World No.8 Mardy Fish and 10th-ranked John Isner will join the world’s top-ranked doubles team of Bob and Mike Bryan on the United States team for next week’s Davis Cup quarter-final tie away in France.

US captain Jim Courier announced the line-up selections on Tuesday, taking the two top-ranked US ATP singles players but leaving out long-time US Davis Cup stalwart Andy Roddick, ranked 34th, a day after he beat the in-form Roger Federer.

“Andy said pretty quickly after we had our victory in Switzerland that Mardy and John should continue on with what they started,” Courier said.

“Andy is not coming nor was that a consideration on his part or on my part but he is available for consideration down the line. If somebody gets injured he would be available. That’s the kind of player he is.”

In the April 6-8 tie on Monte Carlo claycourts, world number six Jo-Wilfried Tsonga is set to lead a French team captained by Guy Forget that also includes Gael Monfils, Michael Llodra and Julien Benneteau.

“I’m not convinced the four players (Forget) has presented are the four players that will be nominated next Thursday,” Courier said. “A great team he has to work with. We know it’s going to be a tricky one all the way around.

“There will be five tough matches for us. We have got to play our absolute best to stand a chance.”

Courier said he did not think the clay surface would hurt big-serving Isner.

“It doesn’t matter what surface he’s playing on. His serve is going to be a nightmare to deal with if he’s having any kind of a normal day,” Courier said.

“He’s confident on clay … not having a mental obstacle, that’s a big part of the puzzle.”

Fish had been unhappy after losing at Indian Wells but was feeling more competitive after triumphs this week in Miami, Courier said.

“Mardy is feeling a lot better having won a couple matches,” Courier said. “He’s in a better frame of mind.”

The US team leads France 8-7 in the all-time Davis Cup rivalry, having won the most recent meeting 4-1 in a 2008 quarter-final at Winston-Salem, North Carolina.

The only US victory in seven ties on French soil came in 1982 when the Americans defeated the hosts in the final at Grenoble.
