Left-hander Atlee Hammaker of the San Francisco Giants reported for spring training minus 19 pounds--down from 220 to 201--but with 88% more body fat than normal.

“I don’t know what the hell I had, or have,” Hammaker told the San Jose Mercury News. “The doctors can’t say what it is. They don’t know what it is. I can’t explain it or pinpoint it, and it hit me out of the blue.”

Manager Roger Craig said: “He’s behind everyone else. We’re just going to have to play this by ear. If he needs more medical attention, we’ll get him some.”

Hammaker says he first noticed a problem last month, just before boarding a ship for a cruise of the Caribbean. By the time the ship reached Barbados, Hammaker said he couldn’t even walk and was forced to take a flight home.
