LAKELAND, Fla. — Houston Astros right-hander Felipe Paulino will miss at least a month because of a pinched nerve in his upper right arm.

Paulino traveled to Houston on Monday to be examined by team physician Dr. David Lintner. X-rays showed no structural damage to Paulino's right shoulder. Paulino, who will receive anti-inflammatory medication and daily treatment, won't throw for at least one month.

The 24-year-old, competing for a spot in Houston's rotation, allowed four hits and five runs in two outings this spring.
