Luis Guerrero Injury: Initiates rehab assignment

Guerrero (elbow) began a rehab assignment with High-A Greenville on Tuesday and worked around three walks and one hit in a scoreless inning in his first appearance.

The one-inning outing marked Guerrero's first appearance at any level since June 27, as he's been on the shelf for two months while recovering from a right elbow strain. Guerrero is expected to eventually shift his rehab assignment to Triple-A Worcester, and once he gets a few more minor-league appearances under his belt, he could re-emerge as an option for Boston's bullpen.
