The Los Angeles Dodgers are perennial World Series contenders, so the only players who will be expendable are veterans without a clear path to playing time and prospects. But you can't trade all your best prospects every year,

The Dodgers traded outfielder Steward Berroa to the Milwaukee Brewers on Wednesday, a rare trade in the middle of a game between two teams playing each other. Berroa, 26, was not on the Dodgers' active roster. He had been acquired from the Toronto Blue Jays in a cash trade on May 12, and played 27 games for Triple-A Oklahoma City since.
