentti

7-6 (3), 6-3, 7-5 after sweeping the opening singles on Friday.

Croatia, the 2005 Davis Cup champion, will face either Serbia or

the United States in the next round. The U.S. won the doubles match

Saturday to cut the Serbia lead to 2-1.

Cilic and Karlovic replaced original doubles pair Ivan Dodig and

Antonio Veic for the doubles.
