The USA and Serbia are tied 1-1 after splitting Friday’s Davis Cup quarter-final singles rubbers in Boise.
World No. 1 Novak Djokovic won the first point for the Serbs, defeating John Isner 7-6(5), 6-2, 7-5 in two hours on Friday. Djokovic capitalised on all four of his break points and withstood 17 aces to notch his third win in four meetings with Isner.
“To start with a win is a huge advantage. We’ve been practising the past six or seven days in these conditions, as this is the highest altitude we’ve ever played in and it plays an important role,” said Djokovic. “I played a very good match. I stayed composed and patient, waiting for my chances. I returned well when I needed to and served consistently at a high level.”
The 25-year-old Djokovic has a 21-7 singles record in Davis Cup play. He led his country to its first title in 2010. Serbia’s run to the crown that year included a first-round win versus the Americans in Belgrade, which saw Djokovic clinch the tie with a five-set win over Isner in a reverse singles rubber.
Sam Querrey battled past Viktor Troicki 7-6(1), 3-6, 4-6, 6-1, 6-4 to draw host USA level. The top-ranked American broke Troicki for the fifth time at 5-4 in the fifth set and served out the comeback victory in three hours and 20 minutes. Querrey improved to 3-0 in Davis Cup action this year.
