Offseason

Steve Bechler

On February 16, 2003, towards the beginning of Orioles' spring training camp in Fort Lauderdale, Florida, Steve Bechler collapsed while participating in conditioning drills. He was rushed to a nearby hospital, and died the next day. His body temperature had reached 108 F. An autopsy performed by Dr. Joshua Perper, a toxicologist, concluded that his death was caused by "'abnormal liver function and mild hypertension', his weight problem (he weighed 230 pounds and was exercising hard, the fact that he was not used to south Florida's warm weather and the toxicity of ephedra. He was using the supplement ephedra, against the advice of his trainer, and probably had not eaten in two days in an effort to lose weight.
