Feldman suffers setback after throwing

HOUSTON -- In his first baseball activity since exiting his Sept. 1 start with discomfort in his right shoulder, Scott Feldman experienced more discomfort while playing catch on Saturday and will be reevaluated.

"It didn't go particularly well," Astros manager A.J. Hinch said after Saturday's 3-2 loss to the Twins. "We'll have to regroup and find out what is next for him."

MRI tests on Wednesday revealed no tear in Feldman's shoulder. He received an injection and didn't pick up a baseball until playing catch on Saturday. Feldman said after the game he felt discomfort throughout playing catch and was unsure when exactly he'd be reevaluated.

Astros catcher Jason Castro hopes to begin running and easing in to more strenuous catching activities on Monday as he recovers from a right quad strain that put him on the disabled list on Aug. 29.

Castro said he's progressed well in the days since the injury, working on range of motion exercises to strengthen the quad before upping the activity.

"That's part of what we're looking at as far as the rehab process and kind of the checklist of things I need to do in order to come back," Castro said. "That's kind of where we're headed next, seeing how I respond to not only just the running part of it, but getting back to some catching activities and going from there."

Hinch, a former catcher himself, said the team plans to test Castro to a point of not allowing any setbacks, but didn't speculate when the Astros may welcome Castro back to the lineup. Hank Conger and newly-recalled Max Stassi have assumed the duties behind the plate since Castro's injury.

"He'll get into different positions, do a little more mobility stuff, a little more agility stuff and gently introduce more athletic activities to him where it's not just the rehab treatment, not just the training room treatment, it will be more activity," Hinch said. "We'll push him to the point of testing him, but we're being very cautious not to push him too hard."
