Texas Rangers righthander Mike Adams gave up three runs in a relief appearance against the Oakland Athletics Thursday night and since then has been shut down with what was called a "mild neck strain". Adams was quoted:

"I'm not right, right now," Adams said. "Physically, I'm not 100 percent. I've been going out there battling, grinding, knowing I'm not 100 percent. Yesterday, luckily we had the lead we had. Had it been a two-run lead, obviously I would have cost us a win. I can't keep doing that. I can't keep putting myself through that and more importantly, I can't do that to my teammates. Had I cost us a win yesterday, that wouldn't have been fair to my teammates."

It's more than a neck strain, and he's definitely "not right". Sunday, the cause of this problem was revealed:

#Rangers Mike Adams has thorasic outlet syndrome. Will try to pitch if he can, but is sidelined for 7-10 days. Will not fly to Oak.

"Thoracic" is the correct spelling, and this is the same thing that sidelined Cardinals starter Chris Carpenter for almost the entire season. It's described in this entry from the U.S. National Library of Medicine as "a rare condition", but if Adams' experience is anything like Carpenter's, he's probably out for the season.
