FORT LAUDERDALE, Fla. — Former major league baseball player Jim Leyritz had a blood-alcohol level more than twice Florida’s legal limit when he ran a red light after a night of drinking and crashed into a woman’s vehicle, killing her, a prosecutor said Monday as testimony began in Leyritz’s DUI manslaughter trial.

Stefanie Newman, an assistant state attorney, told a jury that a toxicology expert estimated Leyritz’s blood-alcohol level at the time of the December 2007 crash was 0.18, based on a blood test taken about three hours later that found a 0.14 level. Florida’s legal limit is 0.08.
