Felipe Paulino (elbow) was scratched from a scheduled rehab start on Sunday due to back stiffness. The Royals are viewing it as a minor setback, as Paulino could be ready to return to the hill on Wednesday. "We want to see him have a good side session and a functional return on fielding his position," trainer Nick Kenney said, "for us to feel comfortable with him pitching on Wednesday." Paulino tossed five scoreless inning in his first rehab outing last week.
