**The Mitchell Report — the foundational document of modern MLB drug-policy history.** Authored by former U.S. Senate Majority Leader George J. Mitchell (who had previously authored the 2000 Blue Ribbon Report on Baseball Economics, also in this archive). Commissioner Selig named Mitchell as special investigator on March 30, 2006, in the wake of the BALCO investigation, the Jose Canseco book (Juiced, 2005), the March 2005 House Government Reform Committee steroid hearings, and the growing public crisis over the steroid era in baseball. The investigation took 21 months and produced a **409-page report** released December 13, 2007. The Report named **89 current and former MLB players** as alleged users of performance-enhancing substances (most prominently Barry Bonds, Roger Clemens, Andy Pettitte, Miguel Tejada, and Eric Gagne), drawn from documentary evidence (financial records, packaging materials, written communications) primarily provided by **Kirk Radomski** (former Mets clubhouse employee turned cooperating witness) and **Brian McNamee** (Clemens's former trainer). The Report's recommendations included independent program administration (later adopted in the 2008 JDA amendments), HGH testing protocols (then technically infeasible but later adopted in 2013), random off-season testing, and significant transparency reforms. The Report's release triggered the December 18, 2007 House Oversight Committee hearings (also in this archive) at which Mitchell, Selig, and MLBPA Executive Director Donald Fehr testified, and the subsequent February 13, 2008 hearing with Clemens and McNamee testifying about Clemens's alleged use. **The Mitchell Report is the single most-cited document in the entire MLB drug-policy ecosystem.** Substantively, the Report concluded that 'the use of steroids in Major League Baseball was widespread' and that the response to the use was 'slow to develop and initially ineffective.'

Background

The most consequential single document in modern MLB drug-policy history. The Mitchell Report transformed the post-2005-Congressional-hearings landscape from public-pressure-driven incrementalism to comprehensive structural reform. The 2008 JDA amendments (later embedded in the 2007-2011 CBA cycle's continuation) implemented most of Mitchell's recommendations. The Report's named-player list also drove the December 18, 2007 House Oversight Committee hearings (with Mitchell, Selig, Fehr) and the February 13, 2008 hearing at which Roger Clemens and Brian McNamee testified — the latter producing federal perjury indictments against Clemens (eventually acquitted at his second trial in 2012). George Mitchell had previously authored the 2000 Blue Ribbon Report (also in this archive). The Report's procedural choices have been criticized: notably the MLBPA's refusal to cooperate left the witness base limited to non-player sources, and the named-player list was criticized for inconsistent evidentiary standards. Brian McNamee's basement evidence (the syringes and gauze pads with Clemens's purported DNA) became the central evidence in the Clemens perjury trial. The single most important document for any analysis of how the steroid era was handled. Bonds, Clemens, Tejada — the case files. Selig's response. The MLBPA's pushback. The JDA amendments that followed. The Hall of Fame voting debates that the named-player list directly produced. Mitchell, Hocking and Salem (Mitchell's firm at the time, later DLA Piper) was paid $19.6 million by MLB for the investigation.

Overview

Former Senate Majority Leader George Mitchell — the same Mitchell who wrote the 2000 Blue Ribbon Report (also in archive) — was named MLB's special investigator by Commissioner Selig in March 2006. 21 months later, the Report identified 89 current and former MLB players as alleged users of performance-enhancing substances, drawn primarily from documentary evidence provided by Kirk Radomski (former Mets clubhouse employee) and Brian McNamee (Roger Clemens's former trainer).

The substantive conclusion was foundational: "The use of steroids in Major League Baseball was widespread. The response to the use was slow to develop and initially ineffective. For decades, MLB players responded to a culture of acceptance."

Why this is foundational

Every subsequent MLB drug-policy framework descends from the Mitchell Report. The 2008 JDA amendments (later carried into the 2022-26 cycle's JDPTP in this archive) adopted Mitchell's structural recommendations: Independent Program Administrator, random off-season testing, HGH testing (eventually 2013), educational programs, transparency reforms.

The Report also produced the Hall of Fame voting debates over steroid-era players that have shaped post-2010 cooperstown coverage — Bonds, Clemens, Sosa, Tejada, McGwire, et al. all sit on top of this Report's evidentiary record.

Why this matters

This is the single most important document for any analysis of how the steroid era was handled. Bonds, Clemens, Tejada — the case files. Selig's response. The MLBPA's pushback (Donald Fehr raised specific methodology criticisms). The JDA amendments that followed. The Hall of Fame voting debates. Brian McNamee's basement evidence and the Clemens perjury trials.
