Earlier today, the Orioles announced that the injury rehabilitation assignment for shortstop Blake Davis with the IronBirds ended, and he returned to the Tides.
The Baysox also announced several rosters moves from the past two days.
Yesterday, Bowie relief pitcher Wilfrido Perez was placed on the disabled list, retroactive to July 5. It's his second trip to the DL so far this season. Perez is 2-0 with a 1.37 ERA in 24 appearances for the Baysox this year.
Today, relief pitcher Josh Perrault was promoted to Norfolk from the Baysox, and infielder Brandon Pinckney heads back to Bowie from the Tides.
Starting pitcher Zach Clark, who was on an injury rehabilitation assignment with the GCL Orioles, was activated from the disabled list. He rejoins the Baysox after making 10 starts for the team last season.
Finally, Orioles shortstop Cesar Izturis joins the Baysox for an injury rehabilitation assignment beginning tonight.
