MLB's Role in Reducing the Stigma of Mental Illness?

As ravid baseball fans are no doubt aware of (or maybe not) Khalil Greene, of the St. Louis Cardinals, is on the DL with not a physical injury, but for social anxiety disorder. In a similar situation, Dontrelle Willis also spent time on the DL this year for another mental illness (can't remember what). These are the first two instances in which I've ever heard of players going on the DL or missing games due to mental illness, although I'm sure it has happened before (a little help?). As one who is very familiar with mental illness I can attest to a social stigma, especially attached to men, that exists against mental illness, as well as its debilitating effect on one's ability to even take care of themselves, let alone successfully perform at their occupation at a consistently high level. I find Greene and Willis' stints on the DL with the cause fully disclosed kind of refreshing, especially given the tough-guy, invincible, controlled masculinity that's so espoused in professional sports in the United States. Will acknowledging that one's performance on the field, or whatever the competitive enviornment, has lessened due to mental illness totally reduce the stigma against mental illness? Probably not. Will it help? Probably. But one thing is for sure: it's nice to see athletes admitting their condition and not having the press (as far as I know) trashing them.
