Time to turn to the professionals (well, they should be) about what’s changed about Shaun Marcum since his return from the DL. here’s what
“It’s typically the other way around – arm slot drops as injury sets in. Additionally, it’s almost always due to a shoulder problem, not elbow. In one sense, you could use the glove arm to tighten against the chest (like I tell pitchers to do) and gain flexion about the elbow, thus protecting against slamming the olecranon process into the hyaline cartilage. It might be a function of that, but beyond that, I can’t say.”
I also noticed that Chris Neault of the Disabled List Informer nicely predicted Marcum’s second stint on the DL at Fantasy Phenoms (the whole article is worth reading, as well as its sister over at THT) and chastised the Jays for sending him out there in June even though his elbow was barking:
Marcum began having right elbow soreness in the early part of June this season, but continued to pitch despite the symptoms being present. This is one of things that simply should not be allowed to happen, especially with a pitcher.
Back in 2007, Chris O’Leary put Marcum on a list of pitchers that make him nervous due to how high their pitching side elbows get (apparently Marcum’s arm action shows both Hyperabduction and an Inverted W). I think you have to scroll about halfway down this page to see the articl (and once you’re there you may as well read the next one about A.J. Burnett as well).
If this isn’t all vaguely terrifying enough, I’ll see if I can get Gustavo Chacin to provide a quote on why Marcum might not be throwing his cut fastball any more. Marcum makes his second start in AAA tonight.
