Miami, FL (SportsNetwork.com) - Former Biogenesis of America owner Tony Bosch was sentenced to four years in prison by a federal judge on Tuesday.

Bosch pleaded guilty in October to a charge of conspiracy to distribute illegal drugs, including steroids and testosterone to Major League Baseball players.

U.S. District Judge Darrin Gayles sentenced Bosch and ordered him to surrender immediately.

Bosch ran a now-defunct anti-aging clinic in Florida that was at the center of an extensive investigation by MLB in the summer of 2013. The probe led to the suspensions of 15 players for using performance-enhancing substances, most notably Alex Rodriguez, who sat out the entire 2014 season as a penalty for his role in the scandal.

Rodriguez is set to return to the New York Yankees this season.

Bosch cooperated with authorities, including the Drug Enforcement Administration, and also helped Major League Baseball in its investigation.

His testimony led to the Commissioner's Office levying an unprecedented 211- game suspension of Rodriguez that ran through the entire 2014 season. 2011 National League MVP Ryan Braun and 2014 American League home run champion Nelson Cruz were among the players who received lighter bans after being connected to Biogenesis.
