What is a Platelet-rich Plasma Injection and Would it Have Helped Bobby Parnell?

In the latest episode of The Fix, Angel Borrelli and I discuss the following:

– How can a pitcher know the difference between “normal soreness” and a pain that requires medical attention?

– What is a “platelet-rich plasma injection” and how could it have helped Bobby Parnell‘s partially torn UCL? (Note, we recorded this episode on Saturday afternoon, prior to the news that Parnell would be getting Tommy John surgery.)

– What is the difference — if any — between a UCL and MCL tear?

Brian Wilson is suffering “ulnar nerve irritation” in his elbow — what is that, and does that mean he needs another Tommy John surgery?

– A new paradigm for preventing pitcher injuries that will allow MLB pitching coaches to sleep soundly at night.

    Good listen.

    Regarding David Hernandez, considering his troubles last year, he had to have concerns about job security.
    I suspect that his elbow issues, or their cause started then, otherwise his extremely erratic performance in June, July and August make no sense.

    Re: TJ injuries, we can’t compare to the 1930s because all sorts of pitchers had short careers for undocumented reasons. We can compare to the last 30 years, though, and there’s clearly been an increase. I’m not sure what’s to blame, but I’d guess:

    1) velocity has long been a ticket to drafting and promotion, but now moreso than ever

    2) saving your bullets by backing off on velocity (e.g. against the bottom of the lineup) is no longer taught (this is mostly stupid, but it may be relevant that there are fewer hitters in the game with zero power than in the ’80s)

    3) pitch counts have replaced observation re: deciding when a guy’s fatigued

    4) the pitching motion that’s most widely taught right now is dangerous

    5) the prep & recovery process that’s used today is ineffective

    6) everyone throws a slider

      Re #3, Patrick Corbin would be a good example. After his 113 pitch effort on August 14 followed by a CG on August 20 he went from phenom to erratic. Rather than shut him down, he racked up 208 innings and is now paying the price.
