BOISE, Idaho (AP) - Even an ankle injury couldn't stop world No. 1 Novak Djokovic from dominating Sam Querrey 7-5, 6-7 (4), 6-1, 6-0 to give Serbia an insurmountable 3-1 lead in this Davis Cup quarterfinal at the Taco Bell Arena on Sunday.
At 1-1, 30-40 and a second breakpoint opportunity on Querrey's serve, the world No. 1 twisted his right ankle off a forehand and fell to the ground.
Wincing in pain, Djokovic had to be helped courtside. But after having the ankle taped and taking anti-inflammatories, he continued to play. He broke serve on his third breakpoint in that third game.
Serbia advances to the September semifinal against the winner of the quarterfinal between Canada and Italy being held in Vancouver this weekend.
