(AP) -- Mark McGwire says he doesn't plan on ever seeing again his estranged brother, who wrote a book about their use of performance-enhancing drugs.
 
McGwire says Thursday that he knew his brother Jay McGwire was writing a book but he was still saddened to know a relative could "do something like that."
 
Jay McGwire chronicles Mark's use of steroids and human growth hormone in "Mark and Me: Mark McGwire and the Truth Behind Baseball's Worst-Kept Secret." The book, to be released Monday, says Big Mac knew he became a better hitter because steroids enhanced his size and strength.
 
The brothers haven't spoken since 2002.
