RHINEBECK, N.Y. - Chelsea Clinton wed her longtime boyfriend under extraordinary security at an elegant Hudson River estate late Saturday.

Bill Clinton and Hillary Rodham Clinton announced in a statement that their daughter wed investment banker Marc Mezvinsky after weeks of secrecy and buildup that had celebrity watchers flocking to the small village of Rhinebeck for the evening nuptials.

"Today, we watched with great pride and overwhelming emotion as Chelsea and Marc wed in a beautiful ceremony at Astor Courts, surrounded by family and their close friends," the Clintons said.

Former All-Stars Jake Westbrook, Ted Lilly, Ryan Ludwick and Kerry Wood were traded Saturday as pennant contenders played a game of beat-the-clock.

Lance Berkman went to the World Series champion New York Yankees after rejecting the Chicago White Sox.

The NL Central-leading St. Louis Cardinals were the prime players in a three-team trade, getting Westbrook from Cleveland and sending Ludwick to NL Central-leading San Diego.
