Manager Mark Kotsay said Thursday that Guerra (forearm) will receive a second opinion, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

Guerra was evaluated for forearm tightness Tuesday, but he'll get an additional diagnosis before the team determines the next steps in his recovery process. The right-hander was in line to serve as one of the team's top setup men in front of closer Lou Trivino to begin the regular season, but his early-season availability will likely depend on the results of his second examination.
