Mark McGwire’s less-successful, one-eyed, bodybuilding brother Jay has written a tell-all book claiming he introduced the slugger to steroids. There’s just one problem: so far, no one’s willing to publish it. But Deadspin got its hands on the manuscript, and can share its juiciest tidbits (no pun intended). It all began when Jay shot his eye out with a BB gun.
The younger McGwire then used the insurance settlement to buy high-end steroids and begin a bodybuilding career. When Mark saw the impact, he soon let his brother inject him. Other fun bits:
- In 1998, McGwire switched from Deca-Durabolin to andro in order to slim down.
- A ’roid-raging McGwire once spanked Jay’s 9-year-old stepson, starting an ongoing feud between the brothers.
- Says Jay: “I don’t think being in the Hall of Fame matters a lick to him.”
