Padres manager Bud Black said Tyson Ross will rejoin the rotation once his left shoulder is healed.

Ross is obviously healthy enough to pitch, but his left shoulder subluxation leaves him unable to swing a bat, meaning he can only pitch in relief for now. There's no timetable for when he'll be ready to swing again. "We still see him as a starting pitcher," said Black. "But that will be left shoulder related and whether he's physically able to do that. Right now, his strength is improving. In due time, he has to get in a cage."

Tyson Ross (shoulder) will begin a rehab assignment with Triple-A Tucson this week.

Out with a left shoulder subluxation, it's not clear how many rehab starts Ross will need before being activated. He's not a given to be re-inserted into the rotation when ready.

Tyson Ross (shoulder) remains at risk of missing Tuesday's scheduled start against the Brewers due to a subluxation in his left shoulder.

Ross still maintains that he'll be able to give it a go, but manager Bud Black is proceeding with caution. While he has improved in recent days, they don't want to risk him doing further damage if he isn't feeling percent.
