Per Baker:

Just got the word that Carlos Silva has been placed on the 15-day disabled list with inflammation and stiffness in his right shoulder. Jason Vargas now moves to the rotation in his place and takes Silva's scheduled spot next Tuesday in Arlington, Tex. against the Rangers.

Brandon Morrow comes off the DL today and fills the vacant roster spot.

Silva had stiffness in his shoulder two weeks ago, when he won his only start this season in Anaheim against the Angels. Still, the M's let him go out for two more starts to try to make it work and he couldn't.

.....

Silva will be eligible to come off the DL on May 22.

All righty then.
