A search of the Mitchell report on performance-enhancing drugs in baseball (read it here) found no mentions of current members of the Red Sox.
Former members of the Red Sox linked to performance-enhancing drugs in the report include Roger Clemens, Mo Vaughn, Eric Gagne, Brendan Donnelly, Steve Woodard, Jose Canseco, Manny Alexander, Paxton Crawford, Jeremy Giambi, Josias Manzanillo, Chris Donnels, Mike Lansing, Kent Mercker, and Mike Stanton.
More than a dozen Yankees, past and present, were among the 80-plus players identified.
Here's an interesting excerpt from the report regarding the Red Sox’ pursuit of Gagne. Boston traded for the relief pitcher in the middle of last season:
When the Boston Red Sox were considering acquiring Gagné, a Red Sox official made specific inquiries about Gagné’s possible use of steroids. In a November 1, 2006 email to a Red Sox scout, general manager Theo Epstein asked, “Have you done any digging on Gagne? I know the Dodgers think he was a steroid guy. Maybe so. What do you hear on his medical?” The scout, Mark Delpiano, responded,
"Some digging on Gagne and steroids IS the issue. Has had a checkered medical past throughout career including minor leagues. Lacks the poise and commitment to stay healthy, maintain body and re invent self. What made him a tenacious closer was the max effort plus stuff . . . Mentality without the plus weapons and without steroid help probably creates a large risk in bounce back durability and ability to throw average while allowing the changeup to play as it once did . . . Personally, durability (or lack of) will follow Gagne . . ."
Another interesting revelation in the portion of the report about Donnelly:
In considering whether to trade for Donnelly in 2007, Red Sox baseball operations personnel internally discussed concerns that Donnelly was using performance enhancing substances. In an email to vice president of player personnel Ben Charington dated December 13, 2006, Zack Scott of the Red Sox baseball operations staff wrote of Donnelly: “He was a juice guy but his velocity hasn’t changed a lot over the years . . . If he was a juice guy, he could be a breakdown candidate.” Kyle Evans of the baseball operations staff agreed with these concerns, responding in an email that “I haven’t heard many good things about him, w[ith] significant steroid rumors.”
At about 6 p.m., the Red Sox released the following statement in reaction to the Mitchell Report: "The Boston Red Sox have supported and fully cooperated with this investigation initiated by Commissioner Selig and conducted by Senator Mitchell. The Senator and his staff should be thanked and commended for their dedicated and independent efforts in producing this important report. It is imperative that we continue to educate our players on the dangers and unfairness of performance enhancing drugs and to do everything we can to eliminate them entirely from the game of baseball. We are confident that that adoption and implementation of Major League Baseball’s and the Major League Baseball Players Association’s Joint Drug Prevention and Treatment Program, the toughest in all of professional sports, will also result in helping to achieve this goal. Until we have had the opportunity to read and review more thoroughly the Mitchell Report released today, we will have no further comment at this time."
George Mitchell, who oversaw the report, is a director of the Red Sox, and some questioned whether that created a conflict.
"Judge me by my work," Mitchell said. "You will not find any evidence of bias, special treatment, for the Red Sox or anyone else. That had no effect on this investigation or this report, none whatsoever."
