Davis is not the picture of health. He has, in fact, contracted Valley or Desert Fever, a malady that can interfere with a season and even end a career.
His illness has set off no alarms in the Mets' camp. Truth be told, the diagnosis is not a topic of public discussion or much private dialouge. But there is an awareness, and, behind that, a concern.
There's been no official diagnosis, because blood tests that Davis took a week and a half ago have yet to return. Regardless, no one is quite sure on what 'Valley' or 'Desert' Fever is.
