NEW YORK (AP) - Mark McGwire's youngest brother says in a book proposal that he injected the former baseball star with steroids, according to deadspin.com.
Jay McGwire is circulating a manuscript titled "The McGwire Family Secret: The Truth About Steroids, A Slugger and Ultimate Redemption," the web site reported Wednesday.
Jay McGwire is a body builder. He says his brother started using steroids in 1994.
Jay McGwire has a strained relationship with his brother. He could not be reached for comment Thursday.
Mark McGwire repeatedly has denied using illegal performance-enhancing drugs. When he testified under oath before Congress in 2005, however, he wouldn't discuss whether he did.
