Djokovic earned two more service breaks in the fourth set, including one to take a 4-1 lead when U.S. Open champion Murray double-faulted on break point.
“It's been an incredible match as we could have expected,” Djokovic said. “When we play each other, it's always, we push each other to the limit and I think those two sets went over two hours, 15 minutes, physically I was just trying to hang in there. Play my game and focus on every point.”
The 25-year-old Serb didn't rip his shirt off this time, as he did to celebrate his epic 5-hour, 53-minute win over Rafael Nadal in last year's final. He just did a little dance, looked up to the sky and then applauded the crowd after the 3-hour, 40-minute match.
