Padres have no timetable for starter's return

Ross progressing, but not ready to throw

SAN DIEGO -- Right-hander Tyson Ross has moved to the next step in his rehab process as he continues to recover from a strained right shoulder that he suffered during the season's first week. But Ross has not begun throwing, and manager Andy Green says there's still no timetable for a return.

According to Green, Ross recently completed his first set of stabilization exercises. He's moved onto another phase of his recovery, in which he'll strengthen the entire arm.

"He's still doing his stabilization exercises, feeling good," Green said. "That process is ongoing until they determine that it's time to pick up a ball and throw."

Ross pitched for the Padres on Opening Day and was placed on the disabled list shortly thereafter. His absence has been tough on the Padres. Ross owns a 3.16 ERA since joining the Padres in 2013.

"I'm not holding my breath, I'm just excited whenever I hear he's got a ball in his hand," Green said. "... He's feeling good, so that's exciting."

In other injury news, Cory Spangenberg (left-quad strain) and Yangervis Solarte (right-hamstring strain) got a breather Wednesday after running and taking batting practice on consecutive days. There's still no timeline for when they will begin their rehab stints.

"They're making progress," Green said. "It's been slow progress. Like I said before with Spangenberg, his game is built on speed. You've got to be really aware of that when you make a determination to send him out."

Meanwhile, lefty reliever Matt Thornton (left Achilles tendinitis), is still throwing bullpen sessions, and Green said he's at practically at full strength, arm-wise. The problem is that Thornton can't yet run at full speed, without risking further injury, which makes defending his position almost impossible.
