Michael Gonzalez began his injury rehab assignment today with the Gulf Coast League Orioles, throwing a scoreless first inning before Aaron Swenson replaced him. Gonzalez allowed a two-out single and struck out two. He retired the other batter on a pop up to first baseman Tyler Townsend. Felix Pie is serving as the designated hitter again and batting third. He's 0-for-2 with a strikeout and fly ball. Update: The Orioles optioned Chris Tillman to Triple-A Norfolk to make room for newly acquired utility man Jake Fox. The Orioles also designated reliever Cla Meredith for assignment.
