I will paste below the passage you presumably referenced. Note also the comment that states that "there are pitchers who get pronator strains who do just fine". Of course its a concern; even Andrews doesn't always get it right. We are both in the medical field, and both of us know that anecdotal evidence doesn't mean much. I looked for real studies about the accuracy of the MRI in diagnosing UCL tears and could find none. I think we can stipulate that they are not 100% accurate, but how inaccurate they are is a matter that hasn't apparently been addressed. To state that there are "a lot" of them, as you did, without the proper data to back it up (because, apparently, such data does not exist-or at least I haven't been able to find it) remains in the realm of anecdotal evidence. The bottom line is this: Price went to perhaps the best doctor in the world, had the best available diagnostic testing, and the treatment that was recommended didn't even include an injection. How he will actually do is anybody's guess. I am sure, as a baseball fan, you wish him nothing but the best.
Here is the passage to which you referred, I believe:
"If you go back and look at all the press releases of Stephen Strasburg in the week before he went down, he was out for a start due to a flexor pronator strain and then shortly thereafter he went down with the Tommy John injury. Those would be words that would at least concern me, but there are pitchers who get flexor pronator strains and do fine. But any kind of medial (inside) elbow pain is worth looking at closely and being very careful with."
