A decision has  been on what to do with struggling right-hander Carlos Silva.

He was placed on the 15-day disabled list today.

The move was made to make room on the 25-man roster for right-handed closer Brandon Morrow, who was activated from the 15-day disabled list.

“Back in Anaheim, he had some shoulder inflammation back there and since that time he has battled it and I think we need to get him right and get him healthy,” manager Don Wakamatsu said. “Now is the time to do that.”

Left-hander Jason Vargas replaces Silva in the rotation and will start Tuesday night’s game against the Rangers in Arlington.

“We want want to find out about some of the young guys, too,” Wakamatsu said. “He’s a guy that we liked in Spring Training and he pitched well at Triple-A to start the seasona and now we have a need to see him out there. He has shown us a lot in the games he has pitched.”

Silva, in the meantime, will receive treatment on his shoulder, step back and let his mind rest for awhile. Besides the ailing shoulder, he has been fighting himself.

The plan is for Silva to eventully throw some bullpens and at least one or two simulated games before returning to the rotation.
