It was noted in APV's fanshot here that Willis had been placed on the DL because of an anxiety disorder. Detroit had to petition MLB to get the ok on DLing a player for the disorder and it was granted. There seems to be some suggestion that MLB might retract the allowance following criticism about the way WIllis was reportedly diagnosed, through a blood test.
I have never come across an anxiety disorder diagnosis by a psychiatrist (or any other physician) done through blood testing. To my knowledge, no such test is commercially available (i.e. has gotten beyond the research phase), and even if it did it would not be the sole diagnostic criteria. Either Willis and the team are minimizing the diagnostic criteria he presented to the team doctors or this is not an Anxiety Disorder. If it is the latter, I'm wondering what Detroit would gain by having him on the DL instead of sending him down to the minors?
