Dan Runzler is expected to miss 4-6 weeks after aggravating the latissimus dorsi muscle in his left shoulder.
Runzler tore the lat muscle in the final game of the regular season last year and felt something in the back of his shoulder during his most recent bullpen session. He visited Dr. James Andrews over the weekend in Florida, but was told that the injury will not require surgery. Instead he’s scheduled to fly to San Francisco in order to undergo a platelet-rich plasma (PRP) treatment. “It’ll speed the process,” said Runzler. “In four to six weeks, I should be game ready. That’s definitely better than we originally thought. We can be aggressive with this.” Runzler expects to begin the season in extended spring training, but hopes to be game-ready by mid-April.
