Last season, young Reds left-handed pitcher Tony Cingrani was viewed as ready for a full-time spot in the rotation and a central piece in the club’s plans. It enabled Cincinnati to bid farewell to Bronson Arroyo and feel good about its starting five. Then Cingrani struggled early in the year and missed most of the season with a shoulder injury. Before the Winter Meetings last week, he appeared to be on the outside looking in — the sixth man on the depth chart for the rotation.
