Lenny Dykstra, the 1980s World Series hero who pleaded guilty earlier this year to bankruptcy fraud, was sentenced yesterday to six months in federal prison and ordered to perform 500 hours of community service, Reuters reported yesterday. The former ballplayer - who is already serving time in state prison for grand theft auto, lewd conduct and assault with a deadly weapon - was also ordered to pay $200,000 in restitution. In the federal case, Dykstra pleaded guilty in July to bankruptcy fraud and other charges. According to the written plea agreement, he admitted defrauding his creditors by declaring bankruptcy in 2009, then stealing or destroying furnishings, baseball memorabilia and other property from his $18.5 million mansion.
