Courier likes Isner's confidence level

After Bob and Mike Bryan defeated France's Michael Llodra and Julien Benneteau, 6-4, 6-4, 7-6 (4) to give the United States a 2-1 lead in the Davis Cup quarterfinals in Monte Carlo, U.S. captain Jim Courier said he's confident in John Isner, who can clinch the tie beating French No. 1 Jo-Wilfried  Tsonga tomorrow. "Well, the way John played yesterday will give him confidence. It gives us, the team, confidence for sure. He's going to have to come out and play at that level to have a chance to beat Jo," Courier said.
