NEW YORK (AP) -- Like a runner trapped between bases, the release date for a potentially scandalous Alex Rodriguez book keeps edging back and forth.
Selena Roberts' unauthorized "A-Rod" was originally planned for May, then was moved up to mid-April after Roberts, a Sports Illustrated reporter, broke the news that the Yankees slugger had tested positive for steroids back in 2003.
But with Roberts still working on the book (and Rodriguez recovering from a hip injury), the publication was pushed back to late April and now is planned for May 12, according to publisher HarperCollins.
"That's the on-sale date," publicist Leslie Cohen said Tuesday.
