U.S. Davis Cup captain Patrick McEnroe has high hopes the leg injury that forced Andy Roddick to retire in a match Wednesday against Andy Murray at the Miami Masters won't prevent the hard-serving right-hander from playing against Spain in the Cup quarterfinals April 6 to 8.

Roddick was forced to retire from his quarterfinal with a hamstring injury, handing a 5-3 victory to the Briton.

"It's a positive report," said American captain Patrick McEnroe. "The MRI came up negative.

"Andy tweaked a hamstring in the upper left part of his leg in about the fourth game of the match," McEnroe added. "The good news at least is that it is not torn, but it is a hamstring so that is kind of tricky."

Roddick and James Blake have been selected for the United States Davis squad which will face Spain in North Carolina.

"The word is from Andy that he is going to do everything he can to try to play in Davis Cup," said the skipper. "That's great news to my ears, the captain's ears.

"If he can't play, we'll have a better idea in about three days how he has come up. The problem is that it is not the sort of injury that you can play through.

"It will either heal quickly and he'll be able to practice for a few days and be able to go or he won't and we obviously will have to go to plan B.

Spain's Rafael Nadal will rest a right foot problem instead of playing. The tie will be a replay of the 2004 final, which Spain won in Seville.
