Key Biscayne, Florida: Even with his surgically repaired back still nowhere near perfect, defending champion Andy Murray needed only 73 minutes to beat Jo-Wilfried Tsonga 6-4, 6-1 at the Sony Open Miami Masters on Tuesday and set up a quarterfinal with Novak Djokovic.
"My game is getting there," said Murray, the No. 6 seed, who acknowledged he was dealing with a sore back. "The last six sets I've played, very high-level tennis, very few errors."
He'll need to keep it that way against Djokovic, who eased past Tommy Robredo 6-3, 7-5.
The second-seeded Djokovic even gave back a point in the second set. A groundstroke from Robredo clipped the baseline and Djokovic couldn't handle it, but the ball was erroneously called out. After a review showed the ball was in, the point was ordered to be replayed.
