Even without World No.5 Andy Roddick, the Americans remained heavy favourites going into the tie against Croatia.
The United States, attempting to recover from their first 0-2 deficit since 1934, were abolished by Marin Cilic as he beat James Blake 6-3, 6-3, 4-6, 6-2 to secure the quarter-final tie for Croatia.
The World No.15, who came into the match having never beaten his opponent Blake, came out firing to secure a 3-1 lead for the host nation.
Cilic created an impressive 23 break point chances for which he was able to capitalise on seven of them in the two hour and 42 minute match. The talented Croat struck 51 winners and just eight unforced errors as he dealt with the disappointment of the third set to hit back and seal the win in four sets.
