The Dodgers spun it as "an abundance of caution." But $147 million is an abundance of money. Right-hander Zack Greinke, who signed as a free agent for six years and $147 million over the winter, left camp for Los Angeles on Monday morning to have his right elbow examined by Dr. Neal ElAttrache. ElAttrache confirmed a diagnosis of inflammation in the back of the elbow but no structural damage to ligaments or tendons – the same diagnosis that followed an MRI last week. Greinke received a PRP (platelet-rich plasma) injection in which blood is drawn from the patient and spun in a centrifuge to extract the concentrated plasma, which is then re-injected into the injured area to promote healing. He also will take anti-inflammatory medication and will not throw for the next two or three days. Dodgers manager Don Mattingly said he believes there is still enough time for Greinke to get ready to start the second game of the season April 2. Greinke began feeling discomfort in the elbow over a week ago. He was scratched from his scheduled start last week, primarily because of the flu, and threw a bullpen session Friday with Mattingly standing in the batter's box. Greinke downplayed the elbow pain at the time, dismissing it as a normal occurrence for him. But the discomfort returned when Greinke played catch Sunday, and the decision was made to send Greinke to Los Angeles for the examination – a decision Mattingly called "ultra-caution at this point in spring training."
