Barry Bonds' cleat size has grown 2 1/2 sizes since he joined the team prior to the 1993 season, according to new material in the paperback edition of "Game of Shadows," to be released this week, Sports Illustrated said.

Authors Lance Williams and Mark Fainaru-Wada write about the massive growth in Bonds' jersey size (42 to 52), cleat size (10 1/2 to 13) and cap size (7 1/8 to 7 1/4) — even though he is shaving his head bald now.

"The changes in his foot and head size," says the book, "were of special interest: medical experts said overuse of human growth hormone could cause an adult's extremities to begin growing, aping the symptoms of the glandular disorder acromegaly."

Williams also told SI he thinks Bonds might be indicted for perjury in the next six months.

"My gut feeling is we're going to know before the end of the season," Williams said. "I think they'll come to some resolution [on whether to indict] and we'll hear about it."

Williams told SI that he thinks the prosecution "intended to indict last season" but that Kevin V. Ryan, the United States attorney for the Northern District of California, wanted former Bonds trainer Greg Anderson's testimony.

But he "has shown no intention to ever participate," Williams says of Anderson, who is serving a third prison sentence for his refusal to testify about Bonds to a grand jury.

The authors also said that Bonds has yet to challenge any of the facts in the book, which alleges Bonds' extensive use of performance enhancing drugs, like HGH and steroids.
