This afternoon the Pirates announced that Wandy Rodriguez has received a "PRP injection" (Platelet Rich Plasma). The pitcher will "only" rest, receive treatments and rehabilitate for "up to three weeks."
* Some information about PRP injections from Science Daily
* From Los Angeles Times: "Several Dodgers have used platelet-rich plasma therapy" (March 13, 2013)
* Ben Lindbergh recently wrote a piece about PRP injections for Baseball Prospectus. Take a look - "Overthinking it: Dylan Bundy, Elbow Injuries, and the Evidence that PRP Works."
* Also, Pat Lackey of Whygavs.com has an interesting post on the procedure and Wandy's future.
