From the Mitchell Report:
Lenny Dykstra played as an outfielder in Major League Baseball with two clubs, the New York Mets and Philadelphia Phillies, from 1985 to 1996. As a player with the Phillies, Dykstra played in three All-Star games and finished second in Most Valuable Player balloting in 1993.
Radomski first met Dykstra when he was playing for the Mets and became “very close with Lenny.” According to Radomski, when Dykstra reported to spring training in 1989, “his increased size was noticeable.” When Radomski asked him about his increased size, Dykstra admitted to taking steroids. Radomski also recalled that Dykstra’s weight fluctuated during that spring training. He stated that members of the Mets’ management discussed Dykstra’s weight fluctuations with the team’s athletic trainers and that “the trainers would just laugh.”
… After the Phillies lost the 1993 World Series, Dykstra called Radomski and asked whether Radomski could get Dykstra steroids. Although Radomski does not remember the exact time frame, he recalled providing Dykstra with Deca-Durabolin, Dianabol, and testosterone.
Since approximately 2000, the Commissioner’s Office has been aware that Dykstra used anabolic steroids during his playing career. At that time, senior vice president for security Kevin M. Hallinan, his deputy Martin Maguire, and then-executive vice president for baseball operations Sandy Alderson met with Dykstra and his doctor in an attempt to increase their understanding of steroids. Hallinan said that Dykstra admitted to using steroids, saying that he used them to “keep his weight up” during the season. According to Hallinan, Dykstra said using steroids eliminated the need for him to work out during the season. In order to provide Dykstra with information about these allegations and to give him an opportunity to respond, I asked him to meet with me; he never agreed to an interview.
