The American guys battle for Davis Cup this weekend...

The defending champion US team has its work cut out for it this weekend as it battles Spain and Rafael Nadal in the semifinals of the Davis Cup competition. Spain is a heavy favorite since the matches are being played on slow red clay - not the US team's strong point.

While I expect the Americans to lose (but hope they win!), it's still fun to see them. Mardy Fish, (above) having the best year of his career, looks like he's about to plant a big wet one on his double's partner Mike Bryan. Mardy was a last-minute replacement for Mike's twin brother, Bob Bryan, who is suffering from a shoulder injury.

Meanwhile, the team's leader and best player, Andy Roddick, will play singles against Nadal. Andy can beat Rafa but not on red clay - no way. But maybe he'll have something to prove after his tough US Open loss and the terrible year he's had since getting injured in April.
