Federer heads to the U.S. Open feeling healthy and fine-tuned. He skipped the Rogers Cup in Toronto last week, giving himself some time to recover from the Olympics in London.
He also has regained the upper hand against one of the players who stands in his way.
Djokovic had put together a run of three straight wins over Federer in tournament semifinals, starting with the U.S. Open last year. Federer turned it around by beating the Serb in the semis at Wimbledon last month.
"It was a final today, so I really wanted to win," Djokovic said. "There is no question about it. Maybe playing couple weeks in a row, four weeks in a row, got to me maybe mentally. Physically it didn't. I felt OK on the court."
China's Li Na won the women's title, beating Germany's Angelique Kerber, 1-6, 6-3, 6-1. It was Li's first title since her breakthrough season in 2011, when she won at Sydney and the French Open. Three times this season, she made it to the finals of a tournament. All three times, she lost in three sets.
