SAN DIEGO -- Geoff Blum's sore elbow did not show any signs of improvement on Saturday after the infielder felt a "pop" in his right elbow on Thursday caused by loose bodies in the area.
Blum arrived at the ballpark on Saturday in pain and without the ability to even extend his arm, let alone participate in any baseball-related activities.
"Even brushing my teeth hurts right now," Blum said. "It hasn't gotten any better at all."
Astros manager Brad Mills said prior to Saturday's game that the team had yet to receive the results of an MRI taken on Blum's elbow that may help determine a course of action. Blum is listed as day-to-day for now.
"As of right now, we're waiting for the doctor to bring the MRI in, and he hasn't shown up yet," Mills said. "[Blum] showed up this afternoon to get treatment, and it was still swollen, and he still can't straighten it out. So we're kind of in a state of flux here a little bit, to see what the MRI has to say and go from there."
With shortstop Tommy Manzella also on the shelf, the recently acquired Angel Sanchez got the start again on Saturday after collecting a single and making two defensive plays in his debut with the team on Friday.
