MIAMI - More than 80 years ago, Germany sold tens of thousands of bonds to American investors in an effort to recover financially from World War I. Later, Adolf Hitler used some of the money raised by those bonds to build the powerful Nazi war machine that would ravage Europe during World War II.

Now, a half-dozen U.S. bondholders are turning to federal courts in an effort to force Germany to make good on its promise to repay the debts, which today could be worth hundreds of millions, if not billions, of dollars.

Action has been heating up in lawsuits filed in Miami, New York and Chicago, including a victory for investors last month when an appeals court rejected Germany's attempt to dismiss their case.

NEW YORK - What could have been a great day for American tennis instead turned into a dominating afternoon for Novak Djokovic.

19-seeded American Mardy Fish, 6-3, 6-4, 6-1 on Monday, sapping the energy from both his opponent and nearly packed Arthur Ashe Stadium and leaving only one American man in the draw at the U.S. Open.

Against Fish, who has played two five-setters in addition to doubles over the first week, the Serb was the better, fresher player.
