baseball's All-Star break with the worst record

National fire Manager Manny Acta

Washington -- The Washington Nationals, who entered baseball's All-Star break with the worst record in the major leagues, Monday fired Manager Manny Acta.

Acta was in his third season as the Washington manager. He amassed a record 158-252. A loss Sunday in Houston dropped the Nationals to 26-61 this year, which would be a 48-114 record over a full season

The loss total would be the highest since the Detroit Tigers lost 119 games in 2003. The record for losses in a season is 120 by the 1962 New York Mets.
