Based on a quick review, there are no current Chicago Cubs players linked to performance enhancing substances in the Mitchell Report. There are, however, a number of former Cubs discussed, along with rumored acquisition target Brian Roberts. Sammy Sosa's name is absent, other than a brief mention that he declined to answer Mitchell's questions.

Larry Bigbie told Mitchell that "Roberts admitted to him that he had injected himself once or twice with steroids in 2003." Roberts declined to meet with Mitchell.

Much of the rest of the information concerning former Cubs comes from former New York Mets trainer Kirk Radomski:

• Radomski sold performance-enhancing substances to former Cubs catcher Todd Hundley, according to Radomski. Hundley declined to meet with Mitchell. One of Hundley's teammates with the Dodgers, Chris Donnels, stated he had "extensive discussions with Hundley about his performance enhancing substance use and about Radomski while they were teammates."
• According to Radomski, Matt Franco purchased steriods from him on one occasion in 2000. Franco denied the allegation and denied ever knowing or hearing of Radomski.
• According to Radomski, Rondell White purchased performance enhancing substances from him beginning in 2000.
• Glenallen Hill admitted that he purchased performance enhancing substances from Radomski in 2000 or 2001, but denied ever using them.
• According to Radomski, former Cubs catcher Todd Pratt purchased steriods from him while Pratt was a member of the New York Mets.
• According to Radomski, former Cubs relief pitcher Kent Mercker purchased one kit of human growth hormone from him in October 2002.
• According to Radomski, he sold human growth hormone to Jerry Hairston, Jr. on two or three ocassions during 2003 and 2004.

Additionally, former Cubs reliever Matt Karcher provided the following information to Mitchell:

Karchner said that during spring training in 1999, he observed two of his Chicago Cubs teammates inject themselves with steroids in an apartment that Karchner was sharing with them. Karchner declined to identify the players. He said that one of the players brought the steroids to the apartment but was afraid of needles and therefore asked the second player to administer the shot. The second player injected the first player with steroids in the buttocks and then injected himself. Later that season, Karchner was offered steroids by certain of his Cubs teammates. Karchner would not disclose the names of players who offered him steroids, but he said that the conversations he had with them involved the general cost of steroids and discussions of “stacking” to build lean muscle necessary for pitchers. Karchner did not report either of these incidents to anyone at the time.
