DeSclafani (elbow) threw a side session Tuesday from a bullpen mound and will throw another one later this week before getting slotted for his first spring training start.
The Reds have already stated that DeSclafani won't be ready for Opening Day, though they haven't yet committed to him beginning the year on the DL. In fact, it's been suggested that he could start the second regular season game. However, given the ability to back-date DL stints by having him pitch in minor league spring training games, and given the off-days present early in the season, it also wouldn't be a surprise if he had a brief DL stint.
