Pittsburgh drug trials

Leonard was one of seven then-current or former major league baseball players who testified at the 1985 cocaine trafficking trial of Curtis Strong, which became known as the
Pittsburgh drug trials Pittsburgh ( ) is a city in Allegheny County, Pennsylvania, United States, and its county seat. It is the second-most populous city in Pennsylvania (after Philadelphia) and the 67th-most populous city in the U.S., with a population of 302,9 ...

suspended 11 players on February 28, 1986, including Leonard. Ueberroth interviewed the involved players during the off-season at the end of that year, and imposed sanctions against players for their apparent involvement in the cocaine network. Leonard was among a group of players that Ueberroth cited as having had a "prolonged pattern of drug use" and had involvement in cocaine distribution; these players were issued one-year suspensions from Major League Baseball, however, the suspensions were to be waived in exchange for donations to drug-treatment programs, and community service performed with drug-related organizations. The donations for many, including Leonard, were to amount to 10% of their base salaries (in Leonard's case, this amounted to $80,000) and players had to submit to drug testing for the rest of their careers. The Pittsburgh drug trials are considered one of Major League Baseball's biggest scandals of all time, albeit one that was "behind the scenes" and did not affect play on the field.
