Think things couldn’t get any worse for Ted Williams, the Splendid Splinter, the last man to hit over .400, considering he’s dead and frozen.

Think again.

According to a new tell-all book, “Frozen,” penned by Larry Johnson, a former executive at the Alcor Life Extension Foundation in Scottsdale, Arizona, shortly after Williams’ body arrived at the cryonics lab, he was beheaded using crude equipment, and his frozen head was abused and degraded by unqualified technicians.

But it gets worse…way worse.

Allegedly workers used Williams’ frozen head for batting practice, after it had become stuck to a tuna can…by using a monkey wrench.

Here are some of the more appalling excerpts from Johnson’s book…

Johnson writes that holes were drilled in Williams’ severed head for the insertion of microphones, then frozen in liquid nitrogen while Alcor employees recorded the sounds of Williams’ brain cracking 16 times as temperatures dropped to -321 degrees Fahrenheit.

Johnson writes that the head was balanced on an empty can of Bumble Bee tuna to keep it from sticking to the bottom of its case.

Johnson describes watching as another Alcor employee removed Williams’ head from the freezer with a stick, and tried to dislodge the tuna can by swinging at it with a monkey wrench.

The technician, no .406 hitter like the baseball legend, missed the can with several swings of the wrench and smacked Williams’ head directly, spraying “tiny pieces of frozen head” around the room.

Johnson first spoke out against his former employer in 2003, and went into hiding while writing “Frozen,” fearing for his life.

The book comes out Tuesday, with Johnson scheduled to make an appearance on ABC’s “Nightline.” [NY Daily News]
