After losing to Marin Cilic in the third round of Miami, John Isner says he’s looking forward to the U.S. Davis Cup team’s tie next week at home in Boise, Idaho, against the Novak Djokovic-led Serbia team.
“I'm not physically tired; I'm not mentally tired,” Isner told reporters. “I'm healthy. [I will] go back, train, and try to get my ass in gear for Davis Cup. That's a big task for our team, a big task for me.”
