The Mitchell Report exposes a "serious drug culture within baseball, from top to bottom," fingers MVP's and All-Stars, and calls for beefed-up testing by an outside agency to clean up the game, The Associated Press learned Wednesday. The report by former Senate Majority Leader George Mitchell will include names of 60 to 80 players linked to performance-enhancing substances and plenty more information that exposes "deep problems" afflicting the sport, one of two sources with knowledge of the findings told the AP. Both sources said the report would not address amphetamines. The two sources were familiar with discussions that led to the final draft but did not want to be identified because it was confidential until its scheduled release on Thursday. They said the full report, which they had not read, totaled 304 pages plus exhibits. One person familiar with the final version would only speak anonymously but described it as "a very thorough treatment of the subject" and said some aspects were surprising. He said the report assigns blame to both the commissioner's office and the players' union. MLB is "not going to love it; the union's not going to love it," he said.
