New A-Rod speculation surfaces in book

Slugger reportedly used steroids in school, with Yanks

The upcoming book about Alex Rodriguez suggests he used performance-enhancing drugs after 2003 while with the Yankees and cites a high school teammate saying Rodriguez used steroids in his youth, according to a report in the New York Daily News.

"A-Rod: The Many Lives of Alex Rodriguez," by Sports Illustrated reporter Selena Roberts, is due out May 12. The Daily News said it includes sources from inside the Yankees clubhouse who suspected Rodriguez of using banned substances while with the club, which Rodriguez has denied publicly.

Following allegations in an SI.com article that preceded the magazine's release of a cover story in February, Rodriguez admitted to having taken performance-enhancing drugs in 2001-03 while with the Rangers. SI reported that Rodriguez failed a drug test for Primobolan and testosterone in 2003.

Roberts' book, the Daily News report said, claims that teammates remarked about physical traits in Rodriguez that could have been attributed to steroid use upon his arrival in New York, and that one unnamed Major Leaguer said Rodriguez and former pitcher Kevin Brown were seen together with human growth hormone in 2004. Brown denied that claim through his attorney, the report said.

Rodriguez also said during his press conference in February that he did not use performance-enhancing substances before 2001, including in high school. But, according to the Daily News, Roberts' book cites a former teammate at Westminster Christian High School in Miami saying Rodriguez was on steroids and his coach knew it. However, coach Rich Hofman said, "Whatever he was doing, he was doing it somewhere else."

Rodriguez, who is recovering from March 9 hip surgery, declined to comment about the article following his first rehab game Thursday afternoon in Tampa.

"I'm not going there," Rodriguez told reporters. "I'm just so excited to be back on the field and playing baseball. My team's won two games [in Detroit]. Hopefully I can come back and help them win some more."

According to the Daily News, the book also includes allegations of Rodriguez tipping pitches to opponents during lopsided games, as well as details of his personal life.
