Young, 30, made one start for San Diego this year, picking up the win after six scoreless, one-hit innings April 6 at Arizona. He was originally placed on the 15-day disabled list April 12 (retroactive to April 7) with a strained right shoulder.
"We've shut down any further throwing activity for C.Y. for a couple more weeks," said Padres manager Bud Black. "He's working with our physical therapist with stabilization exercises in the shoulders and some strengthening, letting the entire capsule and joint quiet down. It got pretty heated up there over the course of coming back after his first start.
"He's still a few weeks away with a baseball in his hand. There's some straining of certain muscles in the rotator cuff and in around the capsule, which is common for a lot of pitchers. With C.Y. it was a little more extensive so you need a little more time to let the strains and inflammation calm down."
