An MRI on righthander Felipe Paulino showed no structural damage, but the Astros will not let their top pitching prospect throw for at least a month after Paulino was diagnosed with a pinched nerve in his upper right arm.
"When you think about everything that is happening, that’s not bad news," manager Cecil Cooper said. "Little disappointed to hear it, but at least there’s no structural damage."
The pinched nerve is the second health problem for Paulino this spring. Earlier in camp, Paulino had an infection cut out of his foot. The 23-year-old was competing for a spot in the Astros rotation, but now he may begin the year at Triple-A Round Rock instead.
