Tyson Ross felt good after Saturday's rehab start for Triple-A Round Rock, but the Texas Rangers aren't sure when he'll pitch again.

It's possible that Ross could make his first start for the Rangers next weekend against the Washington Nationals.

"It comes down to how he feels the next few days, going through the progression and his overall health," Jeff Banister said.

Ross has been on the disabled list since the beginning of the season while recovering from offseason surgery on his right shoulder for thoracic outlet syndrome. He has made three starts for Round Rock.
