Mike Pelfrey has Tendinitis
It’s been reported that Mike Pelfrey has tendinitis in his forearm.
Uh-oh. That’s typically a precursor to an elbow strain.
TheRopolitans has good coverage of this issue and a description of tendinitis. (The site also has a new slick look, so check it out … seems everyone is changing their look these days.)
In my experience, throwing sliders can cause and agitate forearm and elbow issues, because a righthander has to turn his hand clockwise (also called “supination”) at release, which can put a strain on the forearm and elbow ligaments. In contrast, a properly thrown fastball usually includes a slight pronation of the hand (counter-clockwise turn) during the acceleration of the arm and through the release. Luckily Big Pelf is not using the slider much anymore, but it’s still a concern. Last year Billy Wagner reported a similar injury prior to needing Tommy John surgery.
