Dunning (elbow) is throwing pain-free, James Fegan of The Athletic reports.
Dunning's season ended in June thanks to an elbow sprain, but he's back to throwing side sessions with no pain after a lengthy period of rest and rehab. The young right-hander, who posted a 2.71 ERA, 1.19 WHIP and 10.4 K/9 across 86.1 innings (15 starts) in the minors prior to getting hurt, should be ready to go by the start of spring training barring any setbacks.
